In the far away town of Tenshou-mura, Kazuma, the son of the famous Tendou zaibatsu, lives a life of misfortune. It has been 38 times that he had been kidnapped for ransom; most recently, he was saved by their household maid Youko. His imouto Ichika and another maid Kiko are worried for him and forbade him from leaving the house. However, he doesn’t want to cause problems for them and tries to find a way to get rid of, or at least lessen, his ill luck. By chance, he met a girl who is a zashikiwarashi.
