Kiba (キバ(牙) ?, lit. "Fang") is a white wolf who follows his instincts towards Paradise. When he was young, his pack and family were slaughtered when the forest where he lived was burned to the ground by Jaguara's troops. He was then raised by a shaman who told him that he had a purpose, explaining why the forest had sheltered him from the flames. The shaman told him that he would have a great journey ahead of him, and that journey was to find Paradise. Kiba begins his quest for Paradise in the hope that there he will find "a future". It is revealed later in the series that he is in fact the chosen one who is destined to find and open Paradise. Kiba tends to be impulsive and thinks with his heart rather than his head. He tends to be distrustful toward humans, and in the early episodes his pride as a wolf makes him reluctant to disguise himself as a human, but that changes when he meets Hige, who tells him that his pride won't count for much when he's dead. He's also utterly devoted to Cheza and constantly risks his life to protect her and steal her back from the nobles. After Earth's regeneration, Kiba is seen at a city in his human form.
Voiced by: Mamoru Miyano (Japanese), Johnny Yong Bosch (English)
His voice actor Mamoru Miyano felt Kiba was a "wolf of few words" and that his quiet nature made it hard to know what he might be thinking. Though Kiba is rarely bothered by events, Miyano did not think this was an indication that he was strong, rather he felt Kiba was attempting to hide his insecurities. In depicting the character, Miyano found it most difficult to voice the initial scene of the first episode, in which Kiba lies dying and in voice over saying there is no Paradise and that there is nothing at the end. He was so nervous about shooting the first scene, he had trouble getting the lines and voicing correct, eventually freezing up completely before he was able to calm down and complete the scene.
