|Translation:||JP Dream Swords: Six Three Fourths|
LA Dream Blades: Six Three Fourths
Mucro Somnio: Musashi is a Nox Nyctores with the shape of a pair of kodachis, one stored in each end of the sheath.
Supposedly, Musashi's power is to cut "what cannot normally be cut"; it is unclear on what this meant. It is heavily implied that it is able to destroy a magical field or barrier, or possibly anything it chooses to cut.
- It is apparently named after Musashi Miyamoto, a historical samurai who was known to fight using two swords.
