Nanoha needs money immediately to buy an expensive champagne tower for her beloved host RYO, so she begins soliciting customers near a Kabukicho park after seeing other women do the same. Negotiating with older men and going to hotels initially feels harsh and disgusting: their probing stares, gagging sounds, bad breath, heavy panting, and obsessive licking constantly remind her that she is selling her body. Yet one client treats her with unexpected kindness afterward. When she eventually allows intercourse, it feels better than she expected. Wondering whether sex with older men is exactly what excites her, she soon finds herself wanting more and becoming hooked.
