Question

Why does Vivi call Zoro "Mr. Bushido" from the anime One Piece? ?

Answer 1

well if you look up the word bushido ( http://en.wikipedia.org/wiki/Bushido ) its basically the way of samurai....and zoro very much follows the way of a samurai so Im guessing vivi calls him that since since zoro follows the moral code of samurai ^_^
