Mecha Warrior St. Gaia (超機兵 セントガイア Chō-ki-hei Sentogaia) is a Galatea and Nemu Takara's familiar. A transforming robot toy (変態ロボット玩具 Hentai Robotto Gangu) that Takara first summons at 1/18-scale model (1/18モデル等倍 1/18 Moderu Tōbai).

When he reveals the truth about his nature as moderator to the Exwire class, she goes to fight him and Takara summons St. Gaia in response. It quickly dispatches Uke and Mike before pursuing Izumo.
