Working as bunny girls at a certain brothel are Meko, Kana, and Yuzu. Their routine is suddenly disrupted by the arrival of a new girl—Mayu, a busty, charming newcomer who instantly draws attention. Overwhelmed by her appeal, customers flock to her, and she quickly snatches the top spot from the three veterans. Filled with humiliation and rage, the senior girls frame Mayu by falsely accusing her of stealing sales money. Soon, yakuza enforcers arrive to collect the debt, and the shop manager pins the blame entirely on Mayu. Wrongfully convicted, Mayu is forced into becoming a sex slave bunny girl, plunging her into a hellish life of relentless sexual abuse.
