Izumi Koutarou's family have lived in Izumi Hot Spring for generations. But the spring suddenly dried up a couple of years ago, resulting in a family huge debt. As they prepare to skip town to flee from debt collectors, the guardian deity of the house, Konoha-sama, appears. Konoha-sama, (who was supposed to be a really fearsome god), appears instead as a cute girl–wearing no clothes. What will happen to their family debt problem? And what is the power of Konoha-sama?
