One day, Cocoa arrived in a town for a work-stay program as organized by her school. There, she excitingly entered the café "Rabbit House," expecting to be able to cuddle rabbits, but instead she found the Kafuu residence, her new home where she will be staying. In this town she will meet her precious and important friends, a responsible, calm but cute girl named Chino, a tough and soldier-esque girl named Rize, a spacey and quintessentially Japanese girl named Chiya, and the ordinary but dignified Syaro.
