Kouga Civilization  

Kouga Bunmei, The Yellow River, 黄河文明

The leader of the trio is a human. He wields a sword and possesses abilities such as freezing sweat and curling, which are associated with ninjitsu. His outfit has a symbol that resembles the one found in Final Fantasy X's Tidus/Jecht character. In an episode, he transforms into a female body by removing his top, although this could also be due to a majide metamorphosis.
