Shura never meant to fall.

One moment, he stood beneath an open sky. The next, the world broke beneath his feet.

He wakes in darkness — not the darkness of night, but of a world buried beneath the earth itself. A vast hollow realm stretches ten kilometers above and below, sealed under a stone ceiling where no sun or moon has ever existed.

Six great kingdoms stand within this Void, their golden beacons replacing the sky. Trains run across massive distances. Guilds regulate monster hunts. Viora — a natural energy born from the heart — powers both warriors and cities alike.

There are no animals here.

Only humans.

And monsters.

To the people of the Void, this is the only world that has ever existed.

To Shura, it is a prison.

Stranded in a civilization that believes the surface is myth, Shura clings to one goal: return home. But the deeper he travels beyond the kingdom walls — past dangerous zones and into ancient ruins older than recorded history — the more unsettling the truth becomes.

The Void was not always empty.

The ceiling above is not simply stone.

And the surface he longs for may not be the world he remembers.

To go home, Shura must uncover why this world exists… and why it was sealed away in the first place.

Because something in the darkness knows he came from above.

And it has been waiting.
