The Masamune (正宗, Masamune, or マサムネ, Masamune?), also known as Masmune, is a weapon that has appeared in numerous titles in the Final Fantasy series. It is usually one of the most powerful katanas or swords and is often found late in the game.
The Final Fantasy VII Masamune is Sephiroth's signature weapon: an oversized Japanese Nodachi. Said to be the only one able to effectively use it, Sephiroth wields the Masamune across all of his appearances throughout the Compilation of Final Fantasy VII.
