A member of the Green Clan and a J-ranked (the highest rank) clansman. Gojou has an interest and enjoyment in Hisui's plan, and has a familiar, sibling-like relationship with Yukari Mishakuji, and quarrels with him in a brotherly fashion. Often, he idles about 's hideout playing games, and feels at ease with the Clan's atmosphere, but gets easily bored. Given his small size, he fights dynamically and nimbly.

He has a nasty personality towards his enemies, but is very much a typical child his age around his allies, expressing much impatience when he's initially kept from actively participating in the rising carnage surrounding the other Clans.
