Prologue
During ancient civilization, human beings had desires. These desires would awaken demon beasts from the underworld. They were called Acherons. Taking advantage of these desires they possessed humans with evil desires and killed humans. Mankind was dwindling because of these demon beasts. A council was then established to fight against these beasts. They developed weapons to fight against them. These weapons would be used by skilled warriors to destroy the Acherons. In time these demon beast hunters would be known as Aether Knights. To this day they fight to protect the human race from Acherons from the dark.
In the ranks of the Aether Knight, there is one title that everyone knows: Silver Knight Gashado. The strongest knight in their ranks he is assigned to cases where other knights cannot handle.
