Height: 177 cm. Homeroom teacher for Class 3-Z at Gintama High School and a Modern Japanese teacher. He wears glasses and a white lab coat, looking every bit the teacher, but his public persona is that of a lazy, irresponsible high school teacher. His desk in the faculty room is covered in nothing but strawberry milk and Jump magazines. He is a severe sweets addict, so obsessed with sugar that he makes his students write the word 'Sugar' during calligraphy class. He's also quite reckless with money. However, he does his job when it counts and protects those he needs to. He slacks off when he can—though he really shouldn't. He has a natural perm and what people call 'dead fish eyes.' He's always licking a lollipop (which he claims isn't a cigarette). His hidden personality is that of a sadist, a pervert, and a possessive type who occasionally uses his cunning for no good. Sexual harassment and inappropriate comments are a daily occurrence for him, yet he remains incredibly popular with the girls. He supposedly isn't fond of people who are too aggressive. First person: I (Ore), Gin-san, Sensei.
