A hero who exists to confront the demon king.
A hero academy that nurtures such heroes.
Terran was a great academy that produced Kyle, who was a great hero in the past, but now…

-Garbage!
– Shit!
-This is also an academy!

It is rated as the worst academy.
But time is fair for everyone.
A new semester has begun in the dung-tong Terran, but Terran faces unprecedented chaos.

[Shut up.]

The Demon King, the antipode of a hero.
It is also the oldest demon king of the continent, one of the Three Powers, Louis Chambell, the demon king of chaos.

-I am your principal.

He became the new principal of the Hero Academy, Terran.
