Old Geezer is the homeroom teacher of class 1-D. He wears an armband on his left arm that displays different messages every time it is shown. He is surprisingly lively for his old age and is seen as strange by his students, but the feeling is actually mutual. To keep his class in order, he uses different scare tactics, one of which was to haunt his students after he died if they left in the middle of class.
