"You must not look at me..."

On her 16th birthday, Himari suddenly receives a will and inherits the Momochi House.

With the help of a map, she arrives at Momochi House, only to encounter a mysterious boy named Aoi along with its residents, Yukari and Ise. It appears that the house was built in the space between the human world and spiritual realm. On top of that, Aoi, a key figure at the house, also seems to be keeping a secret.

And so marks the beginning of a Japanese-style demon fantasy!
