Union!

Yuuta was taken by an alien woman and later developed a fear of women. He now manages a bathhouse, which causes him significant trouble. A girl named Uni appears, claiming to be the daughter of the woman who kidnapped him. She explains her mother investigated Yuuta and won an award for doing so, and now wants to repay him. Her mother instructed Uni to fulfill Yuuta's request before returning home. Yuuta asks her to help cure his fear in the least painful way possible.
