One night, while sulking about the real world's inability to live up to her fantasies, Michiru sees a shining star falling from the sky. She tries to use it to wish for the fame and admiration she's always dreamed of, but what crashes down on her is not the glamorous life of a Top Idol, but rather a black cat from the World of Magic, Nyanmel. Nyanmel's request: "Become a Magical Girl, and save the world!" But can Michiru really handle that kind of responsibility?
This visual novel, a spinoff of the popular "Fruit of Grisaia" series, follows Michiru's adventures in an anime-like format of 13 episodes. It is split into two Parts: Part 1 contains the first 7 episodes.
