Mucro Somnio: Musashi

The Mucro Somnio: Musashi (夢刀・六三四 Mujin Musashi) is the fifth Nox Nyctores and is comprised of two short swords that can join together at the handle. Jubei has been its only wielder.

Information
Made by Nine the Phantom during the Dark War to combat the Black Beast, Musashi was specially designed with Jubei in mind. It was used against the Black Beast during the final battle of the war, having been used to decapitate two of its many heads. After the Dark War ended, the Nox had its core removed by Nine herself, and remained in Jubei's possession.

The blades can cut through anything, even things that cannot be cut - one example would be magnetic fields or even sorcery. Musashi's powers are not just limited to cutting space, but also shifting it, as the entrance to the First District had the space around its entrance shifted so it was impenetrable without a special key. There are some things that Musashi cannot cut through, namely the chains of the Geminus Anguium: Ouroboros.

When not being used, both swords are stored in one sheath, both on either end. Jubei wields the swords with his paws, tails, and mouth. Physically, the swords have white handles and brown pommels, with large tan guards near the hilt. The blades themselves are short and slightly curved. The sheath for both blades is a bright red and is held onto Jubei with a brown strap.

Mucro Somnio: Musashi

''Nox Nyctores number 5. Possessed by Jubei.''

This weapon was specially designed for Jubei, and can cut straight through things that can't normally be cut.

Etymology
Mucro means "a sharp point" in Latin, while Somnio means "dream". Musashi is likely in reference to the historical samurai Miyamoto Musashi whose martial prowess was legendary. Literally, Mucro Somnio: Musashi can be translated as "Sharp Point of Dreams: Musashi."

The Japanese name is 夢刀・六三四 mutō musashi. 夢 yume means dream, and 刀 katana is a one-edged blade. 六三四 musashi is literally "six three four" in succession, and in this case is used as a name, solely for phonetics.

Trivia

 * Musashi is the only Nox Nyctores created during the Dark War that has never exchanged hands, having always remained in Jubei's possession.
