It's that time of the month, and you know what that means...a visit from Aunt Flo—scratch that—Little Miss P! This pink, anthropomorphized period's not so lean, kinda mean, and a gut-punching, butt- kicking machine! (Just ask Mr. Erection...) Follow Little Miss P as she traverses time advising, harassing, abusing, and comforting women on her (usually) monthly visits in this uniquely weird and surprisingly touching manga!
