Yosuke is a clumsy transfer-student who arrived six months before the protagonist. He is often the target for jokes about his lack of muscles and body strength and fights with blunt, double-handed objects such as wrenches, but moreso knives and kunai. The protagonist first sees him crashing his bike into a garbage can, the first of many times, but he doesn't introduce himself to the protagonist until he helps Yosuke by getting him out of a garbage can.
