Akio Yamane’s bloodline is cursed! Will his hot guardian deity break the curse…or merely his heart in the process?

Akio Yamane falls terminally ill, presumably from his family’s curse. Acting on his grandfather's final words, he accidentally summons a god who promises to cure him, albeit in a rather odd and intimate manner! Thurs begins the story of certain cursed families' strange and mystifying relationships with supernatural protectors.

Thanks to his grandmother’s trickery, high school student Tsumugi has been betrothed to Master Kurayori, the family’s guardian deity. Although Kurayori is rather miffed over the deception, Tsumugi is serious about his relationship with the guardian deity and about saving his home. However, as the two spend more time together, nothing romantic seems to develop. What’s an inexperienced high school student betrothed to a guardian deity to do?
