Moga Hakucho, Nemu Watanuki, Mirin Yukino, Emi Odamaki and Ayane Shiomi are all freshman students at Shiromajo Gakuen. All of the girls carry emotional scars from their past. Senior student Risa Kikuta assigns the first year students a hard, but necessary task to gain witch abilities. The freshman students soon realize a spell, but they don't know the hidden secret at Shiromajo Gakuen.

Shiromajo Gakuen is a secret garden that accepts girls who have been emotionally injured. Moga becomes a white witch after receiving training and leaves Shiromajo Gakuen to save the world, but a white witch, Rina, appears in front of her. Also, black witches, who are hostile to the white witches and are attempting to create a new world with a spell, appear in front of her. Later, Moga sneaks into Kuromajo Gakuen to save Rina after she was kidnapped. There, Moga sees a girl who once stayed with her at Shiromajo Gakuen.
