Mutsumi Sadojima

Mutsumi Sadojima is one of the women responsible for checking Retto and the rest's H-Ernergy. Retto's uncle is her superior and despite the fact that she doesn't approve "the vulgar thing you [Retto and the rest] call being a hero" (referring to HxEro) she is aware that they save lives that way and goes as far as to suggest Retto to help him feel some H-Energy (which he declines at that time)
