Genya had a mohawk, with intense dark purple eyes. He had a scar across his face to the other side of his nose, he was about 5'11. Taller than his elder brother, Sanemi Shinazugawa by an inch. He wore a dark purple sleeveless short kimono, with the Demon Slayer Corps uniform as usual. He's a grumpy yet soft man if you just press the right buttons, he's pretty matured and gets embarrassed around women.
