Thousands of years ago, two entities engaged in a battle that shook the entire universe. Unable to secure victory, one of these entities imprisoned the other in seven fragments and scattered them across the far reaches of space.

Five thousand years later, on a remote planet…

With each passing year, one of these fragments gradually weakened, allowing negative energy to flow through a rift. This malevolent corruption slowly spread across the world like a sinister shadow.

However, this malevolence did not affect intelligent beings, sparing them from its poisonous touch. Even the irrational were mere pawns in its hands. Over time, this dark force infiltrated the realm of the inanimate.

Gradually, these fragments acquired power beyond the reach of ordinary humans or any other form of life, mastering it. They were then labeled as demons.

Throughout the centuries, in a world immersed in chaos and despair, humanity contemplated its dark fate. Yet, the fearless emerged, individuals willing to sacrifice themselves to strengthen the fragments and contain the spread of evil.

They were hailed as heroes by the people. Their feats turned into songs that echoed far and wide. Mothers narrated their exploits, and children aspired to be like them.

However, after the departure of the first generation, the next one took on the responsibility of protecting the twelve zodiac seals that kept evil imprisoned. As time advanced, these same saviors came to be seen as malevolent.

Today, cities and towns gather their finest warriors and send them on a single mission across the world:

"Find and annihilate the fearless!"
