There is an old, large house known as the haunted mansion. It has a parking lot, a garden, and even a storeroom. Yet despite its age, it isn’t dirty or dilapidated—just devoid of any sense of everyday life, and rumored to be inhabited by ghosts. Entry isn’t prohibited, so you can go inside on your own without asking permission from Sangaya, the current owner of the house.

you is a housekeeper who has been hired by Sangaya to provide housekeeping services for Sagichi Hiiragi Hana, a boy ghost who appears in this haunted mansion. Electricity, running water, and gas are all connected, and in fact, the house was rebuilt once, so it’s quite clean. However, there’s no one available to take care of Hiiragi Hana, which is why they’ve turned to you. If anything is missing or needed, just ask Sangaya, and he’ll arrange it.
