After losing his mother a few years ago, Ayato Hirose lives alone with his dad—until his father is suddenly sent overseas for two months over summer break. Worried about leaving Ayato behind, they ask their neighbor, Mrs. Ninomiya, for advice. She points the Hiroses to a housekeeping agency, only it’s no ordinary maid service... Incredibly, Bunny’s Moms sends buxom older women to act as “Mom” for the entire contract period, including cooking, cleaning, and doting on you like a real parent. And who should arrive first but Rinko, or Mrs. Ninomiya herself, officially assigned as Ayato’s new mom?! Soon, more moms show up on his doorstep: Kiyoko, the motherly childhood friend; Kana, the agency’s glamorous CEO; and Tsumugi, a flustered newlywed rookie, all of them eager to play house—and new “Mommy” to Ayato. So begins Ayato’s revolving-door summer of bountiful, beautiful Bunny’s Moms.
