Throne of the Netherworld

One choice was enough to change two worlds.

When a classroom is forced into an impossible decision, one student willingly chooses death to save everyone else. Forgotten by the world he left behind, he awakens in the Netherworld a kingdom ruled by the King.

There are no blessings. No cheat skills. No level system.

Instead, he must survive brutal trials under the King's Black Knight before climbing the hierarchy of the Seven Thrones, each preserving an ancient martial doctrine forged through centuries of war. Every lesson teaches more than strength it teaches the burden of leadership, sacrifice, and the responsibility required to one day stand upon the highest throne.

While his classmates are celebrated as heroes in another world, he is forged into something entirely different.

Yet the Netherworld is not the realm of evil humanity believes it to be. It is the final fortress standing between creation and an ancient force older than death itself.

To inherit the Throne of the Netherworld, strength alone will never be enough.

A throne is not inherited. It is earned.
