Senpai is a young, light-skinned man with a constant blush, strawberry blonde hair, and wide blue eyes. He wears a partially tucked-in periwinkle blue button-up shirt, a loose pink tie, grayish-purple jeans held up by a black belt with a silver buckle, and grayish-purple shoes. He carries a brown backpack in his right hand over his right shoulder. His head sparkles whenever he is not singing.
