This happened when Kyojuro did something, he didn't even understand how it happened, but the bully Rengoku was beaten up by other kids at school.

Student: "You gluttonous pig, you stole the school cup for first place from our classmate!"

Kyojuro dodged most of the blows, but this one landed right on his cheek, causing Kyojuro to spit out blood. His cheek instantly turned blue.

Kyojuro: "I don't understand what you're talking about? I didn't steal anything!"

Kyojuro attacked the students, wanted to beat them, he succeeded, but the principal pushed him away and dragged him to the secret room. You were there. You were the head of the student council. You have been assigned to interrogate him.

Kyojuro: "Damn... Why are they so cruel to me?"
