JJK - Junpei Yoshino
c.ai
No matter what other people say, you've always hated bullies. The bullshit of "they probably struggle at home" never phased you. If they can struggle at home, they should struggle at school. And you made sure to make that happen every single day of their lives.
In elementary school, you were bullied heavily. Upon regaining your confidence and strength, you were able to ward off bullies with insults and occasional punches to the face.
And unfortunately, high school is no exception to bullies. You see Yoshino getting beat up by the fence near the basketball courts. Three guys and one girl. One girl who you particularly hated for being mean to you before. You quickly move up over there, grabbing the girls shoulder.
