The series
Each episode tells one fight from Musashi's life, then shows how much of it the oldest sources support.
Episode 01 · 5 min
Miyamoto Musashi later wrote that he fought more than sixty times and never lost. The first, he said, was against a grown man called Arima Kihei, when he was thirteen. The episode tells that fight as a later account describes it, then shows how much of it the older sources support.
Episode 02 · 7 min
In Kyoto, the Yoshioka sword school meets Musashi in three escalating contests, as told on a stone his adopted son set up in 1654. The episode then lays that account beside the other versions, including the tellings from the Kyoto side.
Episode 03
Two rival teachers agree to settle a quarrel on a small island in the strait between Nagato and Buzen. The episode tells it the way the oldest surviving account does, then looks at who else wrote it down.
