Kouga Civilization

Kouga Civilization (黄河文明, Kōga Bunmei), also known as The Yellow River in the English Anime.

History
is the human leader of the trio. This one fights with a sword as well, but has various ninjitsu abilities such as a freezing sweat ability and... curling? (it should be noted that the symbol on his outfit bears a close resemblance to the Tidus/Jecht symbol featured throughout the game Final Fantasy X). Interestingly in one episode he removes his top to reveal a female body underneath (although this could just be the majide metamorphosis).
