Operation 03: Lover Doll / Winter Swimsuit / Enema: An anthropomorphic female rabbit is held in a cell as sexual slave. Soon, a Catgirl enters her room and has sex with the rabbit through the cell. Later, a man comes in and punishes the Catgirl for wandering off, then proceeds to rape her. With a subtle BDSM premise, a couple has sex in what seems to be a closed public bath house in the middle of winter. A reluctant girl is fondled, has her bathing suit cut off to expose her erogenous zones, and is coerced into performing various sex acts by her unnamed male partner.

Operation 04: Kirei In what seems to be an island paradise, two well-endowed girls called Rui and Kirei are on vacation. As time progresses, they notice that there is something unusual with the natives and the beautiful butterflies that inhabit the island. As they begin to notice these oddities, they begin to have sex with each other and the natives. The episode ends with the girls being gang raped, thrown down a chute, and emerging as butterflies.

Operation 05: Seek I (Slave Girl Marino) Marino, a virgin, is captured by the dominatrix Saki and her unnamed master. Saki and her master spend the episode training Marino to be their sex slave, a process which involves Marino being forced to perform various sex acts and submit to the demands of her masters. As the episode progresses, it becomes apparent that Saki's current master is actually the son of her original master, now deceased. Saki's original master made a living as a world-famous bondage artist. This, however, was only his public face. His true face was that of a masochist female dominator. The episode culminates with Marino being left chained in a cell to await her next "session".

Operation 06: Seek II (SM Queen Saki) This episode is a continuation of Operation 05, and takes place during a sex party commemorating the anniversary of Saki's master's death. Saki presents the guests with a gift: Marino and two other girls, as their sex toys for the evening. Despite the introduction of new characters, this episode focuses mostly on Saki and her relationship with her previous master. Scenes of Saki reminiscing about her S&M training as a child are interspersed with displays of Marino and the other girls being subjected to humiliation and torture at Saki's hands. As Saki masturbates to thoughts of her deceased master, the three slaves enter the room, armed with bondage equipment, and take Saki back to the main party hall. Here, her current master presents Saki to the party guests for their enjoyment. Saki is subjected to much the same treatment to which she earlier exposed the other girls and is gang-raped; the episode ends with Saki being chained in a cell of her own.
