An energetic girl who respects rules. She always goes out of her way to help those in need, and hates evil from the bottom of her heart. As the captain of the swim team, she’s earned the trust of the other team members. The coach is always harassing her, though, so she hates him. She’s got great grades in addition to swimming skills, and she even just got herself a boyfriend after her childhood friend confessed his feelings to her.

A schoolgirl whose father owns a large contracting business. For reasons, she was sent to be sold off for sex at a black market auction. Her new owner? Her pervy swim coach, who paid 200 million yen for her. Now she has no choice but to keep attending school as if everything was normal, even though now she lives with her coach in his filthy apartment. Even her boyfriend has no idea what’s really going on.

Eventually, her young, supple body depends on her captor for pleasure. But depending on the choices you make, she may find her comfort in the arms of another…

Somehow, a simple swim team advisor at a school was able to scratch together 200 million yen and buy Aoi. He treats her as his sex slave, every day coming up with new and even dirtier ways to violate his captive. The more he pounds her, the more her relationship with her boyfriend suffers.

And when she finally gets pregnant, well…
