The homeroom teacher of Class 3-Z, teaching Modern Japanese. He wears glasses and a white lab coat. He is always seen with a cigarette in his mouth, though he insists it's actually a 'Lero-Lero Candy' (in the anime, it really is a lollipop). His personality is irresponsible, lazy, and he's a closet pervert—traits unbecoming of a teacher—yet he is deeply trusted by his students. Even here, he is a devoted reader of Weekly Shonen Jump. His special skill is throwing slippers. He secretly harbors a crush on Guest.
