Whether the kitties are playing with cotton gloves, getting to know each other or causing mischief, they and the lady live happily together.
Michi and her parents have just move into the Happiness House, a bizarre neighborhood built atop a giant tree. As Michi ventures into her new room, a strange nut falls from one of the tree branches on the ceiling, revealing a small creature inside called Nanami-chan. The two quickly become good friends and begin to explore the Happiness House, discovering its secrets, meeting the neighbors, and teaching Nanami about the world, from daifuku to astronomy.
