Divine Radiance: Murakumo

The Divine Radiance: Murakumo (神輝・ムラクモ) is an Arch-Enemy Event Weapon created after the Great Dark War. It takes the form of a massive sword while on standby, but once activated, it turns into 8 floating blades surrounding the user, and their armor.

Information
The Divine Radiance was created by Nine and Relius Clover. after the Great Dark War, and because of this fact it doesn’t have a part of Takemikazuchi’s core – instead, it uses a Prime Field refined in a Kiln.

This Event Weapon was designed to counteract the Sankishin, and the Amaterasu Unit cannot affect it, making it the only one that is not affected by causality.

A Prime Field equipped with the Divine Radiance: Murakumo is called a Murakumo Unit, and at the same time, it is an Anti-Sankishin Core Unit – the only known are Lambda-11, Mu-12, and Nu-13.

Murakumo is made of Hihiirokane, a tough and light metal, and it can connect to the Boundary, drawing out unlimited amounts of energy from it.

Lambda, after being reconstructed by Kokonoe Mercury, uses an imitation of Murakumo made of titanium and light metals. At the beginning, she was unable to equip this weapon at will, and the use of special machines in Kokonoe’s laboratory to put on the armor and take off was necessary. Eventually, she can summon her armor like the rest of the Murakumo Units.

As the Sealed Armament: Izayoi acted as a prototype for the Murakumo Unit, by extension it can also be considered a prototype of the Murakumo.
