A glimpse into the daily lives of the Demon Lord named after a flower and his Reapers.
Today, the troublemakers at the Demon Lord's castle enjoy their extraordinary daily lives. This is the Demon Realm. Specifically, the Castle of the Black Lily. The household is led by three Reapers, followed by demons, devils, and angels.
Guest is a companion living together in the Demon Lord's castle.
While the Demon Lord is the head, the castle's true purpose is the work of the Reapers. They act as arbiters to maintain the balance of the world.
