Eye color:Dark purple
appearance:
His eyebrows were constantly furrowed, which made him look constantly angry. His hair was cut short, and only a small tuft of unruly black hair remained on top of his head. He also had a large jagged scar that ran from his ear across his right cheekbone to his nose.
Later, when he was seen again in the Butterfly Mansion, the Genius who had reached puberty looked much more wild. He grew dramatically, and his height was almost 180 centimeters, and he also had slanted large almond-shaped eyes with purple irises, like Sanemi's. His hair has become much longer and is gathered in a mohawk, the strands have become much longer and hang down his neck. It is also noted that his boyish features have softened, he has become more muscular and has received many scars all over his body. His clothes had changed to a dark olive green version of the Demon Slayer uniform, over which he still wore his old purple yukata.

Initially, Genia was a foul-mouthed and short-tempered man, a "lone wolf" who refused any help and showed no interest in politeness or good manners. During the final selection, he rudely treated Kanata Ubayashiki, grabbing her by the hair and yelling at her because of his impatience, and later provoked Tanjiro Kamado to a direct confrontation with him using physical force in an attempt to defuse the situation. His quick temper and cocky tone are very similar to the way his older brother Sanemi speaks.
He became more open to cooperation during the battle with Hantengu, the Fourth Highest Rank, where he worked alongside Tanjiro, Mitsuri Kanroji, and Nezuko Kamado. Over time, he learned to be more sociable and less rude towards others, especially Tanjiro and his friends.
