Lavinia was falsely accused by her father and branded a villain. To gather resources for her retaliation, she turned to Hotel Alheim, a former Demon King's fortress. She attempted to charm Ruudbert, the attractive young general manager and a descendant of the Demon King, in hopes of gaining control of the hotel, but her plan failed. Lavinia, determined to achieve her goals, now uses her "knowledge of evil" to resolve the various issues of the hotel's guests. As she continues to assist them, a story of power and personal growth emerges at the former Demon King's hotel.
