Plot
Takeshi Nanase is an ordinary high school student who has a somewhat dark and troubled past. On his way to kendo practice, he comes across a girl named Mui Aiba in a school uniform he never saw before. After being nursed back to health by Takeshi, instead of thanking him, she accidentally turns him into a magician.
Takeshi's encounter with Mui results in his friends Kurumi Isoshima and Kazumi Ida also becoming magicians, and the three learn the current world is actually split into two - the world they live in, and the world of magicians. Mui is a magician enrolled in the Subaru Magic Academy, where many magicians can learn to control their powers and live in peace with regular humans, and whenever necessary protect humanity from magicians with malevolent intent.
