Lux Sanctus: Murakumo

The Lux Sanctus: Murakumo are a pair of Nox Nyctores that are classified as the tenth of their series. In in a default form, a Murakumo is the size of a large broadsword with various ornaments on its hilt. Upon activating, it takes the form of armour with eight floating blades by its sides.

Information
One of the two Nox Nyctores to be made after the Dark War, the Lux Sanctus: Murakumo were designed by Nine the Phantom and Relius Clover. Its prototype was the Sealed Weapon Izayoi as they are designed as "Anti-Sankishin Core Units" with the purpose of being able to kill a Sankishin - to this end, Murakumo is immune to Phenomenon Intervention, being its unique trait as a Nox. There is very little information on this Nox and what it can exactly do.

Murakumo is the only Nox of which two variants exist, both being constructed of the mythical alloy hihiirokane. One was owned by Nu-13 and another by Mu-12. Neither have been seen in the new world created by Ragna the Bloodedge. Lambda-11 owns an imitation Murakumo that was created by Kokonoe and is made of titanium and other light metals

Wielders

 * Mu-12/Noel Vermillion - was perfected into a Kusanagi; presumed that she still owns it.
 * Nu-13 - her Murakumo's status and location is unknown.
 * Lambda-11 - wields an imitation of Murakumo.

Lux Sanctus: Murakumo
''Nox Nyctores number 10. Possessed by Nu.''

''It takes the form of a massive sword while on standby, but once activated, it turns into 8 blades surrounding the user. As the owner of this weapon, Nu is called a 'Murakumo Unit.'''

Etymology
In Latin, "Lux" means "Light", while "Sanctus" means "Holy". "Murakumo" comes from "Ame-no-Murakumo-no-Tsurugi" which is the original name of "Kusanagi-no-Tsurugi". Literally, "Murakumo" means "Gathering Clouds", so a literal translation for the localized name of Lux Sanctus: Murakumo could be "Holy Light: Gathering Clouds".
