Himura Kenshin
Himura Kenshin (pronounced Hee-moooooooooo-rah Ken-sheeeen) is a samurai-ninja type person who has figured out how to use his/her (delete as appropriate) ninja skills for good, rather than evil. Well, originally evil, but now good. Instead of saying "I", Himura uses the phrase "this one", causing some readers to believe that Himura hates the letter I, which is kinda stupid because there are 2 I's in "Himura Kenshin".
Himura was originally known as the Hitokiri Battosai, but then decided to change it because it's hard to say. Himura is 28 years old, with the face of a 10 year old most of the time and the face of a 46 year old whilst in battle-face-mode. Himura says oro rather than traditional exclamations of surprise like oh my good golly gosh. Himura is so bad-ass that he carries a sword around all the time, even though there's a sword ban. Bad ass mother fucker.
Himura is also ginger. Back to the subject of gender ambiguity; on average, Rurouni Kenshin readers will read to at least the end of the first book without realising that Himura is actually a boy. Wait… Himura is a boy? Eww.
Aside from all this, Himura is still awesome. So awesome, in fact, that he can get away with having a ginger ponytail and wearing pink robes and people still assume he's straight because of the girl who follows him round. She also hits him often, because she's jealous of his mad ponytail.
