I couldn't stop laughing at Naoshi Kamikazing his way into the battle, explaining the Shinsengumi to Hijikata despite no one asking him to and then flying a dragon. This, along with him telling a dragon to fight him when he first arrived, fighting Africanus on first meeting him and becoming the God of a bunch of animals who don't speak his language, he's confirmed for best character in Drifters.
Or at least, joint best with Hannibal.
