Black anime characters

I've personally never seen a black anime character.  Do they exist?

bleach one of the gotei 13 captains is black

in dragonball, one random ass episode, goku goes to the door and askes a black woman for something (i forgot). But i indicated to my friends that omg it was a black person on anime, but they just didnt see how rare it is. Anyway she was dressed up... uhh with a dress and her hair wrapped with something on it, resembling a slave.... no offence intended

Yoruchi is pretty hot and being sisters with that other guy, the shopkeeper, is she by blood or by other means his sister?
