The heroine, Gerda, is living in a small village. Along with her childhood friend, Kai, she has a peaceful life surrounded by the beautiful flowers they love. Until one day, Kai obtained a magic mirror believed to have the "power to grant wish". The people who are present at the time are Orva, a servile and fragile coward; Craes, a cheerful chef apprentice; and Aje, a traveling swordsman with no sense of direction.
When they take a closer look, the mirror suddenly shatters into pieces. They are swallowed by a blinding light and lose their consciousness. By the time they open their eyes, they find absolutely no trace of the broken mirror pieces. They don't understand what just happened. Nothing seems to happen to them either, and so they go home for the day.
However, starting from the next day, a certain change appears in their bodies—!?
