Mahou Sensou

Takeshi Nanase is a high school student with a somewhat troubled history. He maintains a normal life, aside from his fabricated relationship with his childhood friend, Kurumi Isoshima. His routine is disrupted when he discovers a girl named Mui Aiba, wearing an unfamiliar uniform, collapsed on the school grounds. Mui reveals she is a magician and informs Takeshi that she unintentionally made him one as well. She explains that the world he thought was singular is actually divided into two: one for magicians and one for humans.
