Sword of Izanami (weapon)

The Sword of Izanami (イザナミの剣) is the true Murakumo Unit.

According to Nine the Phantom, the Divine Radiance: Murakumo is incomplete, and she advised Nu-13 to collect all of the Arch-Enemy Event Weapons and defeat Izanami to get the real Murakumo Unit. When it’s done, Nine convinces her that her dream to fuse with Ragna might come true.
