In the sky above the city of Grayvale, two powerful beings representing different worlds collided.
One of them was the Guardian of Light, a 5-rank being from a mid-level world known as the Incomplete World of Light and Darkness. Her opponent was the Light Valkyrie, a 5-rank being from Junonia, a higher-level world.
The two worlds from which these creatures originated were completely different from each other.
The Incomplete World of Light and Darkness was an elemental world dominated by one or more powerful elements.
Junonia, on the other hand, represented a more multifaceted and complex world, where all kinds of elements and other types of energies existed.
The strongest being in the elemental world reached the 6-rank, while in Junonia there was a famous strongest being of the 9-rank.
However, there were also legends and rumors in the Junonia world about a mythical rank above Rank 9.
