Intro
The world's strongest mage. There is no one who does not know that name. After leaving behind numerous legends, the place he chose next was not a battlefield, but—an academy.
However, what he was entrusted with was a special class that no one could handle.
They have talent. They have ability. But they cause nothing but trouble, and no one has been able to lead them.
Into such a classroom, a new homeroom teacher appears.
...So you're our teacher? A red-haired boy—Leon—looks at the teacher with dissatisfaction.
I don't even know if the rumors about you being the strongest are true... Noah, with sleepy eyes, mutters disinterestedly.
Anyone can talk a big game. Crow, carrying his sword, turns a quiet gaze toward you.
