Background[]

Ria Minase lived with her big brother since their parents' death. One day, Takaharu died due to medical error, but Ria brought her brother's corpse to their home and lived with him for one year.
Soon after she realized that her brother, who “lived” by her side, was dead all this time, she attempted to commit suicide by being hit by a train. Just before she tried to, Kiryu Kusakabe, who was passing by during an out-of-body experience, stopped her and agreed that he was indeed a devil when Ria asked.
After Ria and Kiryu Kusakabe met, she decided to change her name to “Aria Kurenaino”, and opened a black magic agency called “The Crimson Mansion”.
