The Murasama started out as a phasular sword called the Muramasa. The Muramasa was created by a legendary Inkla member called Calamità . He had forged the weapon using phasular energy and proper materials. After many generations of using the Muramasa, one battle with a 6'6 mechanical being the handle was crushed and the energy core was destroyed. 20 years of shame later a warrior with the name of Pre-Inkla had found the creator's bladesmith, he convinced him to make the Murasama and he had called the sword Murasama. Pre-Inkla had brought justice back to the Inkla clan.
