Megumi is a relatively tall, slim young man with fair skin and green eyes (dark blue 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, making it appear as if he takes every situation seriously.
