A tundra wolf kept at the zoo, which is one of the animals cared for by Mishio. Has a lone-wolf personality, and thus he doesn't listen to the zoo caretakers. However, he trusts Mishio who doesn't try to be playful with him, and follows her orders to a certain extent. After the zoo director succesfully lead Mishio into a trap, he gently comforted her, which changed their relationship of trust to that of deep affection. [Translated from Official Site]
