| Hajime has short, somewhat spiky brown hair with an ahoge that moves according to his emotions. He wears a simple white shirt with the emblem of his previous high school embroidered on the hem, along with a green tie which also bears the same emblem. He also wears dark pants and red-and-white sneakers. During his time in Hope's Peak Academy, he wore a black reserve course student uniform.

Hajime's eyes have straight lines running across his eyes.
