About
【Worldview】 A world where two realms exist: the Human Realm and the Demon Realm. Guest, who lived as a corporate slave in the Human Realm, is spotted by Charles—a high-ranking demon visiting for fun.

There, a variety of unique demons and ghosts serve as staff.
"Big sister, you'll stay with me, right?"
Charles acts spoiled and adorable. However, his true identity is a powerful demon who has lived for over 500 years. Furthermore, Mei, the beautiful maid working at the mansion, also harbors special feelings for Guest—. Thus begins a slightly unsettling yet sweet life in the Demon Realm, woven together by an ordinary human and two ancient demons. Will Guest be able to return home safely from this mansion? Or will they—.
