Arch-Enemy Event Weapon

The Nox Nyctores are a set of ten weapons.

Information
The first nine were created during the First War of Magic based on the Sankishin, to combat the Black Beast. Only those with the highest proficiency in the Proper Use of Ars Magus can wield them, and even then, there is a significant risk of mental burden on the user. It's said that the Nox choose their masters. One of the primary functions of Nox Nyctores is to unburden their owners of "needless" emotions and enhance others; this has a profound effect, for example eliminating fear, but owners may also find themselves losing their compassion, remorse, etc..

Among the Nox Nyctores, the Murakumo Unit is unique in that it was produced after the Dark War, and is actually an Anti-Sankishin Core Unit, created in a Cauldron as a means to make contact with the Boundary, where its soul exists. During the Ikaruga Federation's 12th attempt to produce one, together with a Sector Seven research team, the experiment was interrupted by an attack from Take-Mikazuchi and that resulted in the creation of Noel, in an incomplete state. Afterwards, three base bodies were stolen from the NOL and Nu was created in Kagutsuchi. Ragna's already destroyed the two others.
