Signati Gladio Crystalis: Murakumo

Signati Gladio Crystalis: Murakumo is a Legacy Weapon that has been wielded by Es and Touya Kagari.

Information
The Signati Gladio Crystalis: Murakumo is an incredibly large katana-like sword that is more than five feet long. It is incredibly sharp, able to cut through a Union’s crystal with ease. Murakumo can be summoned to the wielder’s hands from out of nowhere. Where it goes when not in use is unknown.

Unlike other Legacy Weapons, Murakumo doesn’t seem to have any cost for using it. However, Murakumo is sentient and chooses its wielders. It is said that nothing can make it move if it finds someone untrustworthy.

Signati Gladio Crystalis: Murakumo was first wielded by Es as part of Sleipnir in XBlaze Code: Embryo. In the climax of the Es Route Touya takes up Murakumo to battle Sechs and continues to wield it after Es erases herself from the world. When Es returns in XBlaze Lost: Memories she takes up Murakumo again to battle Freaks. She remains its wielder, with Touya using his Drive to make a replica of it from from his own blood.

In BlazBlue: Central Fiction Es is still wielding Murakumo. However, it now is covered in a large sheathe. This sheathe absorbs and stores seithr within it. When Es uses her Astral Heat, she removes the sheathe, revealing the original sword inside it.
