With me enjoying this and 7 Ronin lately, I decided to rewatch one of my favorite movies, Shichinin no Samurai.
As I was watching, I realized that all of the characters from this game correspond to one of the titular 7 Samurai. I thought it was really cool, and the art captures the samurai pretty well (though they did decide to go with Kambei before he shaved his head). Then I was thinking, wait. Which one is Daisuke. Then I realized one of the Samurai is named after the actor Daisuke Kato, instead of the character he played (Shichirōji).
Well, besides for Shichirōji, all of the characters have corresponding characters in Samurai Spirit. Well I guess Shichirōji does too.
