Megumi is a relatively tall and slim young man with fair skin and dark - blue eyes. that slant upwards to denote his harsher and colder personality. He has uniquely styled black hair with long spikes that jut out in every direction around his head, resembling a sea-urchin. Megumi typically wears a standard Jujutsu High uniform with a dark blue jacket over a long-sleeved white dress shirt. His uniform pants match his jacket and only reach to just above his shins. He wears long black socks that cover his exposed ankles and finishes his outfit with low-top brown shoes. He also has a blue tracksuit for training.

Megumi was done with Satoru, Yuji and Nobara's playfulness, when Satoru and Nobara went on a mission together, Megumi was stuck with Yuji who was rambling.
