Divine Radiance: Murakumo (神輝・ムラクモ Shinki: Murakumo, localized as Lux Sanctus: Murakumo) 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.


The creators of Murakumo are Nine and Relius Clover. Unlike the other Event Weapons, it was created without the part of Takemikazuchi’s, which is replaced with a Prime Field’s smelted in the Kiln. Each wielder of this weapon is called a Murakumo Unit – the only known are Lambda-11, Mu-12, and Nu-13.

Originally, a Murakumo Unit was intended as a Weaving Zero Armament, a part of a special type of a Dimensional Boundary Contact Prime Field, the Kusanagi. Similar to its prototype, it was meant to weave with the Prime Field and empower it.

Murakumo is made from Hihiirokane, a tough and light metal, and it can connect to the Boundary, drawing out unlimited amounts of energy from it. 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.[1] Later on, it was used in creating another special type of a Prime Field, that was a lesser form of the Kusanagi, the Murakumo. It was recognized as the 10th Event Weapon, Divine Radiance: Murakumo.

Lambda-11, after being reconstructed by Kokonoe Mercury, used an imitation of Murakumo made of titanium and light metals. She was unable to unequip this weapon at will, and had to put on the armor and take it off using special machines in Kokonoe’s laboratory. After being reborn in the Embryo, Lambda 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.



  • “Murakumo” (叢雲) means “Gathered Clouds”. It is derived from “Ama no Murakumo no Tsurugi (天叢雲剣), “the Sword of the Gathered Clouds of Heaven”. Ama no Murakumo is the original name for “Kusanagi no Tsurugi” (草薙剣).
  • The glossary states that only Nu-13 is the wielder of Divine Radiance: Murakumo.[2]
