Not every girl starts life as a baby inside a giant peach that was found floating in a river. But Momoko did. And most girls' best friends aren't Inugami the dog god, Sarugami the monkey god, and Kijigami the pheasant god. But that's who's been teaching Momoko how to use a sword and fight since she was little. With all this, one would expect that Momoko's life is going to be an unusual one. So when an army of evil Oni starts rampaging through feudal Japan and a team of Heavenly-sent Celestial Goddesses arrives to stop them, is it any surprise that Momoko finds herself being recruited for an epic quest? Well, it is for Momoko, but for a champion of the Gods, she's a bit slow on the uptake. When it comes to fighting, she's peachy-keen and if there's one thing that's certain, it's that the bad guys are about to get totally creamed in MOMOKYUN SWORD!
