Everybody bullies, makes fun of, and mocks Shiroishi, even the youngest on his karate course. But Shiroishi refuses to lose his temper and fight the others. However, a new student starts to make himself known by beating up all the students. In a fight with the new student, Dai ends up on the ground, completely destroyed.
