After eating lunch, Natsuya and Seiji had a discussion in her study.
âHow did you do it?â
Although Natsuya felt that it may be improper to pry, she was unable to restrain her curiosity and still asked it in the end.
It definitely was no easy matter to create oneâs own Yin-Yang Seal. Every Yin-Yang Master knew just how difficult it was, which was why Natsuya found Seijiâs situation truly incomprehensible. Perhaps it was a bit of an exaggeration to call Seiji a god or demon because of it, but having these types of thoughts were understandable.
âActually, I recalled my previous lifeâs memories.â Seiji pretended to be serious. âIn my previous life⌠I was Seimei Kamijou!â
Natsuya was rendered speechless.
The study fell silent for several seconds.
âHaha, I was just joking.â Seiji chuckled. âI donât really know how I did it myself, either.â
That was the truth. It was all taken care of by his system, and Seiji really had no idea what the process of creating a Yin-Yang Seal should have been like.
Natsuya didnât laugh at his joke. Instead, she continued staring at him.
âPerhaps that really is the caseâŚâ
âEh?â
âPerhaps you really are Seimei Kamiakiâs reincarnation,â the student council president stated with a serious expression.
This time, it was Seijiâs turn to be rendered speechless.
The study fell silent for another several seconds.
âCough⌠letâs discuss something else instead.â Seiji forcefully changed the topic in order to avoid the mysterious awkwardness he was feeling. âWhat do you feel now about us dueling together against Akatsuki Mitarai?â
Something flashed in Natsuyaâs eyes.
âYou became a Yin-Yang Master⌠this is an excellent ace up our sleeves. If we use this well, we can indeed defeat him.â
âI know, right? I said before that we can win.â
âThereâs still a great amount of risk, though. After all, you only became a Yin-Yang Master today, and youâre a complete newbie.â Natsuya folded her arms. âRather than dueling with him right away, I think that it would be much better to stall for time. After all, with your rate of growth, it probably wonât take long before youâre at a level where youâll surpass him completely.â
Seiji didnât say anything to this.
âBut you donât want to do things like that, and I⌠think that doing things that way would be relying far too much on you.â Natsuya chuckled lightly. âAkatsuki Mitarai is my opponent as you said. You canât retract those words of yours.â
Seiji simply looked at her.
âYouâve already worked so hard that youâve successfully become a Yin-Yang Master. If I still want to retreat after all that, it would be so unseemly. Thatâs why, for the sake of your willfulness and my prideâŚâ
There was a sharp glint in the Yoruhana Family daughterâs eyes.
âLetâs get rid of that guy together!â
Seiji smiled as he heard her words filled with battle spirit.
What was the correct strategy for two weaker Yin-Yang Masters allied together to deal with a much stronger Yin-Yang Master?
The first and most basic strategy that anyone would be able to think of would be to use an advantage of numbers in Spirit-branded Retainers. Use swarm tactics to take care of the enemyâs Spirit-branded Retainers, then finally surround and defeat Akatsuki. Or, at the very start, use swarm tactics to overwhelm him.
However, Natsuya eliminated this option immediately. It wasnât because it was too shallow, but rather because they wouldnât be able to carry it out.
âTo my knowledge, Akatsuki Mitarai has three Spirit-branded Retainers. If thereâs no limitations set on the duel, then he has the capability to hire another two temporary Spirit-branded Retainers for a total of five,â Natsuya explained. âAs for our side, if I cancel my temporary contract with you, I can have one additional temporary Spirit-branded Retainer. As for you⌠even if youâre capable of maintaining two Spirit-branded Retainers with your current level of Spiritual Power, if you add two to Hitaka, Rana, and a temporary hired Spirit-branded Retainer, weâll still only be two Yin-Yang Masters and five Spirit-branded Retainers, an advantage of only one person over Akatsuki. Thatâs not much to speak of.â
âAlso, since I donât possess a Soul Spirit yet, Iâm currently still your temporary Spirit-branded Retainer; if you cancel the temporary contract and I lose my bonded spirit, my combat strength will be greatly decreased,â Seiji added.
âIndeed. So, assuming that the duel wonât have any number restrictions for the participants, it still wouldnât be an advantage for us. And only restricting the number that he can have on his side without restricting our side⌠thatâs pretty much impossible to negotiate for as a condition.â
Since they were unable to have the advantage in quantity, they would have to turn to quality instead.
âWe should form a âSpirit-branded Alliance,'â Natsuya suggested.
âWhatâs that?â
âThatâs a process by which two Yin-Yang Masters summon spirits for each other, making both Yin-Yang Masters into each otherâs Spirit-branded Retainer. This will form an intimate alliance, and itâs also slightly stronger than typical Spirit-branded Retainer contracts.â Natsuya paused for a moment. âThat is to say, Iâm going to modify the type of contract you have with me, and you need to summon a spirit for me and make me into your Spirit-branded Retainer.â
There was this type of trick available? Seiji raised his eyebrows in surprise.
âAfter forming a âSpirit-branded Allianceâ with each other, both of us will become a bit stronger, but itâll also put more of a burden on us. Since I have a Soul Spirit already, adding a bonded spirit to myself as well will increase the burden upon me even further, although Iâll also become stronger.â
âSo, itâs just like equipping yourself with a second weapon thatâs a bit heavy. While your attack power will increase, there will be a greater burden to carry?â
âYes, thatâs an apt analogy.â Natsuya nodded. âAs for the problem of the burden, I wonât be able to maintain this Spirit-branded Alliance indefinitely. However, maintaining it until the conclusion of the duel should be fine. Also, since the Spirit-branded Alliance is two-way, itâs a more intimate connection compared to normal Spirit-branded Retainer contracts. The effect of âMana Exchangeâ will occur.â
âWhatâs that?â
âSimply speaking, after spiritually connecting to each other, your Mana and mine will be connected as well. It might help to improve both our powers, but also might cause the opposite effect and decrease our powers if we lack compatibility.â
âThen what should we do to make sure that our powers are increased rather than decreased?â
âThat depends on the compatibility. I donât know the specifics, either. We can only find out by trying.â
âWeâll be able to become much stronger if weâre highly compatible. If not, weâll actually become weakerâŚâ Seiji blinked at this. âThis sounds rather similar to some situation from a hot-blooded battle manga.â
âHah, I totally agree.â Natsuya smiled.
âI believe that we should be highly compatible. Let us become powerful partners⌠no, the strongest combination of all!â Seiji made an immature pose that he copied from a battle mangaâs main character as he spoke in a passionate tone.
When the president heard him say âwe should be highly compatible,â her heartbeat rapidly increased and her face began to slightly flush red.
âPartners⌠that sounds really nice.â More ripples appeared in her heart when she tried imagining this.
âNo, no, I canât be thinking of such things right now.â
Natsuya forced herself to regain her senses as she continued explaining, âAlso, after making the Spirit-branded Alliance with me, if you still have extra Spiritual Power remaining, go ahead and make Rana into your Spirit-branded Retainer as well.â
There was this type of trick as well!? Seiji was incredibly astonished.
âKirin-san is your Spirit-branded Retainer already. Itâs possible for me to contract with her as well?â
âYes, as long as I, the original contractor, agree to it.â Natsuya nodded. âThis is known as a âDouble Spirit Contract.â Similar to how Iâll have to undertake the burden of both a Soul Spirit and a bonded spirit, Rana will undertake an additional burden as well, and also receive a suitable increase in her power level.â
âCan she undertake such a burden?â
âItâs not a problem. Ranaâs probably more capable of maintaining this burden for longer than even I am. No need to worry.â
âAlright, then⌠and if I still have extra Spiritual Power, should I do the same thing for Shuho-san?â
âYes, if youâre still capable of it.â
Having Natsuya and her two Spirit-branded Retainers all become his own Spirit-branded Retainers as well⌠Seiji felt that this was all quite subtle.
More accurately speaking, he was acting the part of something similar to being an additional equipment storage warehouse for them, rather than truly becoming their master and them becoming his servants.
But even if it was only in name, having three beautiful girls join him as his Spirit-branded Retainers sounded really nice to him.
He tried imagining Natsuya, Hitaka, and Rana, the tree beauties calling himself âMasterâ all together⌠Yep, he gave this scene one hundred and thirty-two likes!
Hey wait, wasnât this scene similar to what he saw when he was undergoing [Visualization]?
