The Cursed Odachi (蠱物の御立ち, Majimono No Odachi) is an extremely powerful, dangerous, legendary weapon of high infamy and ill repute which was used by the dark shogun during the time when he reigned over the world. As his personal weapon, the cursed odachi is considered the only tool that is capable of withstanding his immense strength, imbued and charmed with evil, wicked properties and demonic powers which react to the strength and power of the wielder, a weapon constructed as the ultimate killing tool for the dark shogun.
