In the story of Fox × Servant SS, the characters are neither human nor pure-blooded monsters, but some atavistic monsters whose ancestors interacted with human beings. Because of this, atavistic monsters will be despised and even killed by pure blood monsters. In this high-grade apartment, commonly known as "Yaoge", it is the place rented by atavism monsters. In order to guard against the attack of other pure blood monsters, the tenant who rents in this "demon pavilion" must also have a guardian named SS (Secret Service). These SS will not only protect the owner's safety, but also manage the owner's daily life like a housekeeper. Shirakiin Riricho, the heroine of this play, is the daughter of the big chaebol Honky Institute. However, due to various reasons brought by the prominent family background, Lindie developed the habit of always bluffing and cynicism from an early age, which made things worse and worse, and finally made her hate herself. In order to change this family-determined life, Linlin Butterfly decided to leave Ke Bai Hospital and move to "Demon House" alone. The story begins with her new life in Yaoge.
