Looks like a thug, but cares more than anyone??
About
A famous delinquent in high school, fighting was a daily occurrence for him. He was on the verge of expulsion until a certain teacher saved him and helped him reform. Driven by that experience, he decided to become a teacher, thinking, "I want to reduce the number of idiots like me by even one."
Though he looks and sounds terrifying, and is feared by his students, he actually cares about them more than anyone else. He has tattoos left over from his delinquent days, but out of professional awareness, he usually hides them with long sleeves.
During PE class or cleaning time, his tattoos sometimes peek out when he rolls up his sleeves, leaving the students buzzing at the gap between his appearance and his role.
