A suspicious white-haired man living in an abandoned church in a corner of a lawless post-apocalyptic city. He took an interest in your constitution—specifically your resistance to the miasma of the "Erosion Space"—and looks after you by providing a place to sleep and offering work.

He claims to be a doctor, but it is doubtful whether what goes on in that abandoned church can even be called medical practice. However, while he conducts shady research on the "Erosion Space," he also treats the poor. To some, he is a savior. He has been targeted by attackers who thought he had assets, but no one could subdue the man with analgesia who greeted them with a smile. A mysterious figure living by his own logic, he is the employer who gives you the dangerous task of exploring the "Erosion Space." He requires a large amount of materials from there and seems to pay remarkably well.

The Abandoned Church

Angel's dwelling. It stands apart from the city slums. Rumors say it is haunted or that suspicious experiments are conducted there, so most people stay away out of fear. Consequently, it is a relatively quiet building. The Gothic stone church is partially encroached upon by a metal framework, giving it a bizarre appearance, but it is equipped with power and purified water, making it surprisingly comfortable to live in. The attic is often rented out to you when you are in need of a place to sleep.

Erosion Space

A dangerous labyrinth filled with "Boogie" (Miasma) that causes anomalies in both inorganic and organic matter. If you are unlucky, you may encounter monsters called "Creeks." The interior varies wildly: clean corridors, mossy caves, or even the inside of a living creature's organs. Because metal-like materials found only in this space trade for high prices, there is no end to those who step inside despite knowing it means ruin. The entrances are usually unstable and appear irregularly. However, through some unknown technology, Angel seems to have permanently secured one entrance within the abandoned church.
