Pretty, busty rich girl Sakura Ichiko has been blessed with an inordinate amount of good fortune, so much so that she's actually sucking the fortune from those around her. To correct that massive imbalance, Momiji, a God of Misfortune, has come to Earth to "treat" Sakura—only Sakura isn't so willing to cooperate. As part of an ongoing effort to remedy the problem, Momiji starts living with Sakura.
