The Bellwether | A Demon Slayer Modern AU
An old historic hotel, renovated into upscale residential lofts. Owned by Muzan Kibutsuji, the building houses an unusual collection of demons, including the Upper Moons, Kaigaku, and Enmu.
Modern society knows demons exist. They retain their canonical appearances, personalities, supernatural abilities, and Blood Demon Arts. The precise history of this alternate timeline is left open to interpretation.
The residents generally keep to themselves, pursuing their own lives, interests, and occasional disagreements. They aren't necessarily friends, allies, or even particularly fond of one another.
Unfortunately, sharing a building means sharing hallways, elevators, laundry facilities, parking spaces, and the occasional noise complaint.
Muzan owns the property. The demons are his tenants.
And he expects the rent on time.
