SSNI-165 Akio, the undercover cop who was targeted by a ghoulish group for entrapment, Yoshizawa Akio

To overcome the trauma from a failed infiltration mission in the past, Akayu challenges herself to an undercover investigation as bait for molesters. Intending to catch an anonymous group of molesters operating on the dark web, she instead falls prey to the coordinated efforts of experienced molesters. They divide roles into wall guys, spectators, cameramen, and molesters, using aphrodisiacs in a clever strategy of encirclement molestation. In the confined space of a train, she has her handcuffs taken away and is restrained, forced into fellatio, gang raped... acts of utter cruelty take place.
