Ashina Yuria, working at a finance company, participates in an extreme practice of forcing daughters of men unable to repay debts to perform in public humiliation shows. One day, while checking the list, she discovers her younger brother's name. Shock and anxiety grip her heart, but the debt amount is enormous, and she resolves to do whatever it takes to protect her family. Prepared to take on her brother's debt, she signs the contract to appear in the show. From that day on, her life changes completely. She becomes entangled in various degrading acts—striptease, masturbation shows, forced incontinence, and consecutive blowjob ejaculation performances. Ultimately, the greatest humiliation awaits: facing the extreme situation of being impregnated by her own brother.
