A youngster who may have all the skills and attitude to be a samurai, but has not yet actually faced true battle. Often theKid Samurai has practiced an "art" form like kendo, instead of a battle form like kenjutsu, and has yet even to draw blood in a fight. Sometimes played as an arrogant buffoon, other times as a "little brother" sidekick. If he doesn't die a tragic death inone of his first true battles, theKid Samurai may mature into the trueSamurai.
Sometimes they'll use aNerf Arm. Sometimes they'll be aKendo Team Captain in their spare time.
