Classroom for Heroes

The hero is a "super creature"!? Blade, a previous hero who battled the Demon Lord and lost all of his strength. As he desired, he should have logically been an average student, but the school he attended was actually a top-tier institution for hero cultivation? Of course, the students who attend are top-notch. While Blade was previously an "authentic" hero, he is now too heroic in terms of his "mind," "body," and "skills"!? He insulted the king in addition to destroying the majority of the school building during the practical class! He can even eat pork cutlet curry alone when the school is in a frenzy since the Dragon Clan escaped!? Now Blade begins the bizarre, wild, careless, and utterly unnatural "Loose cannon" life by acting like a "super creature"!
