Ouga's name in kanji literally means "King Teeth", and this young Wild Walf cheetah can be quite viscious! His mother was captured from the wild by humans when she was pregnant with Ouga. She was put in a cage in a zoo, so Ouga was born in the zoo. His mother told him that his father was the strongest type of cheetah in the forest with royal blood (assumed a Wild Half), so that Ouga should never bow down to humans. She soon fell sick, and was taken away, leaving Ouga all alone.

One night, he caught a waft of his beloved mother's smell, and somehow bounded out of the cage to look for her. The image of his dead mother, stuffed, traumatized Ouga for life. From then on, he started to hate all human beings, and swore that he will take revenge, and kill all humans. And he starts with taking Taketo hostage O_o
What he refuses to acknowledge is that a woman-worker at the zoo who takes care of Ouga really cares for the cheetah (she doesn't know that he's a Wild Half), and will change his life.
