My Little Monster 13

Mizutani is a self-absorbed overachiever, concerned only with maintaining the highest grades in school. Haru is an impulsive, short-tempered brute, who scares everyone with his explosive bursts of violence. Haru gets suspended on the first day of school when he encounters some bullies harassing a student and dispatches the bullies with some rather bloody violence. Mizutani is tasked with delivering school materials to Haru, who interprets this as an act of friendship and latches on to Mizutani, much to her dismay!
