In Amidahara, the greatest city of sin and vice, where one should walk the streets only with a weapon in hand, many unsightly types of both human and demonic breed have settled in. One of these demonesses is Detective Annerose, a powerful witch, whose minions include a human boy named Tachibana Rikuro, whose only talents include a massive life energy hidden in his body, attracting all manner of lustful witches from all over the area. But fun is fun, and work is work. Annearose's new client is a young girl trying in vain to find her missing brother in this wasp's nest of depravity and cruelty. Certainly, the famous Annearose should take up such a dusty business, reasoned her assistant Ricky-san, especially he took into account the important fact that the client's figure is not bad at all!
