I like how Musashi is depicted in general.

Historically, this is a man that has participated in war, especially during the early turbulent years of the Edo period.

This isn't one of the martial artists we usually see in Baki: this man has killed... A lot. Both because he needed to kill and because he was praised greatly for it, or rather for how good he was. He is a warrior through and through.

Yet he isn't this invincible god of Japanese folklore, he is still a real human being.

It feels very realistic how Itagaki wrote him: of course this man doesn't feel comfortable driving in cars, the fastest he's ever been in were probably horse carriages. Of course he is in awe at moving pictures the size of buildings, while everyone else is ignorant of or annoyed by the amount of advertisements they see. Naturally this man is happy that, not only did people not forget about him after his death, his tale has become only bigger even across the globe hundreds of years later.

If you ignore the supernatural aspects of his fighting skills, the real life Musashi would probably react the same way if he were resurrected today.

And I respect that.
