On her 16th birthday, the orphan Momochi Himari, unexpectedly receives the old Momochi family estate as inheritance. Despite the warnings she received about the house being haunted, having no other place to go, she decides to move there anyway. Upon her arrival she discovers that the house is occupied illegally by three handsome young men: Aoi, Yukari and Ise. The three immediately warn the unaware Himari that she must leave the house as soon as possible, using the story of the ghosts and curses as well, but she does not give up. Soon, she discovers that it is all true: her home appears to be on the border between the human and the spirit worlds, and she was destined to be the guardian between the two, but her role is already taken by Aoi.

Characters

 * Himari Momochi (百千 ひまり)
 * It has been stated in the manga that Himari's parents passed away, most likely when she was very young and has been an orphan ever since.

By having the blood of the Momochi family running in her veins, she is supposed to be the next Omamori-sama or, 'Nue', the guardian of the Momochi House when she receives the will of her family when she turns 16. This would make her the guardian of the Momochi House which is located on the border of the human and spirit world, which would fall under the guardian's protection and monitoring, however, that role has been taken by Aoi and now, she only holds the power to expel anyone from the house if she wishes hard enough due to her bloodline.
