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.

Viora is a natural energy developed in the hearts of living beings. It enhances both physical and mental faculties and is unique to each individual's life force.


Personal Enhancement – Strength, speed, reflexes, intelligence, and perception can be heightened through controlled use. 


Communication & Resonance – Users can locate people, objects, or places by resonating with Viora. 


Teleportation – Among the rarest abilities, only possible with highly concentrated or compatible Viora. 


Machinery & Beacons – Extracted Viora can be used as power for large-scale devices, infrastructure, or signal systems. 


Viora can be extracted from monster hearts . Monster hearts often contain concentrated stores, making them highly sought after. Using too much Viora at once can destroy the user, either physically or mentally, depending on the intensity and duration. Extraction and application require training; improper handling is extremely dangerous. 


Each individual being possesses roughly equal amounts of Viora. The difference comes from focus, concentration, and skill—how efficiently one can use their Viora determines strength and capability. Poor focus or wasteful use reduces effectiveness, regardless of raw potential. 


Viora is not magic. It is a natural bio-energetic phenomenon. Stronger creatures possess purer and more concentrated Viora. Organizations and powerful individuals often hoard Viora for its versatile applications.
