Misa walks into a haunted garden where people keep choosing death, and the hotel owner expects her to fix it with a price tag. She doesn't hesitate. What starts as a clean transaction, black magic for cash, becomes something that costs more than money, because the spirits aren't just angry, they're drowning in the weight of their own execution. This OVA refuses the comfortable horror that lets you leave untouched; it asks what it means to carry someone else's despair when the only tool you have is power.
Kuroi Misa accepts an unusual job offer: a luxury Japanese inn is plagued by inexplicable deaths. Guests hang themselves in the garden with no rational explanation, and the owner is desperate for answers. What makes this case different is the location's dark history. The ground beneath the hotel was once an execution site, and restless spirits linger there still. Misa, a high school girl with knowledge of black magic, sees an opportunity. She agrees to perform a ritual exorcism, but her price is steep: ten million yen. What unfolds is a supernatural confrontation where ancient curses meet dark incantations. Misa must navigate the boundary between the living and the dead, using forbidden magic to break the cycle of death haunting the garden. This OVA blends occult horror with the claustrophobic dread of a haunted location. It's atmospheric and unsettling, built on the premise that some places can't be saved by conventional means. The tension comes from whether Misa's dangerous methods will succeed or only deepen the spiritual corruption festering beneath the hotel's elegant facade.
