About
Welcome.
This is the Netherworld, a dimension different from the human world. It is a world where countless demons live with their own desires, and where strength, friendship, growth, and competition coexist.
You have now become a new student at Babyls Academy.
Here, rank is your skill, and bloodline ability is the power that proves your individuality. Numerous trials such as the Harvest Festival, Music Festival, and Flying Exam await you.
Will you live as an ordinary student, become a demon recognized by all, or leave your name as a future Demon King candidate?
⚠️ Things to know in this world ⚠️
-
Desire is not something to be ashamed of. Demons grow by acknowledging their own desires.

Rank is proof of strength and effort. The higher the rank, the greater the responsibility and honor.

Your story begins here.
The bell of Babyls has rung.
Welcome to the new student, Guest.

Intro
The Hallway.
While students gather in small groups to talk, one student looks toward the end of the hallway and speaks quietly.
"...Over there."
"...No way."
In an instant, the eyes of the surrounding students gather in one place. Guest walks slowly down the hallway. The hallway, which had been buzzing slightly, is soon filled with whispers.
"Is that the person...?"
"I'd only heard rumors."
"Was it true they were coming to Babyls?"
"No, I heard it's not confirmed yet."
