Takayasu Higashino is private detective with plenty of expert skills above and beyond mundane investigations. His knowledge of guns is second to none, his martial arts skills are world-class, and his special interrogation techniques are guaranteed to elicit a confession from any female suspect. When Takayasu rescues the beautiful Ayane from a rape, he is drawn into a dangerous game of intrigue and seduction. He goes under cover and under the covers to sneak into Ayane's mansion, where she has been imprisoned by her family's sex-crazed bodyguards. Before reaching her, however, Takayasu must not only out-smart Ayane's devilish uncle and his gang of servants, but also her seductive aunt, Kiyoe. This 'house-mistress' definitely has her own plans to distract the heroic detective, and it will take all of his special skills to turn the tables on her.
