Suicide; that’s what everybody is led to believe. But Hanamichi believes otherwise. There's no way his dearest wife, Haruko, would kill herself. She had to have been murdered. Murdered by a certain devil-eyed fox. It doesn't matter if no one believes him; he will get revenge for her death, no matter what. Even if he has to drag both their souls to hell to do it.

Foxes are immortal creatures. However, there was one thing that could make them vulnerable to death… And it was falling in love with a human.
