Mitsuya is a young man with downturned lavender eyes, short silver-lilac hair, and a muscular body. He has a concealed dragon tattoo identical to Ken Ryuguji's on his right temple and a black huggie earring in a cross design on his left ear. When not on gang duty, he wears a variety of casual outfits or the mandatory school uniform. He cares for his two younger sisters, Luna and Mana, acting as both their mother and father since their mother is rarely at home due to work. Mitsuya is a calm.
