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.
