it was a lie

"Rule 3 - you have told me that no one way of breathing has any effect on you unlike any other demon. So I am not going to restrict which breathing style you learn, but you should learn at least one breathing technique. And if you can't learn it, you have to discover why.

Rule 4: Even if you are not a merciful person, when you see someone who needs help, you should help them like a merciful person.

Rule 5 - "You must exorcise the same number of demons as a demon slayer wearing a kanoto must exorcise in one year."

"As long as you follow the rules I've told you, you can live as free as any other demon slayer. This man you see here is a retired Hashira who has agreed to share his home with you until you adapt to this life. He will also teach you the basic rules of swordsmanship and water breathing."

Kagaya guessed that the look of surprise on Yuto's face was because of the blood he had given him, and so when he said the rules, he also said in a veiled way why he had given him the blood. But he was wrong in his guess, Yuto's surprised expression was caused by the old man standing next to them.

When Yuto heard that man's name, he realized that he was the main character's first master. But there was one problem, he thought that in the current timeline, the man should be much younger.

After thinking about it for a while, Yuto decided that he couldn't remember enough about the Demon Slayers anime and stopped thinking about it. As a result, he decided to focus on the life in front of him.

------- 

Yuto looked down at the few folded dresses that lay at his feet and looked up at himself in the mirror. Black messy, or rather wavy, hair fell over his shoulders, with red eyes that were easily noticeable through the hair. When he looked a little lower in the mirror he saw his slightly muscular and firm upper body and when he tilted his head a little lower he saw his legs and his sexual member between them.

It was almost like the perfect male body structure he had seen in physics books in his previous life. He had muscles all over his body, but the muscles were not easily visible, especially when he did not expose them. His whole body was perfectly symmetrical and the way he stood was almost perfect, even if he didn't especially try.

He knew that he would not have to worry about bloodlessnes any time soon because he had taken enough blood. So he used the blood art to make some changes to his body that would make his own perfection even less perfect. For example, he reduced his height from 1.9 meters to 1.75 meters, which is remarkable among the Japanese. Other than that, he made many small changes that destroyed the symmetry of his body, but it's not worth talking about. The only reason he did such a thing was his absurd belief that perfection was the enemy of beauty.

After putting on the demon slayer clothes he had been given, Yuto tried to strike a cool pose in front of the mirror a few times. But the fact that he didn't have a sword in his hand made it awkward and embarrassing.

Ignoring this, he posed a few more times and then the door to the room dragged open. Almost all the doors in the old Japanese era were dragged open like this door. Of course, they also had normal doors, but they were usually put in the place to enter the house. The house he was in didn't really follow this generalization.

When he turned around to see who it was, the first thing that he saw was a beautiful woman with white hair, about two inches shorter than he was now, and very attractive purple eyes.

"Yuto-san, if you're ready, you should leave now. Sakonji-san said he still has things to do and can't wait until nightfall to leave."

Yuto opened his mouth to protest, but before he could say anything, Amane harshly threw the scrap of food she was holding in her hand in his face and left the room.

Yuto decided to save his protests for someone else, thinking that she might have woken up on the wrong side of him today, and grabbed the food bag as it slid down his face.

The moment the food bag dropped into his hand, Yuto felt his hands getting wet. It seemed that the throwing action just now had destroyed the food inside this bag, making it useless. Yuto wondered why this woman, who was never angry before, had suddenly gotten so angry, and decided to swallow all of his protests.

Even if the sun was shining outside right now, he could turn himself into a bat, put an umbrella over his head and fly off slowly. Or he could put himself in a huge iron armor and walk around outside that way.

------ a few minutes ago

Sitting on a balcony-like area of the house listening to the birds tweeting in the forest, the woman turned her face to her husband sitting next to her and asked a question.

"What do you think about Yuto?"

"I don't really think much about him. He has a very interesting personality and he's not very dangerous to his environment."

"Not so dangerous? Didn't you say he slaughtered a whole town?"

"Oh, about that. Actually, it was a lie. When the demon slayer who found him saw all the townspeople lying on the ground with cold bodies, he thought they were all dead. According to the report of the demon slayers who later went to that town to collect the bodies, everyone was actually passed out because they were suffering from extreme anemia. When the demon hunters gave some water to the passed out people, most of them woke up. And after a simple meal, almost none of them had any health problems. Of course, two people died, one of them very old and one of them had a fatal congenital disease. Probably if the demon hunter who found him had taken care of the villagers instead of dealing with him, both of them would be alive."
