The first OVA adaptation of Sevengar's manga uses in-motion technology to recreate a dark assault world with adult campus athletics roles. After injury forces Shiho Amazuka from competition into management, new adviser Inose poisons the club atmosphere and blackmails her with evidence of Leila's “improper relationship.” Three conditions follow: wear a clitoral suction device every school morning and send proof; prioritize summons and orders without removing it; and prohibit intercourse or kissing, with social punishment if he violates the deal. Shiho plans to feign obedience, collect evidence, and destroy him after the final meet, but training draws her deeper.
