Ultimate Being from the Tokonosu City

Kagaya is a madman.

As Isao entered the train, starting his journey to Tokyo, he couldn't help but think so. Yet, when one was born in the Ubuyashiki house, it was impossible for one to be sane, especially when he knew that Kagaya's father died by committing suicide. Moreover, everyone who was born in that house would die early. Even worse, they also had a duty to be the leader of the Demon Slayer Corps, ordering everyone to fight the demon and then watching them die.

Kagaya's father committed suicide because he was unable to handle the pressure of watching the Demon Slayers die one by one when they fought a demon. 

Lastly, when Isao thought about how Kagaya would detonate a bomb to kill Muzan, committing a suicide bombing while also letting his wife and his two girls follow him, dying, he knew that Kagaya wasn't right in the head. 

Yet, unlike him, who could live almost unlimitedly due to Doma's DNA, Kagaya could only live about 20s years or so. 

If Kagaya wasn't in a hurry, then could he only wait for death? 

Every second of his life was important, and if Kagaya saw those modern kids who procrastinated their actions, Isao was sure that Kagaya would get angry to death. 

However, Kagaya had nothing to do with him. 

Isao wasn't part of the Demon Slayer Corps anyway, and Kagaya wasn't the only madman in this world, so why should he care? 

Instead of that, he wondered what kind of business he should open in Tokyo. 

Frankly, Isao had no idea. Well, he had a lot of ideas, but he wasn't sure which he should do first. At the same time, he was thinking of going back to the world of the "High School of the Dead" to make his decision and take the DNA of university professors so he could gain knowledge that would help him in this world. 

Sciences, Engineering, Medicine, Agriculture, Economics, Law, and Pharmaceuticals. 

Isao decided to go back and get all of that knowledge first. 

However, before that, he wanted to see the difference between the big city in the current era and the future era. While he had been in this world, he had only been in the countryside, and it was impossible for him to go back before he saw Tokyo in the Taisho period. 

While it was strange, Isao felt like a tourist who had gone to the Maldives or Hawaii for a trip, taking a moment of rest from their bustling daily lives. 

Yet the comfort that came from this trip was far from being described as comforting. 

A mix of various smells from the people and burnt coal, hard wooden benches that were hardly comfortable, blaring noise from the train, and the trails of black smoke that tainted this beautiful scenery. 

Isao suddenly missed the five-star hotel trip he took with his women in the past. 

Yet, whether in this world or the world of the "High School of the Dead," it was impossible for him to take such a trip anymore. 

Fortunately, his life was quite hard, so even if this place was quite uncomfortable, he could bear it. 

If it was a comfort, it was the fact that he had a beautiful woman by his side. 

Amane Ubuyashiki. 

The wife of Kagaya and the mother of his children. 

This year, she was 25, an age when many women were still single in modern times, but during the Taisho period, she bore many children. 

Yet, even so, her body was still taut, and pregnancy didn't diminish her beauty. 

Sitting quietly by his side, Amane always straightened her back and put her hands on the top of her thighs without saying a word.

While partly due to her being a silent type, another reason was that she didn't want to annoy Isao. 

Isao also knew this, and he didn't intend to be gentle with Amane, as he wished for her to leave him. 

Yes, Amane might be beautiful, but she is Kagaya's wife; what is he going to do with her?

If it had been in the past, Isao might have taken the initiative to make a move toward such a beautiful young wife, but as he had decided to become a good guy, such an act was definitely impossible for him to do. 

Yet, even if he was such a good guy, it was impossible for him to be manipulated. 

If he said something, he would lose, so he just decided to wait for Amane to take the initiative to talk with him. 

Amane also thought the same and waited for Isao to take the initiative to talk with her. Even though Isao rejected the invitation to enter the Demon Slayer Corps, it was impossible for her husband to give up, and he told her to do everything she had to do to invite him.

So, even if Isao mocked, spat, or even beat her, Amane wouldn't give up and kept coming to him, inviting him. 

Yet, he ignored her, so it put her at a loss. 

She thought that Isao would talk with her, even if his tone was spitful; it didn't matter since being hated was much better than being ignored. 

At the same time, she also knew that Isao didn't have a good impression of them. 

Whether it was Kagaya, her, or the Demon Slayer Corps, they knew nothing about Isao. 

Isao also only told them his name yesterday, and it was impossible to get his information within just a day.

Moreover, was his name a real name? 

As for Kanae? 

With Isao's attitude, they believed that Isao just played around. 

Even Amane thought so, especially considering how obscene Isao was last night. 

So, somehow, a question emerged in her head, "What if I let him sleep with me?" After all, she had to do everything to invite him to the Demon Slayer Corps, yet even if she was the wife of Kagaya, it didn't mean she was omnipotent, and there was something that she could do and couldn't do. 

The only solution she could think of to make him join the Demon Slayer Corps was to seduce him, letting him enjoy her moist and taut body.

When such a thought crossed her mind, the thought of him pounding his large cock onto Kanae's pussy emerged in her mind, but instead of Kanae, she was the one who pounded by him, becoming an animal that had lost her reason due to pleasure. 

Twist!

Amane twisted the skin of her hand, feeling a sharp pain that woke her up from her dirty thoughts. 

How could you think such a thing?

She was a wife and also a mother. 

How could she have such despicable thoughts? 

As she admonished herself inside her mind, his voice woke her up. 

"What's wrong?" 

"I am okay. There is nothing to worry about."

Amane didn't expect that Isao would suddenly ask her when she had just thought of herself being held by him, and it threw her off. This should have been a chance to talk since he had broken the silence, yet due to how filthy her thoughts were, she lost her chance to take the initiative to talk about the Demon Slayer Corps. The words that came out of her mouth became strangely suspicious since she was afraid that her dirty thoughts would be found out. 

Hearing her answer, Isao only looked at Amane strangely, yet he couldn't look away when he saw the noticeable pinkness of her cheeks that spread toward her white nape. 

Amane also noticed his gaze and didn't let go of this chance to stare into his eyes, ready to take the initiative to talk about the Demon Slayer Corps. Yet, watching his eyes, which were full of desire toward her, she lost her calm once again, but she couldn't look away. Instead, her eyes turned moist and charming, and her body became hot at the thought of the possibility that might happen between the two. 

Yet, even if something might happen between the two, with their status, how could they express those taboo thoughts straightforwardly in public? 

Fortunately, Isao looked away, erasing the ambiguous atmosphere between them. 

Amane breathed in relief as she held her chest, afraid something might really become what she thought to be. 

"Look, we're about to arrive." 

"Hmm?" 

Yet, when Amane saw Isao smiling as he reminded her that they were about to arrive in Tokyo, she was in a daze and strangely anticipating the thought of being with him in the most prosperous city in this country.

I apologize. 

Even though I have made a list, I think that the third world is going to be "Baki."

Thanks to those who have recommended it to me.

Still, it might take a while, so enjoy the "Kimetsu no Yaiba" first.

Thanks~!
