And here we move on to Sash's weapon, Muramasa. An Immortal Arm bound to Sash's soul and obeys his every command. It also amplifies his Dark Magic and Immortal Trigger abilities.

Exposition time!!

As a young child, Sash witnessed his mother being raped and murdered whilst hiding in a safe spot by a group of thugs. He vowed to get vengeance on her mother's assailants and trained in the ways of ninjutsu and develop unrivaled speed. However, during his training, he stumbled into a hidden cellar in his old home and discovered a rather large case. When he opened it he discovered Muramasa and once he took it into his paw, the blade's spirit started to communicate with him, saying that it was left by his father, Kleetra, as a memento. Sash at the time was unaware of his Immortal Heritage, but regardless; his soul bonded with the blade's spirit and granted him power and enhancing his already impressive abilities.
