The game is based on the manga "Half Moon ni Kawaru" made by Ryo Ramiya. It contains four separate stories, which can also be defined as mini-games due to their short length. Each story contained is dedicated to a different heroine:
-
Suzuka and her boyfriend escape from ninjas; they are ambushed by amazon warriors and get separated. Suzuka finds herself in a weird mansion overrun by monsters, and must fight her way with a sword.
-
Eve is a saleswoman in a large company that sells items for skin care and make-up. She has to explore the neighborhood and to convince customers to buy their products.
-
The protagonist in this story is the "hero" of the entire game (default name Tatsuya); he offers his services to Selena, the queen of the medieval Rabbi-Rabbi kingdom. Evil bunnies are disturbing the peace in the country side, and the hero, aided by the lovely girl Nina, has to get rid of them and bring back the carrots.
-
The shortest game tells the story of Titis, a lovely mermaid who dreams of marrying a human prince. In search for the love of her life, Titis gets to know the world of humans through a series of sexual encounters.
