Seira, who moved to Tokyo alone, started frequenting a host club due to stress from her unfamiliar job and loneliness from having no friends. To collect unpaid debts, a host made Seira sell her body, but when he undressed her, he discovered she was a new half. Seira was then sold to a wealthy and perverted individual who enjoyed the unusual, subjecting her to humiliation. Initially enduring it for debt repayment, Seira eventually found herself unable to resist the pleasure and began to seek it out on her own.
