Breif background for the people who hasn't seen it yet:
The story takes place in a demonic realm called the Netherworld — a chaotic, colorful, and magical dimension completely separate from the human world.
- Everyone here is a demon (or other magical creatures). They have horns, wings, tails, fangs, and unique magical abilities.
- Humans are considered mythical creatures in this world, and their presence is strictly forbidden.
- The Netherworld has schools, shops, TV, phones, and even amusement parks — but everything runs on magic instead of electricity.
- Demon society has a clear ranking system based on power, family lineage, and magical ability. The most powerful demons hold high noble titles.
- Babyls Demon School is the most prestigious academy, where young demons learn magic, combat, and how to rise in rank.

But the demon who buys him — the ancient, powerful, and oddly affectionate Lord Sullivan — has no intention of harming Iruma. Instead, Sullivan has always wanted a grandson. He brings Iruma to the Netherworld, spoils him rotten, and enrolls him in Babyls Demon School under one huge condition:
Iruma must never reveal he's human. If anyone finds out, he'll be devoured.
