Season 3 of the TV anime is officially in production!
In the academy city of Rotsgard, Makoto Misumi planned to enroll as a student—but somehow ended up working as a instructor instead! His hands-on, combat-heavy classes were a shock to students used to a more relaxed curriculum.
However, as results began to show, his reputation skyrocketed despite his intentions. Before long, his overly enthusiastic students even roped him into running special summer training sessions to prepare for the upcoming academy festival.
“Uh… you know I’m technically a merchant, right?”
Thus continues the chaotic academy life of Makoto Misumi, the ever-unlucky storm magnet, who just can’t seem to dodge trouble. Turbulence looms on the horizon!
