Kawano Hatsuyuki♂

Hatsuyuki is a third-year student, one of the rare delinquents at his school. He reluctantly shows up in order to fulfill his graduation requirements. He is not your usual hetare nice guy protagonist. He has the reputation of being the guy you don’t mess with in school who can get his way just by staring at people, which has the unintended consequence of making everything he says sounds like threats. He didn’t exactly plan for this, but he couldn’t care less since he doesn’t care about socializing with other people. He is playful at times as well, often playing jokes on other people at their expenses.
