Always messing things up: you could call it Tokumaru's specialty. He's got no manners at all, but he doesn't seem to notice himself. His sister demands he has to follow Tea Ceremony lessons at the club at their school, in order to improve himself. There, he meets Hasune. Being the president of the Tea Ceremony club, Hasune starts mentoring Tokumaru. Though, it's only a matter of time before he's doing more to Tokumaru.
