"Ah, now I can go back! Master, thank you very much!"
"Feel free to visit anytime. I'll even give you some training. Ah, take this sword and letter with you. Show the letter to the current king, and he'll understand."
Kain took the sword and the letter. When he drew the sword from its sheath, it was a single-edged blade, slightly curved like a katana. After confirming the blade, which shimmered in seven colors, he sheathed it and put it away in his item box.
"This is the sword I used in the past. I made it to resemble a katana. I hope you use this weapon well."
"I gratefully accept it. I'll come visit again, 'Transfer.'"
Kain had trained for several years in the world Yuuya created.
In that world, one year was equivalent to one day in this world.
Although Kain should have grown physically over the years, he appeared unchanged from a few days ago as he transferred near the mansion.
It might have been just a few days in this world, but Kain had completed five years of training and returned.
Looking at his mansion from the outside, he finally felt that he had come home.
He gently opened the door to his mansion and entered the lobby.
"I'm back..."
Kain whispered softly.
In the lobby, Coran and Sylvia were talking in a circle with several knights.
Thinking something must have happened, Kain approached the circle.
"Really, did you search the entire capital and its surroundings! He must be somewhere. Please search for him."
Sylvia was giving instructions to the knights with intense determination.
Kain decided to ask one of the knights standing behind the circle.
"Sir Knight, what happened?"
"Baron Kain has gone missing. He said he would return in two days, but it's already been five days since he left. Therefore, a search party has been formed, including the capital and its surroundings."
The knight answered.
"..."
Cold sweat dripped down Kain's forehead...
"By the way, who are you? This is Baron Kain's mansion. Are you here to help search for Baron Kain as an adventurer? If so, you should ask Lord Coran, the steward."
The knight explained politely. Hearing his voice, Coran and Sylvia turned to look.
Their gazes caught Kain.
Then, Sylvia dropped the documents she was holding.
She trembled and began to cry.
"Gain, you jerk!!!"
Sylvia rushed over.
She pressed her head against Kain's chest and cried.
The knight who had been talking was also surprised, not realizing it was Baron Kain himself.
"I'm so glad. You said you'd be back in two days, but you didn't return for five days."
While stroking Sylvia's head, Kain apologized to everyone.
"Everyone, I'm sorry for the trouble. I've returned safely, so please rest assured."
Kain bowed to the knights who had searched for him.
"Baron Kain, please raise your head. There were concerns at the castle as well. I will immediately report to the castle."
The knights bowed and left.
After moving to a private room, Kain, Coran, and Sylvia were left alone.
"Baron Kain, please explain properly."
Kain was hesitant to explain. He couldn't say he had been with the first king.
"I went to the monster forest in the Gracia territory, and I got lost there..."
The two gave him a cold stare.
"It doesn't work."
"I'm sorry. I can't explain that now. If I do, it will be to the king or the prime minister."
Kain said honestly. The word "king" made the two of them swallow hard.
"Also, I have a request. I want to keep summoned creatures at home."
"Wh-what?"
"I think you'll understand when you see them..."
'Summon "Haku" "Gin"'
A magic circle appeared on the ground, and a white wolf and a silver dragon, both about the size of a large dog, appeared.
"Wh-what!!!"
Coran and Sylvia were surprised by the sudden appearance of the white wolf and silver dragon, but Sylvia reached out her hand, captivated by their cuteness.
"Cute..."
Sylvia slowly extended her hand toward the white wolf, Haku.
Haku hid behind Kain. Of course, Gin did the same.
"Oh..."
Sylvia looked sad and withdrew her hand.
"I plan to raise these two at home."
"Baron Kain, what kind of creatures are these two?"
"Please don't ask... Haku, Gin, listen to Sylvia, okay?"
"Woof" "Kyui"
Both responded.
"Haku and Gin are very smart and understand words."
"Understood, Baron Kain."
Both seemed to agree.
"Oh, by the way, Baron Kain."
"Hmm? What is it?"
Coran spoke as if remembering something.
"Princess Teresia and Sir Silk were very worried... They've even skipped school. They've been visiting every day after school."
"Oh..."
Kain felt a cold sensation on his back.
"I think you'll receive a summons from the castle. Please take care of it."
"Coran, can't I just say I was visiting my hometown or something..."
"Unfortunately, no... The knights who searched for you were arranged by Princess Teresia, so it's impossible."
Kain braced himself for the scolding that was to come.
◇◇◇
The next day, as soon as Kain arrived at school, he was caught by Teres and Silk.
"Yesterday, I heard from the search party's knight. Baron Kain, where did you go? We were really worried."
"Kain, where did you go while skipping school? Sit down in seiza first."
He was attacked by both. Teres explained how worried she had been and even started crying halfway through.
Kain explained that he had gotten lost in the monster forest and was taken in by a person living there.
"I've never seen the monster forest, but it's full of strong monsters, right? It's surprising that someone lives there..."
After the explanation, both were very interested in the monster forest. It was Teres' ancestor, but he couldn't say that.
"The red dragon we have at home was also found in the monster forest. The person was very strong and gave me some training, so I ended up staying there."
"My father wasn't worried, but he said to come to the castle immediately when you returned. He also said, 'What is he planning to do next...'"
"...I'll go to the castle after school..."
Kain's shoulders drooped, and he felt gloomy throughout the day.
"I want to go home now..."
Of course, he couldn't just go home. Teres and Silk were on either side of him.
"Let's go to my father's place."
They got into the carriage that had come to pick up Teres and headed to the castle.
They were led to the usual reception room and served tea. Kain waited for the king, suppressing his desire to go home.
After a while, the king and the prime minister entered.
"Ah, Kain, you're safe. I wasn't worried, but Teres was very anxious. Where did you go?"
"Well, I was meeting someone on Xenom's request."
The mention of the creator god's name surprised both of them.
Kain took the letter out of his item box and handed it to the king.
"This person asked me to give this letter to Your Majesty..."
The king stiffened when he saw the seal on the letter.
"Kain, this is the seal of the Esfort royal family. Who pressed this seal..."
He broke the seal and started reading.
As he read, the king's expression changed...
After finishing, he passed the letter to the prime minister, who also read it and his expression changed.
"Y-You can't be serious... Kain, you were with the First King... and he has become a god..."
"...Yes, that's right. The First King created another world and became the creator god of that world."
Kain nodded in agreement.
He then placed the sword he received with the letter on the table.
"This is... the katana that the First King is said to have used."
"Yes, I received it from the First King."
Saying that, he put the sword back in his item box.
"The First King wrote that you have a mission. Can you tell us about it?"
The king asked. Kain shook his head.
"Your Majesty, I'm sorry, but I can't talk about that mission now. The time isn't right, and it's not confirmed yet."
Their gazes met, and the king exhaled.
"The First King wrote that he trained you. How was it?"
"Of course, it was very tough. I was trained day and night for five years."
Kain spoke honestly without thinking.
"You... Did you say five years?"
"Ah!!!"
"Let's hear more about it..."
As usual, Kain, who was a bit absent-minded, and the king, who wore a suspicious smile.
