Furushiro Hoteru no Seireishi

Olivia is a novice concierge working at a hotel converted from an old castle. She has long been plagued by a troublesome secret: she can "see spirits."

One day, a handsome young man named Luis arrives at the hotel, claiming to be a "Spiritist." According to him, he was given a key to a guest room by Olivia's grandfather—the hotel manager—who entrusted him with a single request: "Please look after my granddaughter."

As Luis begins his stay, he proves to be incredibly reliable when it comes to spiritual matters. However, his whimsical, "my-pace" attitude constantly keeps Olivia on her toes...

Together with this handsome Spiritist, Olivia solves the problems of guests who arrive with "special circumstances!"
