|Mucro Somnio: Musashi|
|Debut||BlazBlue: Calamity Trigger|
It is apparently named after Musashi Miyamoto, a historical samurai who was known to fight using two swords. Supposedly, its power is to cut "what cannot normally be cut"; it is unclear on what this meant.
In Continuum Shift, it is heavily implied that it is able to destroy a magical field or barrier, or possibly anything it chooses to cut.
