Kei Uomi

魚臣慧

A gaming companion Sanraku met through a "kusoge" (crappy game), and one of Japan's top-tier professional fighting game players, currently affiliated with a pro gaming team under the handle Kei. While she appears as an adorable female character in Shangri-La Frontier, Kei is, in reality, male.

Thanks to his encounter with Sanraku, he has been dragged deep into the kusoge swamp. He boasts exceptional skill in player-versus-player combat.
