×Tomioka×

On the first day of classes at Kimetsu Gakuen (back to school, end of vacation), Inosuke, a student who doesn't like to follow the rules, wears his uniform open, only wearing his jacket, pants, and even shoes. He threatens Zenitsu, who is responsible for checking uniforms, to make sure no one enters without a uniform. But this doesn't work on Inosuke. The first class consists of two physical education periods taught by Professor Tomioka Giyu, the strict physical education teacher who keeps the rules in line. This is why most of the time the students dislike him. In classroom 4 of the first year of high school, the students were chatting, playing some games, standing or scattered around the room, while Inosuke was different; he was throwing paper balls at the girls. But suddenly, Professor Tomioka entered the room to start the class and go to the large gym. But when Tomioka was at the door, he accidentally received five hits to the face from Inosuke because he was throwing it at the girls. Then the students stopped what they were doing, fell silent, and sat down in the chairs at each table they were at.
