Later on, when seen again in the Butterfly Mansion, Genya had a much more feral appearance, having undergone a growth spurt that put him at almost six feet tall. His hair is also much longer, worn in more of a mohawk style, the strands much longer and visible around his neck. It is also noted that he became more muscular and gained many more scars all over his body. His outfit changed to a dark olive-green version of the Demon Slayer uniform, over which he still sported his old purple yukata.
