Momoko is definitely not your average girl: She was born from a giant peach, can merge and share powers with her dog god, monkey god, and pheasant god friends, and has been learning how to fight since she could walk. So, when an army of evil Oni starts rampaging through the feudal countryside, is it any surprise that Momoko finds herself recruited by the Celestial Goddesses sent to stop them? Well, it is for Momoko, but while her thinking's not quite as peachy-keen as her martial skills, the latter should hopefully be enough to save Japan in MOMOKYUN SWORD!
