Adamanto

Perseus, son of Zeus, beheads the Gorgon Medusa with the legendary blade, Harpe. Constructed of Adamant, the weapon is considered indestructible. When Lord Kami, Shinto God of Iron, discovers Harpe is the last source of the precious ore, he charges his fiercest warriors to steal the weapon. Lord Kami’s subjects are successful, and their master proceeds to fuse Harpe with a corrupted form of Blood Magic to forge a weapon the likes of which man or God has never suffered — the nexus of Adamanto!
