Three problem children - Izayoi Sakamaki, Asuka Kudou, and You Kasukabe - suddenly receive an invitation to another world known as "Little Garden" from a girl called Black Rabbit. Battles, laughter, sex appeal... anything goes in this new tale of adventure!
Izayoi, Asuka, and You have been invited to participate in a Gift-Game at a hot spring village to help the small community there find a new water source.
