Kotoko has ankle-length light pink hair with short straight bangs and slightly curved in locks on the side of her head tied into high pigtails and a shade of vivid pink colored eyes with speech bubbles acting as designs for the irises. She wears a hot pink hairband with two horns atop, both bent in and the left one having a white bow with pink polka-dots by its base. It also is branded with the emblem of the "Fighter" class in between the horns.
