Miyamoto Musashi is the protagonist of Onimusha: Way of the Sword. The official PlayStation description calls him a fierce young samurai who arrives in Kyoto seeking to prove that he is unmatched in the way of the sword.
Musashi's role
His arrival in Kyoto does not lead to an ordinary duel or a simple test of skill. The city is surrounded by Malice, and Genma have entered the world of the living. Musashi becomes part of a dark-fantasy story where swordplay and the supernatural are inseparable.
The face of the protagonist
CAPCOM says Musashi's face model is the late Japanese samurai-film star Toshiro Mifune. The official description presents this as a deliberate connection between the character and the image of the striking samurai.
