Following his failure to acquire the fabled Sword of Kusanagi during a past mission, Shigeo Uchiha sought a fitting replacement that better matched his own abilities and talents, unfortunately, such a sword did not yet exist so together with the finest swordsmith in Kumogakure Shigeo set out to have the weapon made; since he understood that no mere masterwork blade would suit him he used his own significant abilities to enchant the edge in various ways.

The first way was done during its creation for no ordinary fire would do. So the blade was painstakingly forged in the eldritch flames of Shiranui over a period that took several days. Being a specialized Chakra Blade of the highest calibre even then the blade took readily to the Yin-flames of Shigeo's magnum opus. Its cut produces a short-lived Genjutsu of a similar nature as they do, but only for an instant making its touch wound both the mind and spirit of his foe simultaneously.

When the blade was adequately acclimated and compatible with the forces of Yin that helped forge it, Shigeo began the next phase of its creation and cast Tsukuyomi upon it and maintained that effect for multiple decades. Within the World of Darkness, the Uchiha scion connected Yin to Yin and significantly increased its power by *burnishing it in oblivion* as Shigeo put it. Yet this alone would merely produce a blade with limited abilities. Still, he had a tool that no one else did, and that was the essence of the deceased Muramasa, a horrible war criminal of Kumogakure who had been stolen away by Omoikane rather than face the consequences of his crimes.

Utilizing the ability of his Mangekyo in tandem with masterful Fuinjutsu experts he and Shigeo's companions succeeded in separating Muramasa's essence from Omoikane. They bound him to the sword itself, the idea being that his lingering chakra and mental energies would serve to ground the weapon in reality and maintain the powerful effects upon it while simultaneously allowing Shigeo the ability to access multiple disciplines of Omoikane without cost. Unfortunately, however, this worked out much too well for anyone's liking as not only was the experiment a success but the sheer amount of preparations produced a freak accident. It turned Muramasa sentient and allowed him to interact with his bearer telepathically and thereby permitted him to influence him in subtle and direct ways by befouling Shigeo's mood, making his thoughts darker and even allowed for communication between the two.

Muramasa's essence is possessing overwhelming bloodthirst; however and once drawn it outright refuses to be sheathed until it has drawn blood. If this requirement is not met to its liking, it will turn on Shigeo instead to taste his. This is an essential process to maintaining its might for the essence is composed entirely of mental energies. So it craves physical energy which it drains from the blood of those it harms to reinforce and continually empower and recharge its extraordinary properties. Effectively, it utilizes the physical energy present in the blood to create its own separate reserves of Chakra which it then employs as it sees fit.

Forged as it is through the aid of Tsukuyomi's dreaded World of Darkness the blade has the unique ability to turn that world inside out along the path of its stroke. Manifesting as monochrome blotches of dead colour that linger briefly before dispersing and possess unusual properties which form and shape the world around them in small but overt ways. Providing Shigeo with a direct tool with which to channel these strange powers, and thereby allows him to some extent create form and shapes out of nothing but ideas by manipulating the quasi-illusory landscape. This power works by forming a direct connection with Shigeo's left eye, and consequently, this may only be used if Shigeo Uchiha's Mangekyo Sharingan is presently active. Beyond that, the relationship is strong enough to render the blade as sharp as a nightmare according to the spirit that dwells within it, with it even growing sharper as Shigeo's skills within his main field grow.
