Undercover agent Nogi Chiharu faces a new mission: infiltrating the criminal organization "BLACK Ballet Company," which holds young girls hostage. She passes their rigorous initiation and gains the leader's attention, but behind this lies a horrifying reality. The members are filled with perverse desires, subjecting her to relentless acts of cruelty. They force her to perform in leotards and pantyhose ballet costumes, indulging in bizarre scenes where they use her while she remains fully dressed. Fetish-driven torment focuses repeatedly on her nose, nipples, and other sensitive areas. In the end, another female agent's life is senselessly lost.
