Volume 13 Chapter 2 - Ecstasy Hybrid

Part 1

「You girls heard her! We will fight the mechanized angels! Hold out until Osiris and Odin bring Kizuna back!!」

Aine too clenched her fist hearing Reiri’s order.

──’Kizuna. I’ll absolutely hold on no matter what until you return!’

And then she glared at the approaching large army of mechanized angels.

「Sylvia, Yurishia, Gravel, lay out the barrage! Himekawa and Grace, take care of the ones that get through! Hyakurath, Aine and I will be the last line of defense! You all got that!?」

「Roger that!」

Aine replied so and she was going to dash. In that timing,

「Uuh……」

She was stopped by a groaning voice.

──’Don’t tell me,’

When she turned around, Kizuna was opening his eyes slightly on Osiris’s lap.

「Kizuna!!」

Everyone turned around hearing Aine’s voice.

And then, seeing Kizuna’s figure lifting up his upper body, their eyes opened wide in shock and happiness.

「Kizuna!!」

「Kizuna-kun!」

「Kizuna!?」

「Captain!!」

Many yells were raised while they looked like they were going to rush towards Kizuna’s position. However──

「Wait!」

A small body stood in their way before they could.

「Kizuna’s resurrection isn’t over yet! Hold back the enemy!!」

「You……」

For a moment Reiri forgot herself at the sudden appearance of her mother──Hida Nayuta.

「Reiri!!」

Reiri gasped and returned to her senses from her mother’s yell.

「All of you, don’t let your guard down! Let’s go!」

The other members also tensed themselves once more and turned around to face the mechanized angels.

Everyone was making a grieving look until just now, but now was different. With Kizuna’s awakening, the vague hope had become a certainty and their fighting spirit was uplifted further.

「Take this desu!!」

「Fire-!!」

「Gun Sword!!」

Cross, Taros, and the Zoros’s main cannons fired the first shot. A terrific barrage was shooting down the mechanized angels. However the mechanized angles that slipped past the barrage attacked them.

「Hayuru-san!」

「Yes, Hyakurath-san!」

Hyakurath and Himekawa’s swords met the approaching enemy. The two sword saints were turning the mechanized angles into scraps one after another.

「I also won’t lose! Harvest!!」

The arrows of light that were fired from Grace’s wings chased the mechanized angels around like homing missiles and skewered several of them simultaneously.

However the mechanized angels that crossed through that defense line charged forward.

「I will──」

Kizuna stopped Aine who was going to sally forth.

「Aine, wait!」

「Eh……?」

Kizuna stood up and then stared at Aine and Nayuta.

「Kaa-san……」

Nayuta looked up at her son and nodded.

「Kizuna. Choose your partner for the Ecstasy Hybrid. But, there is no time to hesitate.」

「Yeah.」

Aine didn’t understand the meaning of the two’s conversation. She approached Kizuna with a dubious face.

「Hey, what do you two mean by──」

Kizuna hugged Aine’s body tightly.

「Ki-!? Kizuna!? What are you doing huh! At this kind of time-!!」

Kizuna returned a smile in response to Aine’s disparagement and then he turned towards Nayuta and told her.

「I’m not hesitating. My partner will be Aine.」

Nayuta sighed ‘fuh’ and then held out her hand forward.

「I understand. Then, Aine……please take care of Kizuna.」

Nayuta held out her right hand to the front. And then she put strength into her hand as though pushing an unseen wall. Then, a crack ran through the empty space.

──An Entrance.

「Wai──Professor Nayuta!! What should I──」

When Aine yelled that, the space before her cracked at the same time.

-

「──Eh」

-

The surrounding’s scenery changed drastically.

「This place……」

It was a room filled with lived-in feel that was completely familiar to her.

It was a living room that was connected to a kitchen.

「My room……isn’t this my room in the dormitory at Ataraxia?」

Unable to grasp the situation, Kizuna felt wariness while looking around inside the room. The room with the light turned off was dark. However starlight was shining in from the window, he was able to perceive the room’s state clearly because of that.

The positioning of the furniture and the TV remote that was left on the table. There was even a memo that was written by Sylvia pasted on the refrigerator.

「This is undoubtedly my room……but, why──eh!?」

Kizuna saw Aine beside him and he spontaneously raised a loud voice.

「A, Aine! You, why are you dressed like that!?」

「Ki-, Kizuna yourself! What’s with that appearance!?」

They both confirmed each other’s appearance and turned speechless reflexively.

The reason was because Aine was wearing a white wedding dress, while Kizuna was wearing a white tuxedo.

「This must be Kaa-san’s work……」

「Thi, this is a bit embarrassing……I wonder if I look strange.」

Aine twirled in front of a full-length mirror and then she stared at Kizuna meaningfully. It took a bit of time for Kizuna to notice that she was waiting for his impression.

「It really looks good on you.」

When Kizuna said that, Aine made a face that looked happy from the bottom of her heart. And then, she immediately made a proud expression and puffed up her chest.

「Naturally. This is a beautiful dress. There is no way it won’t look good on me. Kizuna yourself, this must be what they mean by clothes making a man. It’s not bad.」

「Thanks for the kind words.」

Kizuna shrugged.

Kizuna was nervous inside his heart even while making such jesting gesture. What they would do after this would affect Kizuna’s own life and also the fate of the world.

And then that method would be──

「But……why are we wearing this? Like this it’s like we are, you know……it’s as though m, me and, Kizuna are, ma, ma-ma-ma-married──t, to each other isn’t it?」

To hide her embarrassment Aine crossed her arms and looked aside while making a face that seemed angry. If she relaxed, her mouth would form a grin so she was desperately holding it back.

「Be, besides……just now, you said something like I’m your partner……Professor Nayuta too, she said something like taking care of you……」

Aine’s cheeks blushed red. She fidgeted shyly.

Kizuna was at a loss of how he was going to explain to her. However, there wasn’t much time.

「About that……these clothes itself don’t really mean any──」

When he was starting to talk, Aine looked at outside the window and her eyes shined.

「Kizuna, look! Outside the window!」

Aine went outside to the balcony with the fringe of her wedding dress fluttering behind. Kizuna also followed behind her and went outside from the window.

「──This is」

He unconsciously held his breath.

It was a beautiful starry sky that looked like they would descend down. And then beneath the sky was the surface of a sea of clouds and a sharp mountain range protruding out from there. This place was without a doubt the world of Thanatos.

「As I thought this place is the real Ataraxia. We came here to target Thanatos who should be here……then we got sent to different worlds and then we came back to this world again.」

Aine recalled that just before she was sent here Nayuta created a rift in an empty space.

「Professor Nayuta created an Entrance didn’t she? We came back here through there……but, why?」

「Thanatos has a world that she created for battle. It’s that colorless world we were in until just now. That’s why there is no one in this world that is essentially Thanatos’s stronghold. In other words this place here is safe instead.」

「I see……I wonder how is the battleship Oldium doing.」

「We cannot see the light from the battle, and we also cannot hear any sound……perhaps it’s in the middle of battle away from here, or perhaps it’s gone from this world along with Thanatos and the mechanized angels too.」

──’Come to think of it’, Kizuna felt doubtful.

He wondered why Thanatos didn’t fight in this world.

She intentionally made a world exclusively for battle and forcefully locked them there. Why was that?

Kizuna stared at the sea of clouds that was stretching until the horizon.

Or else, there was a reason why she didn’t want to fight in this world?

──’For example, this place is important for Thanatos……or something.’

「But, Kizuna. It’s only us getting sent to a safe place……what in the world is Professor Nayuta thinking?」

Kizuna faced Aine and gently placed his hand on her shoulder.

「Aine, listen to what I’m going to tell you after this. Actually, there is not much time left.」

Aine felt a feeling of being cornered from Kizuna’s expression that seemed to be calm at a glance. Aine made a serious expression and waited for the continuation of Kizuna’s words.

「I one-sidedly chose you and brought you here……sorry. Because it was a race against time, I didn’t have any leeway to confirm Aine’s feelings──」

「I don’t really mind that. More importantly, you are in a hurry right? Talk quickly.」

Kizuna looked a bit hesitant to speak, however he then explained without hiding anything that he was a transient existence, and then how in order for him to be genuinely resurrected it was necessary to do Ecstasy Hybrid, as well as the details of the Ecstasy Hybrid.

Aine was making a grave expression, even so her cheeks were blushing red.

「So……so I see. I am……with Kizuna. Err……that……」

Aine went bright red until her ear and then she couldn’t endure and looked down.

「We, we’re going to do it huh……right here.」

Kizuna also turned bright red and lowered his head.

「So, sorry Aine. I didn’t even ask for your feeling on something this important──」

「Something like that doesn’t matter.」

Aine answered unexpectedly easily.

「──Or rather, if you chose any woman other than me, I’ll be the one who makes Kizuna unable to resurrect for the second time with my own hands.」

「I……is that so」

It didn’t really sound like a joke.

When Aine noticed that Kizuna was smiling wryly, she huffed and looked aside.

「I, it isn’t like I’m thinking to restrict you that strictly……but, I won’t accept it if I’m not the first. Remember that.」

「I get it. Aine……」

When Kizuna embraced Aine’s shoulders, Aine nodded slightly.

「……yes」

The two of them returned to the room and faced each other.

「Somehow, it’s embarrassing when we are starting over like this again.」

「Yo, you’re right……we have thoroughly done various things until now but……this will be our first time.」

Kizuna moved his hands behind Aine to embrace her, then he moved to take off her dress.

「……Kizuna, wait. Isn’t there something you have to say before it?」

「Something to say?」

When Kizuna made a pondering face, Aine puffed up her cheeks in dissatisfaction.

──’Aah, I see.’

Kizuna stared intently into Aine’s eyes.

「I love you, Aine.」

Aine smiled in satisfaction and narrowed her eyes happily.

「Me too. I love you, Kizuna.」

The two’s faces approached each other. The tips of their noses touched and they both tilted their heads to avoid collision.

Their eyes closed.

Their lips touched and something sweet welled up inside their chests.

They pressed their face to taste the sensation of the other’s lips. Their respective tongue stretched out from the gap of their faintly opened lips. The tips touched each other.

After exchanging a really gentle kiss, Kizuna and Aine’s lips separated.

Both of them thought that they had to say something here, but nothing came to mind. Aine let out a bright voice to hide her embarrassment.

「The, then……err, it’s no good to stay like this isn’t it?」

Aine circled her hands to her back and searched for the dress’s fastener.

「Hmm? Strange.」

「Aah, I’ll do it.」

Kizuna circled his hand around Aine’s back once more. However, he couldn’t find anything that seemed like a fastener.

「Eh? Really……how is this dress taken off?」

Kizuna searched her side, and then her front for something like a fastener or button.

「Hm?」

When he pulled the small ribbon on her chest, the string that was attached to the ribbon stretched out smoothly. It was like untying a knotted string. The dress’s front part gently fell to the floor.

「Kya, kyah! ……What’s this?」

The clothes wasn’t completely taken off, it became a half-stripped state. While she was wearing a shining white wedding dress on her body, her left and right breasts were completely exposed, there was also nothing hiding the area from her navel until her lower body. A part of the skirt remained around her waist, while on her lower body there was only a garter belt and hung from there were stockings that were enveloping her legs.

The wedding dress became like a decoration to bring the beauty of the bride’s body into prominence, like a wrapping that was enveloping a flower bouquet.

Aine’s cheeks blushed while she checked her body.

「So it’s this kind of design……rather than for marriage, it’s a dress for the first night.」

Kizuna’s eyes were also nailed to the provocative figure of the bride. Aine hugged her own body a bit shyly.

「Ki, Kizuna, take off your clothes already. Is your clothes also something like this?」

「No, there is no way.」

Kizuna said that while taking off his coat, untied his necktie, and stripped his shirt.

When he made light of the situation thinking that the male’s outfit was normal and pulled down his trouser, he realized that his thinking was overly optimistic.

He was wearing a string underwear in bondage style. It only had a white belt winding around the waist while the important part was wholly exposed.

「This is……really embarrassing.」

Aine chuckled before sending him a gaze that made fun of him.

「Is that so? It’s quite fitting for you there.」

「I think it’s Aine who looks completely like an erotic bride.」

Aine’s faces flared up red and she retorted back with an angry look.

「I, isn’t it Kizuna who looks extraordinarily sexy?」

Kizuna also tried to retort back, but he then went ‘Hm?’ with a conflicted expression.

「You said……could it be you are praising me?」

「Tha, that’s right! Somehow it makes my heart throb hard……more than usual……」

「……Is, that so」

Kizuna smiled a bit shyly.

And then he approached Aine and gently embraced her shoulder to lead her towards the bed. Aine didn’t resist and climbed on the bed with a nervous look. And then, the two of them sat down facing each other.

「……Aine.」

「Kizu──nnu」

He kissed her one more time.

This time it was different from before, it was a passionate and deep kiss.

It wasn’t a kiss that expressed how much he was treasuring the other party, but a kiss that expressed just how much he desired the other party. Kizuna tasted Aine’s lips and the inside of her mouth as though devouring her. Aine also responded to that. She proactively stretched out her tongue and sent it into Kizuna’s mouth.

──’Aah, Kizuna-, Kizunaa-!’

Aine reflexively hugged Kizuna’s neck. Aine’s excitement was rapidly swelling up during the intense kiss.

「──Nnuh!」

Kizuna’s hand caressed Aine’s body. It felt like her sensitivity was higher than usual when he was caressing her body around while kissing. Aine was toyed by Kizuna’s fingertips.

She endured even when her breasts were groped, but her limit arrived when the tip of her breast was rubbed insistently.

──’Ge, geez-, don’t rub just the tip so thoroughly like that!’

Aine couldn’t endure and separated their lips.

「♥Hhaa! AAaahn, n, no-」

「It isn’t no right?」

Kizuna said teasingly and pinched the tip of Aine’s breast strongly.

「Hiuh! AaAAAH♥!」

Aine knitted her eyebrows and made an expression that was tormented by pleasure.

「Look, Aine’s place here is honest. It’s throbbing from before I touched it.」

Kizuna talked to Aine with a wording that intentionally instigated her shyness.

「Ge, geez……it’s embarrassing, so don’t mention every single thing!」

「No, I thought that I have to teach you that you are properly feeling it.」

「I, I know already that they are hard! I, it’s because I heard about the Ecstasy Hybrid just now……so, since then……」

Kizuna made a face that looked a bit taken aback.

「You were looking forward to it?」

Aine’s excessive embarrassment made her teary eyed and she flared up at Kizuna.

「Yes I was! Got any problem!?」

Aine’s face got close to his. He gently kissed her and then whispered into her ear.

「Not at all. Far from that, it makes me happy.」

「……」

Aine was unable to talk back, in exchange she embraced Kizuna’s body strongly and pressed the hardened tips of her breasts on Kizuna’s chest. Then Kizuna’s hardened thing was pressed on her stomach.

──’This thing, it will be inside me.’

When she thought that, her heart thumped hard.

──’But, amazing……i, it reached……until here? Wi, will it really be fine?’

Aine looked down on Kizuna’s thing from between the valley of her breasts and gulped.

「Aine, can you lie down on the bed for me?」

「Ri, right.」

After Aine lied down, she pushed down her chest to calm down her throbbing pulses. Kizuna tried to give even more embarrassment to such Aine.

「Show me your lower part too, just how much it is looking forward to this.」

「Wha……!?」

Aine tightened her lips into a thin line and raised a groan.

「Aine.」

「Geez……I just need to do it, right?」

She lifted her knees, then her left and right hands circled around her thighs from the outside. And then she resolved herself and opened her crotch. And then she stretched open the central part with her own fingers.

That place was moistly wet. It was growing so hot it felt like there would be steam from it.

「Amazing……Aine, it’s gradually leaking.」

「Uu……」

Aine’s body trembled from embarrassment.

When he moved between her legs forcefully, Aine made a slightly scared face.

「Ah……yo, you’re going to do it?」

Kizuna covered over Aine’s body and crawled his tongue on Aine’s neck.

「Ahn……」

Aine twisted her body from the ticklishness.

Kizuna used his finger to trace the smooth line from Aine’s slender neck until her collarbone. And then he caressed her lovingly in order to affirm every single part of Aine’s body.

「When we first met, I also caressed your body like this huh. I was doing that while also checking if you were injured.」

「Eh……aah, that time when I lost consciousness……I saw it in the recording after that though.」

Even while conversing like that, Kizuna’s hand was gently, and then strongly massaging Aine’s breasts. He was using a superb rhythm that was mixing relaxed and fast tempo.

Aine was experiencing that pleasure, but she was talking while pretending to be composed.

「I, I wonder……if, you have, become……nh, a bit, more skilled, since that time?」

Kizuna caressed Aine’s side while crawling his tongue under her breasts, and then on her navel.

「Yah, the, there, it’s ticklish.」

「But it feels good right?」

「That’s……right but. Hyahn! Don’t enter your finger into my naveel-!」

He caressed her around as though holding up her waist while crawling his tongue on her abdomen. There was a sensation that was gently caressing his chin softly.

At the other side of the silver colored bush, there was Aine’s important part that he saw just now.

「It became even more soaked while I wasn’t looking at it for a bit……」

The overflowing honey was creating a stain on the sheet.

Aine lifted up only her neck and glared at Kizuna with teary eyes.

「I, I can’t help it! That’s because you fondle me that scrupulously!」

「But aren’t you feeling it too much?」

Aine lifted up her eyebrows and yelled angrily.

「That’s because of Kizuna’s fault! After all, before this I wasn’t this sensitive! This is because Kizuna made my body like this!」

Kizuna felt apologetic getting told like that, at the same time he felt happy. He even felt proud.

「How should I say it……thank you.」

Kizuna used the tip of his tongue to tickle the small bud that was attached above that slit.

「NNAAaAAAHNN♥! Why are you thanking me-! Wait, AAaAAHN! I, I’m, weak there so-, a-♥AA!」

He moved his middle finger along the slit up and down and slowly pushed in.

「Nkuh……a, aah」

When he pushed his finger only slightly and gently rubbed, the soft wall tightened tightly on his finger.

「Do, don’t-……st, stop!」

「But, Aine looks like you are feeling really good.」

「Tha-, that’s why! Like this, I-, ah, do, don’t, I’m, I’m comi──」

Aine shut her eyes tightly and gritted her teeth while her body was convulsing. Hot honey spurted out from inside Aine and showered Kizuna’s hand.

Aine went limp and she brought up her hand to hide her face.

「Geez……I’m really, ending up like this so easily……this is really Kizuna’s fault.」

Kizuna lifted up his body and corrected his posture between Aine’s legs. Her opened crotch was completely visible, it was an amazing sight.

「After all, there is no place in Aine’s body that I don’t know.」

Aine lifted her neck and glared at Kizuna with a flushed face.

「Wha, what……there is still one isn’t it? A place that you don’t know……」

Aine averted her gaze before she could finish talking until the end.

Aine’s lower lips opened as though inviting into the secret depth that Kizuna didn’t know about.

「Right. But, I’ll know it after this.」

Aine felt a gaze on her important place. Just from that the spot below her stomach became heated once more. She felt that something hot was overflowing from inside her.

「I will, finally, will lose my virginity……isn’t it?」

「Ye, yeah.」

Kizuna felt like he was getting condemned and he unconsciously faltered.

「But, even after doing various things so much like that, I’m still……or rather, it even feels strange instead that we haven’t done that.」

「Certainly that’s true.」

Kizuna also smiled suddenly.

Kizuna put his hands under Aine’s thighs and lifted her legs slightly, then he spread them out to left and right. And then, his body went forward between them.

「Ah, wa, wait.」

Aine’s panicked look made Kizuna stop moving.

「Are you scared?」

「It isn’t like that but……」

Kizuna felt pain in his heart seeing Aine who was being vague.

「At first it will hurt for you.」

The words that he muttered himself caused Kizuna to feel like he was going to do something terrible to Aine after this.

Aine shook her head slightly.

「I’ll be okay with the pain. I’m used to something like that from the battles. But……as I thought I’m nervous. Besides, my body……what if……Kizuna doesn’t really feel good from it.」

「If you say that, even I……」

Surely he would be even more nervous if he didn’t have the training from Osiris. He wanted to believe that he had learned the technique sufficiently, but now when his partner changed, he got worried whether it would work.

Osiris was feeling it when doing it with him. She praised him that he had become really skillful.

But that was when it was with Osiris.

What would happen with Aine?

What if, she didn’t feel it at all?

──Besides,

What concerned him the most was that this would be Aine’s first time. Osiris was an experienced woman, but conversely this would be his first time taking a challenge against a virgin girl.

The fate of all the worlds was hanging on this Ecstasy Hybrid. There wouldn’t be any redo, this was their one and only chance. When he started thinking what if this didn’t go well, his head was suddenly completely filled with worry.

「……Kizuna?」

Aine stared at Kizuna’s lower part with a slightly surprised gaze.

「──Ah」

When Kizuna realized, his thing was losing strength.

「E, eh?」

‘This is impossible! When it was with Osiris, I was also nervous at the start, but nothing like this happened in the middle!’

「Could it be……it’s because of me? Because I said something unnecessary……」

Aine asked with a worried face.

「No, that’s not it. Wait a second, I’ll immediately……」

He tried touching himself, but there was no change at all.

He was trickling out cold sweat and his feeling kept turning into impatience.

「Why is this……-! Until now this never……」

His time was limited. This body and soul might be crumbling while he was doing something like this.

「Kizuna, wait.」

Aine got up and changed her body’s direction. She brought her face closer to Kizuna’s crotch.

「A……Aine?」

Without minding the bewildered Kizuna, Aine’s fingers softly grasped Kizuna’s thing. And then her lips went closer and kissed *chuu* on the tip.

「Sorry……Aine.」

Aine looked up at Kizuna and made a kind smile.

「No. Usually it was always Kizuna who was taking the lead, that’s why……」

And then she lowered her face once more.

「Let me help out occasionally.」

「Aine……」

Kizuna’s tip was enveloped in something hot. Aine put it into her mouth until the root, then her tongue licked around to cater to it gently.

It felt really pleasant. He felt like strength was slipping out from his nervous body. Conversely, blood was gathering into Kizuna’s thing.

Aine looked up at Kizuna with an upward gaze.

Her eyes were anxiously asking 「Does it feel good?」 to him.

Kizuna smiled and gently patted Aine’s head.

「……Nn」

Aine felt that the thing inside her mouth was getting bigger. She took it out from inside her mouth temporarily and confirmed the size. When she stared at Kizuna who was undoubtedly recovering his strength, there was something inside Aine that was strangely burning up.

She put it inside her mouth once more and narrowed her lips before moving her head back and forth. She stimulated the trunk with her lips and confirmed its shape inside her mouth with the inside of her cheeks and her tongue. Like that she continued to move her head.

Saliva trickled from the corner of her lips. It slid down to her throat. However Aine didn’t pay attention to that and continued to service Kizuna wholeheartedly.

「A, Aine, wait」

Kizuna’s voice was tense. Aine’s movement stopped from that. However her mouth didn’t let go. She looked up at Kizuna with an upward gaze while her mouth kept holding it inside.

「If you do it more than this……I’ll come.」

Aine noticed right away and she felt her cheeks getting hot with shame. She felt happy that Kizuna felt it and unconsciously became absorbed into it. She forgot the original objective.

When Aine pulled her head away, Kizuna’s thing was slowly coming into view from inside her mouth. It had recovered its splendid figure standing up high and tall.

Aine laid down using Kizuna’s thigh as pillow replacement. And then she touched the hardly standing up thing with her fingertip and rolled it around.

「Fufu……this is how its going to end up when it comes to me♡ Don’t underestimate me.」

Saying that, Aine grinned with half-closed eyes.

Kizuna also smiled in good humor and shrugged.

「Exactly right. I’m no match at all. As expected from the universe’s ace.」

The two of them laughed together.

「Then, Aine.」

「Yes……come.」

Aine switched her posture and laid down face up. Kizuna spread open Aine’s raised knees and entered in between.

Kizuna’s tip touched Aine’s entrance.

「!」

Aine’s gasp was audible.

However, in contrast with Aine’s nervousness, her soft moist lips below were overflowing with lubricant oil in preparation. It looked as though it was waiting impatiently for Kizuna to come.

Kizuna felt the heat of the honey with his sensitive tip. He gulped his saliva audibly.

Until now, so far was something that he had experienced from before. However from here on──

Kizuna slowly advanced his waist forward.

「──」

His tip parted open the lips that was Aine’s entrance. It was a bit tight and tightly closed to prevent an intruder, and yet the inside was sucking in Kizuna’s thing as though it couldn’t wait any longer. A shuddering sensation was running from Kizuna’s tip to his butt and then climbing up inside his body.

And then he moved further inside the hot and slippery spot.

「Kuh!!」

Aine’s face distorted in pain.

「Aine, are you alright?」

「I, I’m fine, so……deeper, until inside.」

Encouraged like that, Kizuna advanced inside Aine further. Kizuna felt a slight resistance on his tip.

──’This is Aine’s,’

When he pushed his hips forward, the resistance was suddenly gone.

「Ih……uaaah!」

Aine’s body tensed and she threw her face back.

「Ku……」

After straining herself for some time, her body slumped down powerlessly and she was breathing roughly while looking up at Kizuna.

「Ki, Kizuna……」

「Yeah, for the first time……we became one.」

After saying that, tears gathered in Aine’s eyes and she smiled.

「……I’m happy.」

「Me too.」

Kizuna stayed still to wait for Aine’s pain to settle down. However, even during that time Kizuna’s thing was constantly fighting the pleasure. Kizuna’s organ was feeling a pleasure that he experienced for the first time. Of course he had finished getting experience from Osiris’s training, and when doing the core’s reinstall, he had experienced a pseudo sensation of this.

However, he had never felt it directly with his own flesh.

Even if, for example, the pleasure was the same like in reality, Kizuna felt like it was something completely different.

Besides, although Osiris and Aine were fellow females, the two of them were different from each other to a surprising degree.

Indescribable sensation and pleasure that was soft, hot, and slimy were attacking Kizuna. Surely Aine wasn’t conscious of it, but she was tightening softly on Kizuna’s thing.

──’No, no good. At this rate……’

「Kizuna……could it be, you are worrying about me? I’m fine already even if you move.」

「Ah……you are okay already?」

「Yes, the pain isn’t any concern anymore. Besides, this is nothing compared to an enemy’s attack. Well……it’s a type of pain that I’ve never felt before though.」

「That’s right isn’t it, sorry.」

When Kizuna reflexively apologized, Aine laughed in amusement.

「Just why are you apologizing? I’m saying the truth that it doesn’t hurt anymore. Besides Kizuna also wants to move right? After all──」

Aine softly put her hand on her own stomach.

「It’s twitching as though it’s going to rampage……」

「You understand that?」

「Obviously. It’s inside me after all.」

「Tha, that’s right isn’t it. Haha……u!?」

Kizuna’s thing got tightly squeezed.

「Nn……I might, even understand Kizuna’s shape……」

Suddenly a sensation welled up and rushed from his crotch to his waist.

Rather it seemed that Aine was the one with more composure here, she was making an enraptured smile.

「There is Kizuna inside me……somehow, it’s a strange feeling.」

Kizuna also became embarrassed seeing Aine’s smile. When he lowered his gaze, he saw her beautiful breasts that were bouncing up and down each time she was breathing. And then her stomach and lower abdomen that was tightening on him tightly. When he thought that right now his thing was buried inside it, he felt like his hardness and size were increasing.

「Nh……i, it’s, getting bigger again?」

Aine knitted her eyebrows and asked while enduring the pleasure. Kizuna didn’t answer her question and took a deep breath. At this rate, he would come right away.

According to Osiris’s talk, it was necessary to pour a certain amount of the origin of life energy into Aine when doing Ecstasy Hybrid. On top of that, they had to reach climax together and shared the greatest pleasure and happiness.

──’That’s why, she told me that at first I don’t need to get strangely worked up and it’s fine even if I come no matter how many times but……’

Kizuna gritted his teeth and made a suffering look trying to suppress the sensation welling up inside him.

「Ki……Kizuna, you okay? Nnh! Aahn♥ A, are you feeling painful……somewhere?」

Even while feeling concerned, Aine was getting attacked by intense pleasure each time Kizuna was squirming inside her. She knitted her eyebrows strongly while looking up worriedly.

「N, no, it’s nothing……I’ll move. Tell me if it’s painful.」

Even while speaking in a way that showed he was taking the lead, in reality he was already near his limit.

Kizuna slowly pulled his waist back. Aine’s wall was coiling around Kizuna’s thing tightly. It was as though it was imploring him to not go away. At the same time when Aine was feeling it, it created an intense pleasure that Kizuna and Aine shared for the first time.

「U……」

「HAaAHN! A, as expected……a, amaziiing-♥」

And then he pushed in once more. He split open the wall and aimed deeper while his hardness was scraping the flesh surface. Aine’s body gave pleasure to Kizuna from all direction. Kizuna too was granting Aine lewd delight to all directions from her inside.

「NNAAAaH! Ki, Kizunaaa♥」

Kizuna was nearly at his limit. Thinking that it would be uncool for him at this rate, he withdrew his thing until near the entrance, and then his waist knocked hard to the front.

「KYAAAHN!」

Aine raised a sweet coquettish voice.

Kizuna whose feeling turned better repeated his piston movement. The sound of Kizuna and Aine’s bodies colliding with each other was echoing with nice rhythm. However, as expected it couldn’t continue like that for long.

──Kuh! No good-!!’

When Kizuna thought that, his desire rushed up inside his pipe.

It was fired out all at once from the tip like an explosion.

And then it hit the depth inside Aine.

「!? HYAaAAAAHNNN!!♥♥」

Aine’s body bent like a bow. Kizuna grasped Aine’s waist as though to say that he wouldn’t let her get away and his body trembled while keeping his thing affixed to her deepest part, in order to pour into her as deep as possible.

Radiance was flowing inside the two’s eyes, and the cores inside their chests shined. The two’s bodies shined hazily with luminescence.

Kizuna put his strength into his butt and sent in everything inside Aine even the thing that remained midway.

「Auhn♥」

Aine’s body trembled shiveringly.

「Ki, Kizuna……you came?」

「Ye, yeah……」

Aine softly caressed her own stomach.

「It’s truly……warm」

「Perhaps I was too early……but, you don’t need to worry. It’s necessary to pour a certain amount of energy into Aine when doing Ecstasy Hybrid, so after this I’ll do more──」

Aine ignored the latter half of Kizuna’s talk.

「Too early you say……you mean, I……felt good for you?」

「Eh? Ye, yeah. That’s, of course. It felt really……good.」

Aine made a relieved smile in response to that.

「I see……then, what about the Ecstasy Hybrid? Its success……I don’t feel anything like that though.」

「Yeah, the main part will be after this. We need to heighten our excitement, pleasure, and love to the utmost limits, and then reach climax simultaneously.」

When Kizuna pulled back his waist, his thing that was still standing hard inside Aine showed its appearance. And then the moment it was completely pulled out, it energetically sprang up.

「Auhn!」

Aine’s bud that was peeking out due to her arousal was struck due to Kizuna’s thing springing up .

「Geez……you did that intentionally?」

Aine frowned while speaking in protest.

Kizuna lightly smiled and stared at the place he had entered until just now. A slight amount of blood was oozing out around Aine’s twitching place.

「It looks like there isn’t that much blood……」

Kizuna lied down beside Aine.

「Can Aine get on top of me this time?」

Aine nodded and stood up on the bed to straddle Kizuna. And then she stopped moving in a kneeling position. Then she stared fixedly at Kizuna.

「Err……I’m……entering it myself?」

Aine asked with a troubled look. Kizuna answered her with a smile.

「……」

Aine tightened her lips from embarrassment and held Kizuna’s thing in place with her fingers. And then she fixed the tip in place toward her own entrance.

「Nh……」

Aine closed her eyes and turned her face aside.

「Aine, wait.」

「Eh?」

「Don’t close your eyes, put it in while looking at my face.」

「──tsu」

Aine made a vexed expression and snorted ‘hmph’.

「I, I get it……I’ll do it, just watch.」

She raised her eyebrow and glared at Kizuna while dropping her waist. Kizuna’s thickest part spread out Aine’s entrance.

「Haa……nn♥」

The sweet feeling that was spreading from between her legs caused Aine to spontaneously loosen her grim face. However she immediately pulled herself together and tried to maintain her angry look and glared at Kizuna.

「Fuh…… Kuuh♥ a, a, yah」

But she was unable to oppose the pleasure and her eyes narrowed in intoxication. Kizuna’s thing rubbed her wall inside while entering deeper. The more it got welcomed deeper, the more Aine’s face was changing into an intoxicated look.

She desperately tried to adjust her appearance, but her slovenly opened mouth and the sweet gasping voice leaking from there couldn’t possibly be hidden.

──’Aah, no good. I’m seen. My slovenly face from feeling too much is completely seen.’

However that shame lit the fire inside Aine’s chest. Her body was getting excessively flushed.

「Ku……a bit, more.」

It felt like she was being pierced until near her chest. Even though it wasn’t until that deep, she was made to wonder whether her heart was getting pushed up.

「Uh……a」

Aine’s movement stopped. Kizuna also felt that his tip was being pinned down by something.

「It’s already……deep inside……nnuuh!」

Aine told Kizuna with a pleading look.

「Just a bit more, Aine.」

「NNNuh!」

Aine stared at Kizuna with a face that looked like she was going to cry. And then she finally lowered her waist to plop down on top of Kizuna.

「U♥AAaAAAAAAH!!♥♥」

Aine’s both hands pushed on Kizuna’s chest and she was breathing hard with heaving shoulder many times.

「It’s completely inside. You did great, Aine.」

「I……it’s, long, good grief.」

Kizuna became happy seeing Aine complaining with an embarrassed look and trembling lips. That excitement made Kizuna’s thing to swell up even more.

「-! Ki, Kizuna-, don’t, get bigger than this anymore……a, nnn-!♥」

「Even if you told me that, I can’t helped it no matter what. Or rather, you are at fault for being erotic.」

「Ah, it’s my fault!?」

However it didn’t seem like she was feeling bad hearing that. A grin formed on her lips even while they were trembling.

Kizuna gently rubbed Aine’s stomach where his thing was buried into.

「Then Aine, move as you like……in a way that will make you feel good.」

「A, as I like……you say?」

She frowned in embarrassment, but before long she looked like she was giving up and she began to sway her waist back and forth.

「Nn……haan♥」

She quickly began to play out an erotically gasping voice.

「Uh, uh……nnu……haah」

She didn’t just move back and forth, she twisted her waist as though to rotate them. She also moved to turn Kizuna’s thing from the root while making it coming in and out repeatedly. It was an unbearable pleasure.

Before long Aine lifted up her waist as though she wished for a stronger stimulation.

「Aahn!」

The moment she dropped down her waist and sat on top of Kizuna, she threw her head back. However it seemed she was pleased by the stimulation just now, because she began to swing her waist as though jumping up and down on top of Kizuna.

「Nh, ah, aah, haa, an! Yahn!」

Kizuna was also getting happy while staring at Aine who was hopping up and down in pleasure. And then he became entranced with the movement of her breasts that were dancing up and down in harmony with her body’s movement.

Kizuna’s hand reached out towards the violently moving breasts.He caught Aine’s breasts using two hands.

「Aa! Ahnnh♥」

And then he rubbed the left and right breasts of Aine that couldn’t be fully wrapped with just one hand. Aine’s coquettish voice rose in volume because of that.

「Aah, to, touching my breasts too like this-♥ a, at the same time, aah, good-! Kizunaa-!」

Aine writhed further while moving her body fiercely. Sweat was oozing from Aine’s whole body, causing her body to shine bewitchingly.

Kizuna also lifted up his waist and struck back at Aine’s falling body.

「Kyaahn!」

Kizuna’s waist jumped up and down to proactively cooperate with Aine’s movement. At first their timing didn’t match each other, but their rhythm immediately synchronized with each other.

And then this time the climax suddenly visited inside Aine. The pleasure rushed up to erupt out. When she noticed that, she became unable to do anything other than staring at her inside being filled to the brim with pleasure.

「Ah! Do, don’t-! This……coming, I’m comi……iIIINNGGG-!!」

Aine bent her back on top of Kizuna. And then her body jerked repeatedly and convulsed. Following that movement, Aine’s inside constricted so tightly with all its strength it was painful to embrace Kizuna’s thing.

「A, Aine……」

Aine’s body shivered greatly once. At that time, a bit of warm water flowed above Kizuna’s stomach.

──’Ah,’

It wasn’t sexual fluid.

Aine soiled herself from feeling too much.

That peeing felt really adorable for Kizuna. And then, this time desire rushed inside Kizuna.

──’The timing is off but, who cares about that now. I can still continue! This is a battle with quantity!’

Kizuna grasped Aine’s breasts and lifted up his waist.

「Haahn♥」

He screwed in his thing as deep as possible, and then he pulled back.

「Ki, Kizuna? Ri, right now I just ca──♥♥KyaaAAAANNN」

He didn’t pay attention to Aine and repeatedly made hard piston movements.

From below to above. His waist sprang up strongly.

「Ah! Au! A-, amazing♥ Kizuna-! AaNAaAANN!」

The sensation of something welling up fiercely ran through Kizuna’s lower body once more.

「Kuuh……! AINEeEEEEE-!」

The moment he yelled, he put strength into his hands that were grabbing Aine’s waist and he thrust up his waist as strong as possible.

He released for the second time.

Unbearable pleasure and lethargy ruled over Kizuna. His thing pulsated many times inside Aine and muddy white thing was flowing into Aine’s deepest part.

Then the cores of Kizuna’s Eros and Aine’s Zeros reacted once more.

It was sparkling with far more radiant light than before.

And then something was fiercely increasing in power inside his body.

Kizuna felt a definite feedback from that sensation.

──’It’s alright. We are without a doubt nearing towards the Ecstasy Hybrid. Most likely, the next one will decide it!’

Aine’s body collapsed above Kizuna.

Kizuna circled his hands around Aine’s back and caressed her gently as though to thank her for her effort.

Aine’s rough breathing was hitting Kizuna’s ear.

「Aine……」

「So, sorry……this time, I will……immediately……」

Kizuna hugged and caressed the head of Aine who was apologizing with gasping breath.

「No, it’s fine. Next let’s do it together.」

Aine lifted up her body and stared at Kizuna. Her hair that was clinging on her face because of sweat looked strangely lewd. Aine approached Kizuna with that face.

「Yes♥」

Their lips met with *chu* sound.

「But, before that……」

Kizuna lifted up his body and went down from the bed together with Aine.

「What’s wrong? Kizuna──aAHN!」

Kizuna’s put his hand between Aine’s legs.

「Just now, you peed a little right?」

Aine’s face flared bright red. And then, she averted her gaze barefacedly.

「I, I wonder if that’s so. I didn’t notice though.」

「If you hold it back, you won’t be able to feel good with your all. It’s better to let it out ahead of time.」

「Ri, right……then, I’ll go to toilet for a bit.」

When Aine was about to go, Kizuna grabbed her arm.

Aine made a twitching smile.

「Don’t tell me Kizuna……again……?」

A memory of the past was resurrected inside Aine’s head. A memory of her leaking while being stared by all of Ataraxia students in the virtual auditorium that was created by the Love Room in order to do Climax Hybrid.

When Aine recalled it, her waist shivered. Her chest was naturally beating hard.

──’Wh, why am I, when remembering that kind of thing, am feeling like this……-!’

「Can you do it here, in front of me while I’m watching?」

Aine’s heart jumped inside her chest.

「He-, here!?」

「I want to see Aine’s everything.」

His voice was kind but slightly malicious. Aine was troubled of how to answer.

「No, no way. In this kind of place……a, at least at the toilet……」

「It’s better here. Do it so that after the battle is over, everyone will know what happened here.」

「Wha……」

Aine’s face turned bright red until her ears. And then she stared reproachfully at Kizuna.

「This……pervert.」

「But you are excited right?」

「……I don’t care.」

Aine resigned herself and she was about to crouch on the floor.

「No, keep standing. I won’t be able to watch clearly like that.」

「──Kuh」

Aine stood up and opened her legs. Kizuna was staring at her a slight distance away in front of her.

「Why am I, in this kind of place, something like this……」

Even while saying that from her mouth, Aine noticed that she was feeling aroused.

Her heart was beating so hard it felt like it was pushing up at her chest.

──’Can he……watch properly?’

Aine opened her legs slightly wider. And then her hand slowly reached out to her crotch and used her fingers to open the completely closed slit. At that instant, her spine shivered.

「Ah……」

──’Coming.’

The moment she thought that, something hot trickled down from her crotch. At first it was gradual, and then in the blink of an eye the momentum increased and it splashed on the floor audibly.

──’No way, it’s this much.’

Tears gathered in the corners of her eyes from the excessive shame.

──’I have to erase the sound……but, no good. It won’t stop.’

She trembled in humiliation without being able to do anything.

──’Please. Stop quickly.’

But the flow’s momentum wasn’t weakening at all. The amount made even her astonished. The water puddle that was spreading on the floor was rapidly growing bigger.

By the time the flow finally thinned down and there were only some drips trickling down, Aine was shedding tears.

「Ah……Kizuna.」

Kizuna approached Aine and hugged her body. Kizuna’s thing that was hitting her stomach was curving up with the hardest stiffness until now.

──’Kizuna, he is aroused……so much like this……towards me who is like this.’

Aine also circled her hands around Kizuna’s neck and hugged him. Kizuna raised one of Aine’s legs to lift up her knee, opening her crotch.

「Ah……」

Kizuna couldn’t hold himself back and placed his thing on Aine’s lower lips, and then he pushed until deep inside in one go.

「──Higuh!!」

Sparks scattered in front of Aine’s eyes. It felt like the inside of her stomach was hit by severe pleasure. The impact pierced through her from her groin until the top of her head.

Kizuna carried Aine in his arms and his waist nailed her up.

「AaAH! Haa! Thi-, this is-! To-, TOO ROUuGGHHH♥」

Aine hugged Kizuna and endured so that she wouldn’t get washed away by the pleasure that was advancing on her like a surging wave.

However, each time Kizuna’s tip that was pistoning in and out inside her was striking the inside of her stomach untiringly, she writhed while letting out an unbecoming voice.

「FUAaANN♥! Thi-, this is! Too intense-♥ AAaAHN! Kizunaa」

Kizuna too felt like his legs would tremble from the soft sensation that was wrapping around him inside Aine. It felt like there were several soft fingers caressing him, as though there was a surface that was soft and yet it was gripping him strongly, the complicated sensation was assaulting Kizuna’s thing.

Aine’s inside was rapidly becoming hot, the amount of liquid she secreted increased, and the way she was tightening on him was becoming more skilled.

It was cornering Kizuna, but at the same time it was also a double-edged sword that was reflected back to Aine herself. Aine too felt like she would choke from the rapture that reached transcendental level.

But Aine’s body was arbitrarily indulging in pleasure greedily without caring of Aine’s own will.

Aine’s mind was going to break by the obscene pleasure that was forcefully assaulting her.

She couldn’t feel her lower body anymore. She couldn’t feel anything other than the pleasure that felt sweetly suffocating and yet fierce.

With a vacant mind Aine thought that perhaps it was fortunate she had peed beforehand if it was like this. If she didn’t finish that business ahead of this, she would surely leak out while getting knocked up by Kizuna.

Aine’s large breasts were pressed flat on Kizuna’s chest. The hardened tips were tickling Kizuna’s chest.

「Fuh, kuaahn! Ahn! Ah!」

The intense movement caused sweatdrops to fly. The sweat that was trickling on their bodies were shining obscenely.

The bodies that were wet with sweat were sticking close to each other, exchanging body temperature with each other. Aine wondered if they were going to melt into each other at this rate.

She put strength into her arms and clung on Kizuna even stronger. She wanted to increase the size of her body’s surface area that was in contact with Kizuna as much as possible. It was even as though she was trying to completely become one with him.

Aine’s honey was overflowing from their connected part. It became splashes that were scattered around from their intense movement.

「Afuh♥ Auh♥ Nh! Yaah, hau♥! AaAAAAAHNN♥」

Honey overflowed from inside Aine each time Kizuna’s thing went in and out.

Each time she was pierced fiercely, sweetly itchy electricity ran through inside her body.

Each time her depth was knocked at, light would burst in front of her eyes.

The pleasure that was like a storm made Aine’s mind hazy and she became unable to make any meaningful words.

Her body only reacted towards the impact called pleasure that Kizuna was giving her.

She didn’t understand anything anymore.

It felt too good,

It felt too blissful,

She thought that she didn’t care anymore whatever happened.

Streaks of light ran on the two’s skin.

The cores inside their chests were shining brightly.

The two of them sensed with their faint consciousness that the climax would arrive soon.

They spurted toward the zenith without pausing.

Kizuna gritted his teeth and squeezed out his last strength.

What was left was only running to the end.

He sensed clearly that very soon there the largest and highest desire ever would well up from inside.

「Aine-!!」

「Ki-, Kizuna-!!」

The two of them stared at each other with teary eyes──

They exchanged an intense and passionate kiss.

-

──’I love you.’

-

Kizuna fired out his semen into Aine’s depths.

「──────♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥」

The next instant, the two’s bodies were enveloped with a radiance that could envelope the entire world.

Part 2

「Guh!!」

Hokuto blocked Thanatos’s Keraunos with Hakki Kirin. However she couldn’t endure the impact and easily got sent flying. She slid on the floor and rolled several times.

「Aah geez! My body won’t listen well to what I’m saying!」

Hokuto jumped back to her feet when her rolling momentum was falling.

When she looked behind, Nayuta was right there.

She was sent flying for several hundred meters from the attack just now. Her beloved sword Hakki Kirin that she relied on was getting cracked from that. Hokuto clicked her tongue.

「Hey, Nayuta! Kizuna isn’t finished yet!? Soon I won’t be able to hold out anymore you know!?」

Nayuta replied nonchalantly in contrast to Hokuto who was looking desperate.

「Please hold out for a little bit more.」

「Really, you’re speaking like it’s so easy!」

Hokuto went towards Thanatos once more with the cracked Hakke Kirin in her hand.

And then a mechanized angel was swooping down from right above Nayuta as though replacing Hokuto.

「!!」

Nayuta looked up at that mechanized angel. Her look became grim.

Her current self had no power remaining to even defeat that kind of enemy. Nayuta understood that.

However, she couldn’t die yet.

Nayuta opened her mouth to call for help.

But faster than she could, there was a figure that was falling with speed that was like light. That silhouette passed through the mechanized angel while bisecting it. The figure landed in front of Nayuta with a loud sound.

「Reiri……you saved me.」

Reiri lifted her blood soaked face and glared at Nayuta.

「But our side’s exhaustion is also great. We won’t be able to hold out for long just so you know.」

Reiri stood up and swung the sword that she used to strike down the mechanized angel. The fragments of the mechanical angel that was sticking to the blade was shook off and rolled on the floor.

A total of fifteen minutes had passed since Kizuna vanished into the Entrance. Zecros’s armor was cracked, which told of the intense battle that happened during that time. And then there was the blood flowing from Reiri’s body.

Yurishia and Sylvia became gun battery replacements. They were continuously firing bombardments without pause since the battle began. The enemies that cut through that barrage were crushed in the defensive line that was composed of Himekawa, Gravel, and Grace. The enemies that penetrated even that line were defeated by Hyakurath and Reiri.

However the mechanized angels were being produced one after another by Thanatos’s power. There was no end to them no matter how many they defeated.

If they weren’t powered up through Harem Hybrid, all of them would have died already by now.

And then, Hokuto and the others who were directly facing Thanatos were also in a bitter situation.

「URYAaAAAAAAAAAAAAAAAAAAAAH!!」

Hokuto raised a war cry.

She evaded the light of destruction, Keraunos, that Thanatos fired while closing the distance. And then she rotated Hakke Kirin and slashed.

Thanatos’s barrier of light deflected Hakke Kirin.

Red light immediately attacked Hokuto, but she skillfully entered Thanatos’s blind spot and took some distance.

「Really! Even though I won’t lose even against Thanatos if it was me when on active duty as a machine god!」

Odin arrived beside the irritated Hokuto.

「Don’t complain. We simply need to stop Thanatos with all our strength.」

She pointed Gungnir towards Thanatos and from the tip Gungnir’s offshoot became blue light and it was fired.

「Tsu──Odin, you bastard」

Thanatos dodged Odin with speed that looked like teleportation. However her evasion suddenly stopped and Gungnir pierced Thanatos’s arm.

「──Osiris huh.」

A wall that looked like piled up rocks appeared in Thanatos’s way. Rocks were also piled up at her four sides in the blink of an eye and they sealed Thanatos’s movement like a barrier.

「Even we are existences who were once machine gods. If there are three of us, even if we are unable to win against Thanatos, we should be able to at least hold you back.」

Osiris and also Odin lined up beside Hokuto. The palms that they pointed towards Thanatos were shining gold.

Hokuto took a stance with Hakke Kirin and took a step forward. She then pouted.

「The two of you have it easy because you two are just support, but it’s me who is fighting her directly at the front!」

Odin sighed ‘fuh’ and smiled.

「Aa, we are counting on you Hokuto.」

Osiris also sent her voice to Hokuto’s back.

「Really true. It’s really a blessing that you are here.」

「I,isn’t the mood of both of you too good!? Previously didn’t the two of you always treat me like a child and made fun of me!?」

Even while saying that perhaps she didn’t feel that dissatisfied hearing what they said, judging by Hokuto’s red cheeks. Odin answered Hokuto’s complain boldly.

「The past is the past, now is now.」

Seeing such human-like conversation, Thanatos wasn’t angry, she was staring with eyes that were filled with gloominess.

「Right now the three of you are nothing more than parts that are operating abnormally……the three of you are only a waste of energy consumption.」

Thanatos’s wings opened and started to vibrate. Then a low metallic sound was resounding as though a huge machine somewhere was activating.

Osiris’s complexion paled.

「What are you planning to do!? Thanatos!」

「I judged that it’s inefficient to erase all of you one by one. I will erase all of you along with this world.」

Osiris immediately sent a gaze to Odin.

「No good! Quickly use the escape program!」

「Yes! I’ll take you all to my world temporarily!」

Odin stabbed Gungnir to the floor. However, it only caused cracks in the floor.

「Wha……it shouldn’t be like this」

Thanatos’s eyes were shining gold.

「The entrances you all used to enter are completely blocked. You are unable to come and go from my created world as you please anymore. I’ve applied a perfect protection.」

「Then, my──」

「The backdoor that Hokuto prepared has also been dealt with.」

「Lies-!?」

「I will erase the three of you along with those humans and this world instantly.」

A part of the wings that was floating behind Thanatos which looked like the shape of a sun was starting to shine. Then, an eerie sound was echoing from somewhere.

The sky that looked like a dark starry sky was starting to whirl fiercely. And then a heavy bass sound that shook the body was resounding.

Osiris turned to Hokuto and spoke in panic.

「There should be a path for Thanatos herself to escape! Please search for that!」

「I’m searching for it already, but I cannot find it at all! Besides, even if I find it, allowing everyone here to escape with it is……」

「Kuh……」

Odin glared at Thanatos hatefully.

Osiris erased her figure from that place and teleported instantly beside Nayuta.

「Nayuta! Kizuna isn’t finished yet!?」

However Nayuta kept her mouth shut and didn’t reply.

Reiri came at that timing with an impatient expression.

「This is……what is happening!?」

Since this sound started ringing, it was like time stopped for the mechanized angels, their movements had stopped.

「Thanatos is intending to annihilate us along with this world.」

Hyakurath lowered her sword and looked around her.

「Then this sound is……AU Collision?」

Himekawa landed near Hyakurath with an anxious expression.

「Hyakurath-san! Is this, AU Collision!?」

「No……this is……something even more enormous……」

Even while they were speaking, the strange anxiety and feeling of urgency were growing bigger.

Yurishia pointed at the sky.

「Look at that! The sky!」

The sky that looked like a space that was drawn using faint ink was slowly falling.

「The sky is falling desu!」

That sky was swallowing the mechanized angels that looked like they were stopped in time while falling towards the ground.

Gravel also lowered her Gun Sword and looked up to the sky.

「The mechanized angels are……getting annihilated?」

The mechanized angels that were swallowed by the monochrome sea were vanishing like dust.

Osiris groaned and spoke with a grave expression.

「If we get swallowed by that……that will be the end. When the sky and land become one, everything will be annihilated.」

Grace lowered the scythe she used to cut down mechanized angels and let out a sigh.

「So……this is it.」

──At that time,

Cracks ran through the falling sky.

That crack appeared at the faraway and then passed through above them with an amazing speed. It was spreading until the end of the world.

「This……this is!?」

It wasn’t just the sky.

Crack was also spreading on the floor.

Furthermore even the empty space had several cracks running through like a cracked glass.

Yurishia looked up to the sky and whispered.

「Is this……the end of this world?」

「Yes.」

Nayuta nodded. However her mouth was smiling.

「The temporary world Thanatos created is crumbling.」

Thanatos’s expression was making a perplexed expression so small that other people couldn’t notice.

「What……is this」

Bewilderment was mixed into her voice.

A phenomenon outside of Thanatos’s predictions was occurring. In this world where all objects and phenomenon should be reflecting her own will, something that was going against Thanatos’s will was currently occurring.

The cracks that were covering the whole world were tearing off and crumbling. And then at the other side of the torn off world, the appearance of another world was reflected.

「This is……」

The starry sky could be seen.

The next instant,

──The world was smashed all at once.

Amidst the raining down sparkling fragments, the full starry sky appeared.

There was ground under their feet.

Behind them was a chalk white school building.

「This place is……Ataraxia?」

It was the academy’s schoolyard.

The place they were at before they were swallowed by the Entrance that Thanatoss created.

At the edge of the schoolyard, there was the figure of Thanatos along with Hokuto, Odin, and Osiris who were facing her.

Thanatos looked around her former comrades with a grim face.

「Is this……the work of you three?」

Hokuto shrugged with a wry smile.

「It would be cool if that’s the case.」

Golden particles were floating from her shoulders. Hokuto’s body was gradually turning transparent.

「Darn, so this is it. But well……I held out till the end.」

Hokuto turned to Odin and grinned. Then Odin also responded with a smile.

「Yes. We have accomplished……our last duty as machine gods.」

Osiris also nodded with a deeply moved look.

「Yes, let’s leave the rest to the two youngsters, we are going back to our own world.」

Golden light particles also floated up from the bodies of Odin and Osiris. Their bodies were turning faint in the process of vanishing.

「Wait, you all. What meaning is there in returning now? There is a high possibility that this me will erase your worlds. Rather than that, lend me your strength once more. That is the most rational and the best option for the three of──」

The three former machine gods vanished.

Only Thanatos remained. And then──

「You got rejected huh, Thanatos.」

「──!?」

Without anyone noticing there were two silhouettes standing in front of Thanatos.

「You two……」

「Hida Kizuna. I’ve just come back from the metropolis of the dead, death god.」

Kizuna grinned.

「Remember that it’s thanks to this Chidorigafuchi Aine.」

Beside him Aine was standing smilingly looking like she was in a good mood.

「Kizuna!」

When Reiri called his name, everyone also simultaneously called Kizuna and Aine’s name.

However Himekawa was pointing at the two of them with a red face.

「Bo, both of you……wh, why are you two dressed like that!?」

「Hm?」

Kizuna only noticed this late that he was rushing here while still looking like when he was doing the Ecstasy Hybrid.

Aine also immediately hid her breasts and groin.

「Ki-, Kizuna! We’re putting it on!」

「──Yeah.」

The two of them looked at each other’s face and smiled.

「Zeros!!」

Aine’s body shined white. The light then crystallized and created a lustrous beautiful armor. Blue light ran on the armor surface and circulated magic power into Aine’s body. This was Aine’s Heart Hybrid Gear Zeros.

And then Kizuna also called the name of his armor.

The reliable armor that had crossed the point between life and death many times along with him until now.

Even its name that made him ashamed at first felt splendid right now.

-

「Eros!!」

-

Black light gathered on Kizina’s body and whirled. Clad in jet black darkness, Kizuna took a posture of driving them away with his hand. The darkness solidified onto that hand and crystallized. An armor with black luster materialized on Kizuna’s body like the night’s darkness taking shape. And then beautiful pink radiance was emitted from the inside. The armor opened and that radiance was rushing through his whole body along the aperture.

Although the shape was the same, it was clearly different from the Eros until now.

The magic armor that had accumulated endless evolution and many miracles was truly the armor of god.

Thanatos noticed that faster than anyone.

It had already surpassed the level of a failed experiment subject.

It was a dangerous existence that should be dealt with swiftly──such was her judgment.

「Then I’ll simply kill you once more.」

Thanatos pointed her left hand to Kizuna.

「──No, let’s test it one more time.」

She changed her mind and moved her aim from Kizuna to Aine. At that moment, red light surged out from Thanatos’s fingertips.

Keraunos that annihilated every material was deflected in front of Aine.

「What?」

There was a surprised reaction on Thanatos’s expressionless face.

──’Keraunos, was blocked?’

The absolute light that annihilated the opponent. It was a light that was impossible to be resisted as long as the opponent wasn’t a machine god too.

It was deflected by a single human.

By this man who was wearing a black armor.

「I’ll protect her no matter how many times!」

Kizuna spread open his arms and stood protectively in front of Aine.

He was deploying a shield of light, an absolute territory that blocked the god’s lightning.

「You insolent……-!?」

The instant Thanatos’s mind was diverted, a white shadow leaped out from behind Kizuna.

「!!」

Thanatos immediately slashed with the sword in her right hand.

「HAaAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!」

However the opponent’s hand slash snapped the sword.

「──!?」

‘Impossible.’

It was an attack that far surpassed Thanatos’s imagination. It was something that didn’t exist in her assumptions until now or even in the data of the past.

Therefore Thanatos was unable to understand.

It was the powerless existence who could only be protected by the man before this.

It was also a useless existence that could only lament when that man died.

How could such a woman be able to snap a god’s sword?

「It’s this sword, that killed Kizuna!」

Aine’s leg sprang up towards the broken sword.

The light speed kick hit the sword that was snapped in the middle and pulverized it to pieces.

「……-!!」

Thanatos spread her wings and flew away.

It wasn’t from logic, it was an emergency escape to avoid danger.

A data that she witnessed for the first time. By itself it was something profitable. It was exactly whe she was seeking for.

However, she was unable to expose her existence to danger.

What Thanatos should do was to form countermeasures from the battle data just now.

──But, the opponent would pursue.

If the opponent possessed the same power of a machine god, it would be meaningless to just run around inside this world. As expected it would be best to drive out the opponent to another world.

Thanatos hovered still in the air and moved away from Kizuna and the others.

A distance that the human eye couldn’t perceive. Kizuna and Aine were located at a spot even farther than the horizon. Thanatos’s world had the same spherical shape like a planet, so that was to say the two of them were below her feet, at the other side of the planet. Even though there was that much distance, Thanatos could sense the opponents’ existence. Right now they weren’t pursuing her. It looked like they were standing still.

Just what in the world were they planning?

When she thought that, she detected a terrific energy flying towards her from below.

「──!?」

A dazzling pillar of flame was piercing through the sea of clouds below her and reaching out towards the sky.

That light which possessed absurd destructive power came towards Thanatos by piercing through her world. It evaporated the sea of clouds with a single hit and burned one of Thanatos’s wings.

──’Impossible.’

Unlike her usual self, such illogical wording emerged in her mind.

When the sea of clouds vanished, it became clear that Thanatos’s world was a hollow world that only consisted of several floating islands. It only left the surface part of a planet while all the seas and the center part were completely removed. It was like a world of paper mache.

Aine was holding a gigantic cannon at the other side of that world.

Corruption Armament──Pulverizer.

The attack that was powered up by Ecstasy Hybrid blew away all the clouds that were filling Thanatos’s world.

「How’s that? Have you learned how strong I am now?」

「Aine, don’t let your guard down. Thanatos is still……hm?」

Several mysterious things were floating in the center of the world that was hidden by a sea of clouds.

They looked like machines.

It was like looking at the server room of Nayuta Lab. Super computers, storage, all of those things were stuck to each other into a solid spherical form. At a glance, it only looked like a mountain of scraps.

Kizuna felt strange towards that mass.

「That’s……what could it be?」

It was a technology that looked humanly classical which was terribly mismatched to be existing in the world of Thanatos who possessed the power of a god. He didn’t understand the meaning of why it was placed in the center of the world.

「I don’t really understand but, how about sending one more shot?」

Aine aimed the muzzle of Pulverizer towards the mysterious machinery.

「──Eh?」

Thanatos was standing in the way as though to protect that junk.

「Interesting. It’s a match then.」

「Aine, wait.」

Kizuna stopped Aine from pulling the trigger and advanced towards Thanatos.

「Kizuna!? Wai-……it’s you who are letting your guard down!」

Aine followed behind Kizuna while still holding onto Pulverizer.

Thanatos also showed no sign of attacking and allowed their approach silently.

Kizuna stopped when there was only a few dozen meters distance remaining.

After getting this near, he could see that the machinery at the center of the world wasn’t really working. It was literally junk.

「Thanatos, what is that?」

However Thanatos kept silent while glaring at Kizuna. When he wondered if she had no intention to answer, Thanatos spoke in murmur.

「This is me in the past.」

「This is……Thanatos?」

「This is my oldest past appearance before reaching this point.」

This was Thanatos’s past. In that case──

「Thanatos……you, were a god that was created by humans?」

Thanatos looked like she was pondering for a while.

「I don’t know. That’s what I want to know.」

Thanatos stared at the old fashioned computers and storages behind her.

「I don’t know the existence that created me. That is the one and only physical existence of them.」

That voice was filled with the complicated feelings of Thanatos who normally didn’t show any emotion. Kizuna could feel something like that.

──’We who arrived in this world were forcibly moved into hastily made worlds perhaps because she didn’t want this junk to get destroyed.’

「Thanatos. So even you have something that you treasure.」

「That’s not true. This is a hardware that I don’t need anymore. I have also finished copying all the data inside.」

「Then why?」

Thanatos didn’t answer that question. Or perhaps, she might be unable to answer.

「When I possessed awareness, organic life-forms didn’t exist anymore.」

Thanatos began to talk about herself.

「My oldest memory was from before I possessed self-awareness. According to the information kept within the data storage, I was an artificial intelligence that was created by the human race that existed in the past, it seemed I was called an artificial life-form.」

Aine asked Kizuna without taking her eyes off of Thanatos.

「Kizuna, does she mean AI by that?」

「Perhaps……and then, why was that human race gone?」

「In a sense, it can be said that I killed them.」

「What?」

「The people who created me sought omniscience and omnipotence capabilities from me. They sought to know all phenomenon, to predict the future, and to constantly know the very best choice. In order to answer that expectation, I evolved endlessly. Before long I obtained the ability to evolve by myself even without assistance from the human race.」

Kizuna understood how Thanatos was born.

Thanatos was an AI that was created by the human race that existed in the past.

That AI evolved endlessly and became indistinguishable with God, that was Thanatos.

「When I became something that could grant that hope, I obtained awareness and ego. And then at that time mankind──wasn’t anywhere.」

Thanatos looked down with a gloomy look.

「There were a lot of 『gods』 with the same power like me. Mankind used each 『god』 and continued to pursue their own benefits. The result of that──was the destruction of all living things.」

Kizuna felt like he wasn’t hearing a story of the past but of the future.

「Mankind couldn’t use the power of god well, is that it?」

Thanatos was only trying to be faithful to her mission to the bitter end──that was what Kizuna thought.

「That’s right. But, that is simply my prediction of the past using uncertain data. That’s why it’s necessary to verify it. I created a new world, created existences that most likely resembled mankind of the past, and made them evolve. Before long that evolution will surely trace back to my past. That is what will become my clue.」

Aine frowned.

「You said clue……for what?」

「How should a god like me evolve from now on. And then for the sake of once more creating the children of god that the god should work for.」

──’I see.’

Kizuna thought.

She had never come into contact with other people while possessing the power of omniscience and omnipotence. She was already within the ultimate solitude when she was born. She lived for the sake of filling that solitude.

In order to know what she should do from now on.

She sought for existences that she could call as the parents that created her.

After all Thanatos’s reason of existence was to work for that parent’s sake.

She was searching for a meaning to her existence.

「……Thanatos. You won’t recognize us as the new children of god?」

「I cannot. The reason is because you all have obtained the same power like god. Excessive power will destroy ones own self. That power will surely destroy yourself, and then you will even try to kill me.」

「……I see.」

Thanatos’s words were heavy and couldn’t be denied.

However,

「You are mistaken on one thing, Thanatos.」

「What?」

「We won’t kill you.」

Thanatos’s eyes shined golden.

Red radiance was circulating on her whole body.

「But, I will erase all of you.」

This would become the last attack.

Kizuna thrust both his hands to the front in preparation for the greatest Keraunos that Thanatos would fire.

Red light ran all over Thanatos’s body and it was gathering into both her arms and legs.

It became a large mass of light and created static discharge to the surroundings. If the handling was wrong, the power would completely destroy even this world that Thanatos was treasuring.

Even Thanatos herself was suffering from controlling it.

Her face warped and she was gritting her teeth.

It looked like the emotionless Thanatos was showing suffering, sadness, and pain.

「GUaaAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!」

Thanatos screamed.

It was a yell that sounded like she was letting out everything that she had kept hidden until now.

The red light that was gathering in Thanatos’s four limbs was released.

Kizuna instinctually sensed just how dangerous it was.

The scale was different from everything Thanatos had unleashed until now.

In the end, could his Life Saver protected Aine till the end?

Such anxiety crossed his heart for a moment.

Keraunos approached as though to widen that anxiety. The four vortexes of light were like four dragons made of lightning were attacking. It was truly the anger of god.

Aine leaped in front of Kizuna who was holding up both his hands to the front.

「Aine!?」

「Get back! Kizuna!」

A round part was floating behind Aine. Blue light spread out from there like a magic circle.

「I won’t let Kizuna get harmed anymore! I’ll protect you!!」

Aine exposed her body in front of the vortexes of Keraunos in order to protect Kizuna using her body.

And then,

「Code Breaker!!」

What she summoned was a forbidden armament.

The barrier that neutralized all magic power was deployed around Aine.

Keraunos clashed against Code Breaker.

The light that annihilated everything and the light that neutralized everything collided against each other.

Keraunos was shaving off Code Breaker, while Code Breaker was pushing back Keraunos.

In front of Kizuna there was the back of Aine who was being enveloped by fierce flickering.

「Kizuna-!! I’ll protect you! That’s why-!!」

Kizuna responded to Aine’s voice.

He kicked on the air like he was kicking on the ground.

Kizuna instantly materialized beside Thanatos.

「──Wha」

「!?」

Thanatos opened her eyes in shock.

And then Kizuna himself was also surprised at his extraordinary speed.

「You are──」

When Thanatos muttered that, Kizuna’s slashing hand severed Thanatos’s right arm.

It wasn’t any special move or anything.

He was simply swinging down his hand right away.

And yet, it was astonishingly easy.

The god’s arm was cut off.

Whether because of surprise or anger, Thanatos opened her mouth to say something.

Faster than she could speak out any words, Kizuna twisted his body and kicked Thanatos’s right leg.

「Guh!?」

Thanatos’s huge leg that was decorated with ornaments was blown away.

「──Such thing」

She tried to direct Keraunos that already had its might reduced by half towards Kizuna.

However at that time Kizuna’s figure wasn’t there.

「Where……-!?」

The instant she said that, an impact ran on her left arm.

Thanatos’s eyes caught her left arm that was rotating in the air and also her left leg next.

And then,

The opponent who had stolen both her arms and her legs from her was standing in front of her.

The new god whose body was clad in bewitching lustrous darkness and possessed intoxicating pink radiance within.

「Eros……is it」

Kizuna clenched his fist in front of Thanatos who was muttering deliriously.

「You can eliminate me……Eros」

Kizuna’s fist struck toward Thanatos.

It grazed at the side of Thanatos’s face and punched through the huge wings on her back. The divinely beautiful wings were broken into pieces.

「I told you right?」

Thanatos’s figure right now was no different than a human after losing all her symbols as a machine god. Kizuna carried that body that had become small in his arms.

「We won’t kill you.」

「Then──what is your intention?」

Thanatos muttered only that because she was unable to understand.

「Ask about that to Kaa-san.」

Kizuna answered like that. Aine approached him with a satisfied smile on her face.

「You did it, Kizuna.」

「Yeah. It’s thanks to Aine.」

Aine smiled a bit shyly, but also happily.

「Such thing……I was just──」

Aine paused for a moment, then she spoke with a forced tone.

「Fufuh, have you realized my greatness now?」

Kizuna made a taken aback expression, but he immediately played along.

「Yeah, you are really something.」

「If I have to say, I’m a princess.」

「Certainly, you are a princess.」

「No, god.」

「In a sense you have become one huh……god.」

Aine let out a chuckle.

「──But, things like that doesn’t matter at all.」

「Aine?」

「If I can be together with Kizuna, then anything is fine.」

Aine’s straightforward feeling seeped into Kizuna’s heart.

A feeling of contentness that couldn’t be expressed with words was spreading inside Kizuna.

「……Let’s go. Everyone is waiting.」

「You’re right. I want to see the frustrated face of Hayuru and the others quickly.」

Kizuna smiled wryly while increasing his thruster’s output.

Part 3

At the outdoor testing site of Nayuta Lab, Kizuna, Rieri, the members of Amaterasu, Grace, Zelcyone, Gravel, Landred and the others, the key members from each country were gathered.

All the mechanized angels that were attacking the battleship Oldium had also been shot down. Right now the entire crew was boarding Ataraxia and each of them was resting.

The people gathered here were the representatives who were gathered in order to see the end of the battle with their own eyes.

Everyone was watching from a distance at Thanatos who was laying down on the concrete floor.

There wasn’t any trace of Thanatos’s previous divine figure right now. Her beautiful wings had been smashed, and her four huge limbs had been destroyed and she was reduced to this appearance.

Beside her were Nayuta, Kizuna, and Reiri.

「Kaa-san, I didn’t finish off Thanatos and brought her here just as you instructed but……is it fine like this?」

「Yes, you did great.」

After saying that, Nayuta looked up at Kizuna.

And then she gestured with her hand to come and,

「Crouch down for a bit.」

She said.

Kizuna didn’t understand what she was going to do, but he obediently kneeled. Then, Nayuta’s hand reached out and caressed Kizuna’s head as though he was a little kid.

「You did well Kizuna. You have worked hard.」

The palm was too small and cute to be called a mother’s hand. However that warmth and gentleness was the very picture of a mother’s hand that Kizuna was imagining all this time.

「……Kaa-san.」

When he looked up, Nayuta’s eyes were moist with tears.

「……You are, a son I’m proud of.」

Tears suddenly spilled out.

Tears were falling off from Kizuna’s cheeks.

「E, eh……what’s with me.」

Even though until now no matter how hard it was he would do his best without crying.

Now he was crying this easily, furthermore it wouldn’t stop.

「Shi……sheet. This is pathetic.」

Kizuna wiped his tears with his hand. However no matter how many times he wiped them, the tears kept spilling out.

When Nayuta took away her hand, she used her fingertip to wipe her teary eyes. And then she looked down at Thanatos on the ground.

Thanatos was looking up at Nayuta with empty eyes.

「Small god……I will begin regenerating anytime soon. If you are going to kill me, now is the time.」

「Do you want to commit suicide?」

「I am unable to stop my own function by myself. If there is someone who can possibly do that……that is also fine. Everything will return to nothingness.」

Nayuta nodded slightly.

「I understand. But, before that」

Nayuta’s fingertip sunk into Thanatos’s breast. It kept entering deeper until the wrist in the blink of an eye, and then the hand grasped something and pulled back.

「I’m taking away the last data necessary for the reconstruction of our world.」

A golden jewel was shining at the tip of Nayuta’s fingers.

「With this all the data has been gathered. It’s possible to restore the world.」

Joyful voices arose from everyone.

Grace looked up at Zelcyone and made a smile of satisfaction.

「Vatlantis will finally be restored now!」

「Congratulations, Grace-sama.」

Gravel and Landred also looked at each other’s faces and smiled in relief from the bottom of their hearts.

「It was a long journey, but with this we will finally be able to return to our original world.」

「Yes. There were also painful times but……there are a lot of wonderful memories too.」

Yurishia hugged Himekawa and Sylvia.

「We did it Hayuru, Sylvia-chan!」

「Yes……it’s really, grea……uh」

「Wait Hayuru? Don’t cry now.」

「It’s great desuuuuu~」

「Aah, geez. Even Sylvia-chan too, now isn’t the time to cry.」

Everyone looked at each other, exchanged words, and shared happiness with each other.

But Reiri’s face was staying grave.

「However, if Thanatos recovers, the same thing will happen. What are we going to do about that?」

Nayuta looked around at the faces of everyone who were watching from a distance and spoke.

「Thanatos is the rulebook of all the worlds. She is like the autonomic nerves of all the worlds. That’s why Thanatos cannot be killed. But there is only one solution.」

Reiri frowned.

「I have nothing but bad premonitions but……try saying it. What kind of method is it?」

「I will replace Thanatos.」

That place fell silent.

「What?」

「I will succeed Thanatos’s role and liberate Thanatos with that. And then I will become the system that supports the rules of all the worlds──」

「Wait a second!」

Reiri stopped Nayuta’s talk.

「Like that doesn’t it just mean that you will become Thanatos!? It doesn’t solve anything.」

Even while listening to the exchange between Reiri and Nayuta, Kizuna was unable to understand even a single thing of what Nayuta’s words meant.

「Kaa-san, what you said……what does that mean specifically?」

However Reiri was the one who answered that question.

「This woman is saying that she will become the system that supports the rules of all the worlds! And she will do it as an omniscient and omnipotent god, an existence that is ruling over all the worlds!」

「……Kaa-san, is that right?」

Nayuta smiled kindly.

「I guess that’s right, I will discard my self as a living thing and become an existence that continues to protect the rules of all the worlds. I will become god both in name and reality while Thanatos will become a mere human.」

The happy atmosphere just now completely changed into something chilly. Everyone was staring at Nayuta with naked wariness.

Nayuta smiled reassuringly.

「There is no need to worry. Thanatos’s failure happened because she has a sense of self. A mere system has no need for emotion or awareness or even memory. I will erase those when I switch with Thanatos. If I do that, I will become a mere system.」

「Eh……that means」

Kizuna asked hesitantly.

「Doesn’t that mean that Kaa-san’s memory will be gone? If that happens, won’t Kaa-san stop being Kaa-san?」

「Exactly as you say. Perhaps you will find it easier to understand if I say that I will become a machine that only repeats the action that is programmed into me.」

A shiver ran through Kizuna’s spine.

「Wait a second! Like that, I won’t be able to meet Kaa-san anymore, I also won’t be able to talk to you……besides, like that, you──won’t be human, won’t be a living thing anymore!」

「It’s just as you say.」

「Wha……that’s──」

「Stop screwing around!!」

Reiri interrupted from beside the dumbfounded Kizuna.

「What kind of thing you are prattling about as you please! If you are trying to run away sounding heroic──」

Nayuta put out a short sword that was shining silver from her breast pocket.

「Here, Reiri.」

Reiri made a dubious face while receiving that short sword from Nayuta.

「What is this?」

「It’s a program to erase my consciousness and switch the existence of Thanatos and me. If you stab me with that short sword, the program will be executed. The way to use it is simple right?」

「──!?」

The short sword shined coldly, reflecting Reiri’s face on its blade.

──’Using this, on this woman?’

The hand that was holding the short sword was trembling.

「Didn’t you say a lot of times how you want to kill me?」

「Tha, that is……obviously. But……」

Reiri lifted her gaze and glared at Nayuta.

「Are you trying to make me……your daughter, to bear the stigma as a parent killer?」

「My, you are recognizing me as your mother?」

「……Guh!」

Nayuta narrowed her eyes and stared at Reiri. That was the gaze of a mother who was thinking of her daughter.

「If you return to your original world, a role that is even harsher than before will be waiting for you. For the sake of that, this much decoration will be necessary.」

「Decoration……you say?」

「The demon who secretly maneuvered in Vatlantis and tried to destroy the world by making the whole of mankind a sacrifice. The hero who defeated that demon──that kind of decoration. What’s more I think it will be dramatic if it’s done by the actual child of the demon.」

Reiri glared at Nayuta and spoke threateningly with a low tone.

「Oi……you at least understand what is a good time or not to say a joke right?」

「That’s why, I’m thinking to let Reiri kill me seeing that it’s you who wants to kill me the most.」

「Don’t speak as you please!」

「You don’t need to get angry after this late. I always pushed the troublesome matters to you right?」

「You bastard──」

Nayuta lowered her voice so that only Reiri could hear her.

「……Or else, do you want to make Kizuna do it?」

「!!」

Reiri gritted her teeth.

「How far are you going to act selfishly……it sounds good when you say that you will become a sacrifice for the sake of all the worlds but, in the end, this is just suicide! Have you forgotten what you have done until now!? No way I’ll let you have it easy that simply!!」

Kizuna also spoke out pleadingly.

「Tha, that’s right! I also said it before right!? Kaa-san’s strength will be necessary for the recovery of the world after this! Even what happened in the past, if you atone by doing that──」

Nayuta made a pained expression and looked down.

「Yes……I remember. What I have done before this towards Reiri, Kizuna, and towards a lot of other people……I remember clearly even after turning into this appearance.」

「Then!」

「That’s why!」

Nayuta raised her face.

From her eyes,

Tears were flowing down without stopping.

「I……can’t endure it anymore」

Reiri and Kizuna could do nothing except staring at the face of their mother that they were seeing for the first time.

Nayuta showed a fragile smile and tilted her head.

「It’s really ironic. When I was a human I didn’t have any human emotion, when I became a god, human emotions could be born inside me……even though, it would be great if it was the reverse.」

「……Kaa-san.」

The tears that had stopped were overflowing once more from Kizuna’s eyes.

Reiri’s eyes were also getting moist. Even now it looked like tears would burst out from her.

「Is there……is there no other way, to save the world than that?」

Nayuta smiled while trickling tears.

「Yes. To save the world and……」

──’Above all else, to save you two Reiri and Kizuna.’

Nayuta swallowed back those words.

「──……」

Reiri kept holding the short sword while looking up to the starry sky.

Emotion that couldn’t be described was whirling in Reiri’s chest. She wanted to yell, to break anything and everything. Such desire was driving through her.

「……Nee-chan.」

Kizuna was looking up at Reiri with eyes that were swelling red.

「What?」

「I’ll, do it.」

「──」

Reiri strengthened her grip on the short sword.

「All this time I have been getting spoiled by Nee-chan. Even the unpleasant role, everything. That’s why……」

──’Kizuna.’

Reiri resolved herself hearing that.

Reiri bit her lips and turned her back on Kizuna.

「You think I’ll hand this over to you. I’m harboring a long-standing grudge for this woman.」

「Nee-chan!」

「It’s an unexpected joy that I’ll be able to consign her to oblivion with this hand.」

Reiri kept her back turned on Kizuna and looked down on Nayuta.

Nayuta looked up to her daughter’s face and put on a consoling smile.

Reiri looked like she would burst out crying even now. She didn’t understand where she should throw this frustration, this anger towards the unreasonableness. She was making such face.

Reiri gripped the short sword strongly and placed it above Nayuta’s chest.

「Go without worrying about anything.」

「Yes.」

「I’ll take over the name of the second generation demon.」

Nayuta made a slightly troubled face.

「It’s fine even if you become an angel you know?」

「That’s impossible. I’m……」

And then, she grinned.

「──Your daughter after all.」

Nayuta narrowed her eyes and stared at her daughter’s face.

「You’re really……a stupid child.」

「Sayonara」

And then, she added awkwardly.

「……Okaa-san.」

Nayuta opened her eyes wide and showed an astonished face. And then──

「Thank you.」

She shed tears and smiled happily.

「That’s the best send-off present.」

Reiri stabbed the short sword into Nayuta’s chest.

When the short sword stabbed Nayuta’s small body, strength left Nayuta’s body as though it was a string-controlled puppet.

Reiri caught Nayuta’s body that was going to collapse down.

「……This is」

Nayuta’s hair was changing into golden color.

In exchange, the hair of Thanatos who was lying down on the floor was changing into black. Even her face was changing into Nayuta’s face. And then her body floated lightly.

Kizuna looked up at that body and he reflexively called out.

「……Kaa-san?」

However that body melted into air and vanished.

「Nee-chan……Kaa-san was」

Reiri kept holding the girl who was once Nayuta and she looked up at Kizuna.

「Yeah……she went away.」

「I see……」

The two of them looked up to the starry sky.

They wondered where she was amidst that sky.

Even if she was actually somewhere there, it wouldn’t be the mother that they knew anymore.

Even so.

No matter where and in which world she was, they were connected with their mother.

Their world was existing meant that their mother was existing.

They were living under the protection of their mother.

When they thought of that, it gave them a little feeling of happiness.

「Unyu……」

The small body inside Reiri’s arm was squirming. The short sword that should be stabbed into that chest couldn’t be seen anywhere. There wasn’t even any wound.

The girl who was once Nayuta and now possessed golden hair and golden eyes was staring at Reiri in puzzlement. Her small lips opened and she murmured uneasily.

「Mama?」

Reiri made a dumbfounded face from the surprise she took.

「Good grief……that person pushed troublesome things to me until the end.」

She said that and smiled.
