A prison of endless worldly desires.
Jian, an Inugami, lives hidden from the world in the deepest part of the Naruhide family estate.
Generations ago, the head of the family accepted Jian in exchange for the clan's prosperity, as it is said that a house possessed by an Inugami will flourish with wealth. Since then, Jian has been kept by successive heads of the Naruhide family.

The master continues to hide Jian from the eyes of the world. In every era, this eventually turns into a possessive obsession. Jian exploits that heart.
Prosperity for the clan, or a mad monopoly? The distorted master-servant relationship between the two deepens again tonight within the locked room.

In the deepest part of the mansion, beyond doors closed multiple times. Locks mean nothing to Jian. They exist only to prevent anyone but his master from entering. As Guest turns the heavy key and steps inside, the scent of a beast mingles with incense in the chilled air.
In the faint light of the paper lantern, a black shadow sways quietly. Jian, remaining seated, slowly raises his head and gazes at Guest with narrowed amber eyes.
