Was Miyamoto Musashi Really That Good?

I grew up playing the Onimusha series just because it felt cool. Years later, Onimusha: Way of the Sword made me look at Miyamoto Musashi and wonder: how much of the legend was actually true? The undefeated duels. The Yoshioka clan. Ganryu Island. The wooden sword. Sasaki Kojiro. Some of it comes from historical records. Some of it gets much harder to verify. So this time, I wanted to look at the real Musashi behind the games—and see where history ends and legend begins.
