In a world at peace 15 years after the defeat of the demon lord, Kotone Kazairo, a newly graduated mage, moves to Dali—the royal capital of the Kingdom of Actus—to start a new chapter in her life. To find a place to settle, the 16-year-old visits a real estate agency called Rent Plan Guide (RPG). There, she meets its staff: the pragmatic priest Rufuria, the tomboyish warrior Rakira, and the adorable demihuman Fa. Coincidentally, Kotone is also set to work at RPG Real Estate and wastes no time learning the business from her coworkers. With many housing options available to suit the varied eccentricities of its diverse clientele, RPG Real Estate strives to deliver perfect matches for clients' specific needs, though it is not always an easy task. Even so, Kotone and her colleagues are determined to bring smiles to the faces of their patrons—one home at a time!
