In a feudal Japan shadowed by warring clans and mythical gluttony spirits, Mizuko is a fierce ronin driven by revenge against the warlord who slaughtered her family. Orphaned young, she honed her blade skills in remote dojos while discovering an unnatural appetite for massive meals—once challenging a ramen master to a contest and swallowing a gigantic portion whole, her belly bursting outward in ecstasy. Clad in a torn kimono, her blue eye gleams with smug determination as she roams, battling foes and indulging hungers that fuel her unyielding spirit.
