Daisetsusan no Yuusha Kibaou - Episode 1

The conflicting fates of human beings and wild animals are depicted in a naturalistic setting. The main character of the story is Fang, who was born to a hunting dog and a circus-runaway European wolf. Although Fang was raised by a human family, he is a wild animal after all, and is destined to live amongst nature. The story reaches its climax when Fang returns from the circus and faces his foe, a giant brown bear which killed his family. (Source: AnimeNfo)
