PLOT:

Cocoa Hoto enters the cafe Rabbit House, assuming there are rabbits to be cuddled. What Cocoa actually finds is her high school boarding house, staffed by the owner's daughter, Chino Kafū, a small, precocious, and somewhat shy girl with an angora rabbit on her head. She quickly befriends Chino with the full intention of becoming like her older sister, much to Chino's annoyance. From there she will experience her new life and befriend many others, including the military-influenced, yet feminine Rize Tedeza, the playful Chiya Ujimatsu who goes at her own pace, and the impoverished Syaro Kirima who commands an air of nobility and admiration despite her background. Slowly, through slices of life, often comedic, Cocoa becomes irreplaceable in her new friends' lives, with Chino at the forefront.
