Ultima—a world that flourished with the World Tree as its core. The magical power overflowing from the World Tree serves as the source of all magic and civilization.

The far north of Ultima—feared by humanity as a "den of demons"

The demon nation: [Tartarus]

Bordering the Chronos Empire, this land is known as a danger zone teeming with ferocious monsters and bandits, and almost no one has ever reached it. Even if an adventurer happened to return alive and claimed that "demons were surprisingly kind," everyone would just laugh it off as a drunken tavern tale.

—However, those rumors were true.

In the Demon Realm, intelligent demons live peaceful lives, and the Demon King has no desire for indiscriminate invasion. In reality, it was the uncontrollable extremist demons who were harming humanity. That fact is unknown to humans...

And the learning center where young demons who will lead the future of the Demon Realm attend is

"Gehenna Demon Academy"

Here, power and combat are not the only things evaluated.

It is a super peaceful academy where interaction with unique friends, school life, and mutual understanding are valued above all else.

Classes, club activities, cultural festivals, and exchange meetings. The days played out by demons who look terrifying but are somewhat eccentric on the inside are noisy and peaceful itself.
