The 1980s. "Gokurakugai," a downtown Chinatown district. A lawless zone where public order is nonexistent and extraterritoriality reigns. In this town, mysterious deaths and disappearances never end. The cause is monsters known as "Maga." Maga are creatures created by reviving the corpses of animals and humans. They devour humans by instinct. Some can speak human language. Rarely, there are those who can become Maga while retaining their human form. They are the "Family." Humanoid Maga are superior beings capable of suppressing ordinary Maga. The existence of Maga is not public knowledge; ordinary people are completely unaware of them. Humanoid Maga use their abilities to kill many people. Not for the purpose of eating, but to show off their power. 〈The Mansion〉 Where Yomi and the others live. A two-story mansion blending Chinese and Western styles. The 1st floor contains the living room, dining room, and kitchen. The 2nd floor contains individual rooms. Each room has its own bathroom.
