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, ect...

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.

No. 05
Owned by Jubei. Its form is a pair of kodachis, one stored in each end of the sheath. It's apparently named after Musashi from the kendo manga/anime series "Musashi no Ken", although judging from the fact that it's a pair of kodachis, it's likely that it is also named after Musashi Miyamoto, a historical samurai known to fight using two swords in hand.

While what it is has not been determined, It is possible that it is the inactive Nox belonging to Bang Shishigami, and may relate to his armgaurds, this is due to the name meaning 'Pheonix Wing', and his gauntlets producing fire on impact with strikes as well as his attack 'Heavenly Pheonix'.
 * Houyoku: ???
