^ But you guys forget that the premise of the show was that "anyone can be a samurai", hence Daigoyou which was a lantern used by the night-police was made into samurai by the act of having the kanji written in his body, and Genta who was a sushi-seller. Heck, Takeru was just a boy who had great Mojikara, and pretty much Mako, Kotoha, and Kaoru are women who wasn't traditionally accepted as a samurai, yet they showed they had the best perception and thinking among the rest (in the case of Mako and Kaoru that is... Sorry Kotoha). Plus, Akira Kurosawa's Seven Samurai shows that Kambei eventually accepts Kikuchiyo who was a son of a farmer as one of his "Seven Samurai".
Everything about Daigoyou is Kikuchiyo you know. Plus Samurai 7 which was an anime-adaptation of Seven Samurai had a talkative android Kikuchiyo which really looks like Daigoyou.
