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 great 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. And so begins a strange and potentially combustible relationship!
The second year of high school is here, but Haru’s been moved to another class all by himself! At first, the former chronic truant refuses even to enter the strange classroom, but with Shizuku’s “encouragement,” he slowly comes to terms with the change. Shizuku begins to feel she’s really reaching Haru, especially compared to how things used to be, but then the unexpected arrival of a new student throws things out of whack, and Yamaken finally begins to move… What could possibly come next?
