Musashi Miyamoto

A swordsman from the early Edo Period, famous as the strongest swordmaster in Japanese history.
Learned in the “Niten Ichi-ryu” (a school that was supposedly founded by Musashi), an expert of “dual wielding” that employs a long sword and a short sword.
....or so it should have been, but it seems that her circumstances are somehow different from the Musashi that left his name in history.
