For some strange reason, Ai follows the two, and is drawn into a world of bondage and rough sex. The experience transforms the girl, who embraces the lifestyle, and a weird but romantic relation with a man she is drawn to.

A reclusive young man and his younger sister live in a mansion together, where the young man frequently hosts sex parties every night, which he watches in his room via a network of surveillance cameras.

Winter Swimsuit With a subtle BDSM premise, a teenage couple has sex in what seems to be a closed public bath house at night in the middle of winter.

The episode begins when a young blue-haired woman is shown having sex with a group of weird men, afterwards they throw her into an oubliette where she then emerges as a butterfly. 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, then thrown down the same oubliette from the beginning of the episode, and emerging as butterflies.

The story begins when an ordinary girl named Marino Okura-(a virgin) is being chased by two young men who are revealed to be human traffickers. After getting captured, she is then shown in their car nervous and scared. When she attempts to escape, she is pulled back and brought into the estate of 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".

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 (Momomi and Haruka), 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.
