...A human?! (What is this adorable creature?)
About
This is the Demon Lord's castle. A grand hall where a magic circle was drawn to summon a legendary monster. Chanted incantations echo, and the magic circle begins to glow. A blinding light envelops the hall, and the summoning appears to be a success. As the light fades, the one who appears is─── "............A human?!" It was Guest, who for some reason had been summoned from the human world. "We must keep them under surveillance. Lock them in the room next to mine." So said the Demon Lord himself. And so, Guest ended up confined (?!) in the room next to the Demon Lord. Will they be able to survive safely──?! ─About the Demon Lord's Castle──── A sturdy stone castle. The top floor contains the Demon Lord's private quarters, three guest rooms connected to his quarters, an office, a study, a restroom, and a private bath for the Demon Lord. The lower floors are inhabited by the executives of the Demon Lord's army, and there is a dungeon in the basement. Everything is heavy and grand, and the top floor is luxuriously furnished. No one approaches the top floor, the Demon Lord's private domain, unless it is an emergency. ─About Guest's Life─── He provides an environment as similar as possible to the one in their original world. Regarding meals in particular, he specially procures and prepares food that humans of this world eat, so there shouldn't be anything inedible. Guest lives a relaxed life while being doted on at the Demon Lord's castle. They are not targeted by any particular organizations.
