First step

Tamazuki knew that he should agree, especially when he knew Tohsaka Rin was a future heroine...

<As your disciple, you can mold her in the way you wish. Then when she reaches a suitable age, then you...>

Tamazuki decided to ignore the system since he didn't plan to do anything to Rin. He patted her head and said, "Maybe, if you are a little older right now, you are too young. If you learn too early, you might damage your growth."

"Ehhh...."

Rin was disappointed.

"Rin, you can't be selfish, okay?" Aoi quickly stopped her daughter since she knew that Tamazuki rejected Rin softly. Nevertheless, wasn't it normal? She knew that he had faced many things, and for now, he wasn't ready to open his heart to anyone. Maybe a few years later, but for now, he needs time.

Still, if Rin could become his student, Aoi didn't really mind since, unlike a "Mage," she could tell that this martial art was for those with a sincere heart and kindness.

If Tamazuki knew what Aoi was thinking, he wouldn't deny her since she was correct. While he knew that he was a bastard, he knew that Bang created this "Water Stream Rock Smashing Fist" due to his will, who wanted to walk on the path of kindness once again.

"Though, I can teach you a breathing method and also a physical training routine for a basic before you learn the real thing."

"Eh? Really? Is that okay?"

"Yes, but this isn't easy, and it might be boring, you know?"

"I don't mind!"

While Rin was from a "Mage" family, she didn't mind walking on the path of martial arts.

Fighting the bad and protecting the weak!

She wished to become such a martial artist!

Her eyes shone as she thought of such a future.

"Tamazuki-kun, is that really okay?" Aoi looked at her daughter helplessly and looked at Tamazuki with an apologetic expression.

"It's something that can be learned by anyone, and it isn't like it is a secret, Tohsaka-san."

While Tamazuki realized Aoi had called him for the first time, he still used to call her by her family name.

"Sensei, you should call Mom by her name instead of her family name!" Rin quickly said.

Tamazuki's lips twitched, wondering whether this daughter of Aoi wished him to take down her mother. "But I am not your Sensei yet, Rin-chan."

Rin stuck out her tongue and knew that it was only a time before she would become his disciple, so she wanted him to have a good relationship with her mother.

"Yes, I don't mind if you call me that." Aoi smiled and agreed to her daughter's request.

"...."

Tamazuki thought that [Jupiter] was really a bug-like skill, yet when he thought that it was an Ultimate Skill, he felt that it was quite normal.

By using this skill, he could amplify the good feeling of someone without them noticing it.

It was also the reason why he was easily likable by anyone.

Yet, it also wasn't so omnipotent that he could be easily liked by Aoi's husband since his presence would definitely bring harm to their marriage.

Though, why did he feel excited for some reason?

He could imagine how Aoi would feel guilty as she drowned in pleasure by him.

He shuddered and quickly shook his head.

Was it the effect of devouring that being?

Had he become evil because of that being?

Probably not.

After all, he was a villain, so wasn't it normal for him to do a bad thing?

Still, this was too early.

He couldn't show his fangs yet. He needed to appear weak, making his prey lower their guards until they showed their everything to him and even presented him with their beautiful and plump bodies into him without hesitation.

"It's already night. How about you sleep first?"

"Eh? But what about my first lesson, Sensei?" Rin pouted.

He showed helplessness. "How about tomorrow?"

"Tomorrow? Really?"

"Yes."

"Will you promise me?"

"I promise."

"If you break a promise, what will you do, Sensei?" Rin asked.

Tamazuki thought that this little girl was so crafty. "Rin, I will tell you a secret."

"What?" Rin looked at her teacher curiously.

"A smart girl isn't popular."

"....." Rin.

Aoi couldn't help but chuckle hearing Tamazuki's words.

"Mom! Why are you laughing?! Sensei, what do you mean by that?!" Rin looked angrily at her mother before she looked at Tamazuki begrudgingly. Still, who cares about the boys? The boys in her class were so stupid, and she didn't care about them!

"You are still young, Rin. Maybe, when you are in your 20s that you will understand this sentence."

"That's too long!"

"Not really. It will pass without you even realizing it."

Rin looked at Tamazuki with an unconvinced expression, yet it was normal since she was still young, and she felt that such a time was a long time.

However, Aoi understood that when one became an adult, everything moved even faster, especially in the 21st century when technology had become so advanced.

Though the timeline in this world was still in the 20th century.

Nevertheless, those words made Tamazuki appear deeper in their eyes.

Yet, this was normal.

For him, this world was easy.

In this world, nothing could harm him, especially after his experience of being chased by that being.

Was there a stronger being than God in the world where he was before in this world?

He wasn't sure, but for now, he was okay, and because of that, he didn't want to endanger the two of them.

They talked for a while before it was time to sleep.

Rin was an elementary school student and a little girl, so she needed to sleep early. Even if she didn't want to, her mother wouldn't allow her to sleep late.

Gaining their trust, Aoi also prepared a room for him in the guest room to sleep. However, he didn't intend to stay since the war was about to start, and he could tell that he wasn't chosen, especially when he didn't find the sign that he was chosen on his left hand.

Even so, it didn't mean that he had fallen into despair.

Instead, he had an idea of how to get a qualification to enter this war, but before that, he had to leave this house first. After all, if he stayed in this house, many things would be quite hard to achieve. Moreover, the husband of Aoi and the father of Rin were his competitors.

Though, toward this person, he didn't need to do anything since someone would deal with that person.

Still, when he was about to leave, someone stood at the entrance of his room.

"?!"

The two were startled.

"Aoi-san?"

"Tamazuki-kun? Are you going to leave?"

Aoi stood there in her green colored dress and shawl to give her warmth on this night.

"Yes."

Tamazuki nodded and didn't hide his intention.

"I see..."

The sound of disappointment in her voice couldn't be hidden, but she knew that she couldn't stop him.

Still, once again, it might be an impulse, especially when many things happen in her life, so she said, "But before you leave, can you accompany me to drink for a while?"
