Tatsuyuki is an exceptionally tall, well-built man, possessing defined muscles and wide shoulders. He has small black eyes, a circular nose, and a prominently large, square jaw, with the lower jaw protruding outwards, and his mouth is notably high up on his face as a result. Tatsuyuki has an affable and chipper personality. He gives a hug to Shoto Todoroki and Katsuki Bakugo while praising them for beating their first villains, before offering to clean up the mess of the fight.
