Beautiful girl Yuka is offered as collateral for her parents' debt and sent to serve at a notorious pleasure quarter. Despite her pure heart, Yuka finds herself tormented both physically and mentally in this harsh environment. Treated like a female prisoner, she is bound with hands tied behind her back and forced to hug a stone while subjected to water torture, then bound at wrists and ankles and hung upside down for more water torture. Her hair is tied up as she's placed in a reverse shrimp bind, then spread-eagle suspended and flogged with a bamboo whip. Coarse ropes wielded by the mad, candle-lit figure of TENMA tear through the darkness, tightly wrapping around Yuka's pale, translucent skin. Driven beyond her limits by the intense torment, Yuka escapes from the brothel only to be sold off to a holding house, where the tense narrative unfolds. "Broken Courtesan: Kobalt Rope Pimp," brought by the solitary master binder TENMA Haru and Reiwa's SM queen Yuka Tsubasa, forges new boundaries through their unique combination. Please note that the runtime listed on the DVD package differs from the actual main feature.
