This one gets you with the apology. Mui collapses on campus in a uniform nobody recognizes, says sorry before she explains anything, and that one accidental touch drafts Takeshi and Kurumi out of their fake-couple normal life and into a magic war they never asked for. Madhouse keeps it clean and restrained, no beach episode bailout, no harem shuffle, just a kendo kid learning that his own brother stands on the other side of the line. The problem is the rhythm: whole episodes idle at the academy, then the plot sprints through developments that deserved three times the runtime, and the finale walks off mid-sentence with almost nothing settled. Fans stay because the premise is genuinely good and the tone never winks at you. You will finish episode 12 staring at the credits, waiting for a second season that never came.

Takeshi Nanase thinks he knows his life: high school, a fake dating arrangement with his childhood friend Kurumi, and nothing particularly remarkable. That certainty shatters when Mui Aiba collapses on campus in an unfamiliar uniform. She's a magician, and she accidentally turns Takeshi into one too. What he believed was a single reality splits into two, one for humans and one for magic users. Most magicians want to live peacefully beside ordinary people, but the Ghost Trailers are ready to use violence to prove magicians are superior. Takeshi, Kurumi and their friend Kazumi, all newly gifted with magic, enroll alongside Mui at the Subaru Magic Academy to learn to control their powers. Hunted by the Ghost Trailers, they must grow stronger and stop a second great magic war from breaking out. The result is a fantasy action series built on modern magic.
