After a serious leg injury forces Shiho to retire and become the team manager, a new advisor named Inose (with a terrible reputation) enters their lives. He blackmails them with compromising evidence of Reira, forcing Shiho to agree to humiliating conditions — including wearing a remote clitoral vibrator to school daily and sending proof photos — to protect her friend.

Virgo Note (Balgo/Bargo/Vargo Note), the Empire’s most powerful magical swordswoman and feared as the “Sword Demon,” is cursed by a succubus during battle with the “Breeding Demon’s Seal” (or “Pregnancy Demon’s Curse Mark”/”Hermaphroditism Curse Mark” in some translations). This curse transforms her body to require massive amounts of semen to survive and eventually break the seal, turning her into a being dependent on sexual essence. Desperate and on the advice of her close friend, the supreme sorceress Elysia Heart (Elicia/Elisha), Virgo makes a radical choice: she quits her warrior life and debuts as an adult video (AV/porn) actress to gather the necessary “semen quota” through filming scenes. In her first raw experience on set, the once-tough, combat-hardened heroine exposes her voluptuous body to cameras and multiple men, facing lustful gazes and intense acts. She starts with deepthroating, paizuri (titjob), and progresses to raw missionary and doggystyle pounding, culminating in a massive overflowing creampie that floods her womb. The overwhelming pleasure awakens her suppressed feminine and lustful side—she begins to enjoy it, begging for more as she embraces her new “mesu” (female/submissive) nature to combat the curse. The episode focuses on her awkward yet explosive debut, humiliation turning to acceptance, and the start of her quest in the adult industry while discovering hidden desires.

In a sterile laboratory, dedicated researcher Marie sighs in frustration as she observes her motionless homunculus (an artificial humanoid/automaton) lying unresponsive on the bed—no signs of life or progress despite prolonged efforts. Sponsor Leon enters energetically, reassuring her it’s just the beginning. Ignoring protocols and observation logs, he approaches Marie intimately—caressing her while she kneels and performs oral on him. Their affair is portrayed as a repeated “mistake” born from accumulated stress in the high-pressure research environment. The scene escalates to passionate, intense sex: Marie’s voluptuous breasts sway as Leon penetrates her vigorously from below (cowgirl/reverse positions implied), pounding her fleshy buttocks with raw energy. She fully surrenders, lost in pleasure and oblivious to surroundings. Unbeknownst to them, inside the observation chamber, the doll-like homunculus suddenly opens its eyes—hinting at awakening triggered by their act, setting up potential future corruption, involvement of the automaton, or “mad love” themes involving artificial beings. This episode introduces a sci-fi/alchemy-themed setup with married woman infidelity, workplace stress-relief sex, and a twist of awakening artificial life through human passion/depravity.

Sylvia (or Silvia/Sylvia), an ordinary sheltered girl living alone deep in the mountains, is visited by a man named Steve. He takes her to the remote border city of Elanberg (or Elanbelk). Without understanding why, she is suddenly pushed down and roughly raped by him, losing her virginity in a traumatic first experience. Despite the shock and pain, Sylvia soon feels a mysterious power surging through her body—she has unknowingly awakened a hidden talent for alchemy, powered by absorbing semen as spiritual/energy source. Entrusted with developing and revitalizing the struggling town using her new powers (to atone for her father’s corruption or fulfill a contract replacing her missing mother), the novice big-breasted alchemist must now collect “vital essence” (semen) from men in the city. This fuels miraculous spells that improve infrastructure, agriculture, and daily life for the residents. She realizes with dread (and growing reluctant pleasure) just how many men she’ll have to take inside her to accomplish her mission, marking the start of her erotic town-building journey filled with sex in various settings.
