The world ended not with fire, but with silence. One hundred years ago, the phenomenon known as The Fracture tore reality apart. Entire cities vanished. Oceans swallowed nations.
Tokyo became the center of the disaster. The surviving districts became isolated kingdoms built atop ruins. Humanity lost its technology, governments collapsed, and history became myth.
Yet at the center of ruined Shibuya stood a sealed gate — untouched by time. A gate no one could open. A gate waiting for a key.
Eight clans emerged from the ruins. Each mastered one of the primordial forces left behind by The Fracture. The strongest among them became the Leaders of Yūgen.
Legend tells of an artifact forged before reality split — the Master Key. An object capable of opening every lock, every barrier, every dimension.
The Key was broken into fragments and scattered throughout the ruined world. When reunited, it reveals the path to the Origin Realm — the realm where reality itself was created.
- Many seek the Key for power
- Others seek salvation
- None truly know what waits behind the Gate
The Fracture revealed the hidden forces beneath existence. These are not merely elements — they are living laws of reality.
Every person possesses one essence. Only the chosen can wield multiple. Only one can master all eight.
The Gate created a system — a divine trial known as The Alignment Game. Participants summon manifestations of their elemental spirits.
- Battles between elemental manifestations
- Strategic contests of will
- Moral choices with lasting consequence
- Sacrifices that consume the soul
Each victory grants a fragment of the Master Key. Each defeat consumes part of the participant's essence. No one has ever completed all eight trials.
Eigetsu discovers the first fragment. Its appearance triggers ancient mechanisms buried beneath Shibuya. The Gate awakens.
Across the world, the other leaders receive visions. Each sees a different future:
- A world reborn
- A world consumed
- A world ruled
- A world erased
Realizing the Gate is opening, the leaders begin gathering. Not as allies. Not as enemies. But as rivals chasing destiny.
The Gate was never built by humans. It predates civilization itself. Behind it lies the Nexus Realm — a place connecting countless realities.
- Every myth
- Every timeline
- Every possibility
The Gate's true purpose was never protection. It was containment. Something is imprisoned beyond it. Something that caused The Fracture. Something waiting to return.
