Dream Blades: Musashi

Mucro Somnio: Musashi has the shape of a pair of kodachi, one stored in each end of the sheath. It's apparently named after Musashi Miyamoto, a historical samurai known to fight using two swords. Supposedly its power is to cut 'what cannot normally be cut'; what this means is unclear. In Continuum Shift it's heavily implied that it is able to destroy a magical field or barrier, or possibly anything it chooses to cut.
