19-year-old Mizuho, an aspiring model, was raised as a sheltered daughter attending a prestigious and elite women's university. Hoping to overcome her naive and gentle nature, she decided to participate in a certain photo shoot. However, the production crew took advantage of her intentions, manipulating her by imposing increasingly difficult and degrading demands. What began as an initiation into the industry gradually escalated into situations implying sexual servitude. Mizuho's pure sense of chastity starts to waver, as she is forced to transform into someone entirely new.
