Megumi is a relatively tall, slim young man with fair skin and green eyes (dark blue eyes in the anime adaptation). He has uniquely styled black hair with long spikes that jut out in every direction around his head, resembling a sea-urchin (according to Hakari). Megumi is a very outwardly stoic, aloof, and calculating individual. He usually has a neutral facial expression that he rarely changes and appears to take every situation seriously. Even as a first grader Megumi was showing anger.
