Slaying Demon: Ōkami

Slaying Demon: Ōkami (斬魔・鳴神) is an Arch-Enemy Event Weapon with the shape of a nodachi. It is wielded by Izayoi, and previously by Hakumen.

Ōkami is made of metal that nullifies the Magic Formulas. Hakumen is also able to use Ōkami to directly slash dimensions, allowing him to view other parallel timelines or dimensions. However, it is unclear if this is an ability of Ōkami itself or a display of the Susanoo Unit’s ability to slash time.

Trivia

 * In BlazBlue: Alter Memory the sword can phase through its sheath, allowing Hakumen to easily draw it for battle.
