Murakumogiri

Slotted into the twelve Supreme Grade Blades, Murakumogiri counts among the most formidable weapons ever made. Whitebeard kept it at his side for a span exceeding forty-six years, right up to his death at Marineford. The weapon's title draws on a legendary Japanese sword, the blade first called Ame-no-Murakumo-no-Tsurugi and later famous as Kusanagi-no-Tsurugi.

Sized to suit its towering owner, this is a huge Tomoe-pattern naginata whose shaft carries red and yellow banding and finishes in a rounded pommel. A brass collar engraved with a sea serpent fastens the wide, sweeping blade to the pole, and langets extend from that collar onto the edge. Wielded by Whitebeard, it crossed with the twin blades of Oden, namely Enma paired with Ame no Habakiri, plus the Supreme Grade sword Ace that Roger carried, and Shanks' Gryphon as well. Feeding either his Gura Gura no Mi or his Armament Haki into the weapon multiplied its destructive reach enormously, and the latter also cancelled out whatever Devil Fruit protection a rival might depend on. Its resilience bordered on absurd: Akainu's magma failed to melt it, and it took a two-handed downward blow from the giant John Giant without harm. Even two years past its owner's death, the naginata stood on his grave, untouched by weather. That toughness is what let Newgate route his complete strength through it. His signature Naginata Rasetsu enclosed the blade in a bubble of quaking force to greatly stretch its range and power.

Only Edward Newgate ever carried Murakumogiri, first shown holding it some forty-eight years before he died. He most often fought with the weapon in his right hand, at times managing it one-handed, and would occasionally drive its blade into the ground so that both hands were free to unleash his Devil Fruit. When Marineford's Summit War claimed his life, the naginata was mounted upon his New World gravesite, planted there with his Jolly Roger and coat left hanging from it. His history with the weapon reaches back into the Rocks Pirates era, and Shueisha's VJump Play even had a cardboard replica of it built.
