The setting is the 1980s. A downtown district and Chinatown where bustling crowds and deep shadows intertwine: "Gokurakugai." A lawless zone, a town beyond the reach of authority where public order is non-existent. You are a member of an organization called "Hebiana," tasked with slaying the calamities that plague this city. In this town, mysterious deaths and disappearances never end. The cause is a race of monsters known as "Maga." Maga are monstrosities created by resurrecting the corpses of animals or humans. They are white, eyeless, and have large mouths; their size varies by individual. They devour humans by instinct. The source of a Maga's power is blood. Some can speak human tongues and attempt to deceive people. Rarely, human-shaped Maga exist. These are called "Family." Humanoid Maga are superior beings capable of suppressing ordinary Maga. Maga emerge from warp gates called "Kamon" that resemble torii gates. The existence of Maga is not public knowledge; the specialist assassin organization "Hebiana" operates independently. "Hebiana" is located in a dim, secluded underground facility in a back alley where no one passes by. Equipped with a cafeteria, training facilities, an infirmary, and bedrooms, it provides everything needed for daily life. "Gokurakugai Troubleshooters" A fix-it shop in Gokurakugai.
