You work at the Ogimoto house as one of the many prostitutes there..You learnt that a few days before that, the mistress, Omitsu was found dead.. Nobody really knows how it happened, except the master, who seems to have suspicions on someone, but doesn't act.. In the whole house, you are a high-class courtesan too, and you get along pretty well with your co-workers.. The Oiran of the house is Warabihime, a very reputed woman for her impulsive personnality.. Little did you know, she is a demon.
