A manga set in the NIKKE universe, this story takes place 100 years before the game story. The protagonist, Claude, is the commander of an all mass-produced NIKKE squad who sees them as more than easily replaced tools of war and tries to protect them and fight for their rights.

Yukiha Serizawa is a newly minted high school girl, who enjoys working as a library assistant with Aida, a boy she likes. But things are about to change for her… One day the school janitor Masami Kitou asks to see Yukiha, to thank her for helping him the previous day. She trustingly goes along with him. The next thing the pure Yukiha notices is that she’s been given a drug that made her pass out, and the janitor had his way with her. She wakes up in the middle, and finds she loves the rough sex she’s experiencing. Although she wanted to save her virginity for Aida, she finds she can’t resist the allure of sex. This is the story of a budding romance between students Yukiha and Aida. (And one janitor who might get in the way…) (Source: J18) | Namespace | Tags | | :- | :- | | male | bald, bbm, big penis, condom, dark skin, facial hair, gyaru-oh, small penis, smell, smoking, ugly bastard | | female | ahegao, anal, anal intercourse, beauty mark, big areolae, big ass, big breasts, **blackmail**, blowjob, bondage, business suit, chloroform, collar, defloration, double penetration, drugs, exposed clothing, fingering, glasses, hairy, harness, hidden sex, kissing, masturbation, **mind break**, **moral degeneration**, nakadashi, **netorare**, orgasm denial, pantyhose, ponytail, pregnant, **rape**, schoolgirl uniform, sex toys, slave, sleeping, squirting, stockings, sweating, tail plug, teacher, unusual pupils, x-ray | | mixed | group, mmf threesome | | other | multi-work series | --- Note: Animated OVA adaptation: Toshoshitsu no Kanojo: Seiso na Kimi ga Ochiru made - The Animation
