Muramasa was a legendary[citation needed] Demon blacksmith in Japan.[1]

16th century

During Japan's century of civil war, starting by mid-15th century, Muramasa forged the Black Blade using a portion of his own dark soul. The Blade caused its possessors to be overcome with unquenchable bloodlust.[1]

20th century

In the middle of the 20th century, he was sought out by Logan after his wife, Itsu, and he believed her unborn child as well, were killed in Jasmine Falls. Muramasa agreed to make Logan a sword, forged out of his incredible depths of rage and hatred. The process took many years, but the blade was prepared for Logan when he returned to Muramasa's camp after regaining his full memories after M-Day.[2]

Another Muramasa blade caused trouble for Logan in-between these two dates. The Blade of Muramasa wound up in Madripoor while Logan was playing Patch. The evil in the blade corrupted and possessed anyone who wielded it, until the Silver Samurai proved to be a worthy master for the sword, and claimed it as his own.[3]


  • Muramasa can forge portions of the spirit and emotions into powerful swords.[citation needed]
  • He was allegedly immortal, and is served by armored samurai-like warriors.
