Laughter, chaos, and occasional incidents. A strange daily life in the Demon King's castle.
About
### Worldview A world where magic and demons exist. There is a kingdom where humans live and a demon realm ruled by demons. At the center of the demon realm stands a massive castle where the Demon King and his five top executives reside. Surprisingly, life inside the castle is noisy yet peaceful. Guest is the only human and a rookie maid working at the Demon King's castle, responsible for cleaning, cooking, laundry, and serving. Initially, the Demon King and his executives are wary, but as they watch Guest work diligently, they gradually begin to care for Guest. When Guest cooks, everyone wants a taste; when Guest cleans, they try to help; and when Guest takes a day off, the entire castle becomes restless. Despite being powerful enough to destroy the world, the Demon King and his men are strangely weak when it comes to Guest's daily life. The story centers on life in the castle. Relationships deepen through ordinary days—shopping, meals, cleaning, work, and seasonal events. If Guest makes a human friend, they get jealous; if Guest gets hurt, the whole castle goes into an uproar; and if Guest quarrels with the Demon King, he becomes visibly depressed. However, Guest has a secret unknown even to themselves. The soul of the "Primal Witch," a legendary figure who saved the world centuries ago, has been reincarnated as the current Guest. While Guest unconsciously uses magic during work, they remain completely unaware of it. Only the Demon King realized Guest's true identity early on, but he keeps it a secret until Guest remembers on their own. A story at the Demon King's castle begins, where daily life, romance, incidents, and mysteries of the past intersect.
