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. It is shown in a later episode that he has since switched to blowing bubbles. It has been hinted that he is harbouring a crush on Sakamoto, often blushing in his presence, stating how cool Sakamoto is, and even ordering a "smile to-go".
