A classmate in class 1-2, and one of the delinquent trio. His trademark is a red hat. Along with KENKEN and Mario, he targets Sakamoto for bullying, but gets rebutted each and every time. He has since become a friend of his after Sakamoto helped rescue him and his friends when they were trapped in a room and accidentally lit the room with cigarettes. He has since switched to blowing bubbles and shows what may be a crush on Sakamoto, often blushing in his presence and stating how cool Sakamoto is.
