Taro is a small stuffed animal that Kyou carries with her. He is, just like Frivelen, able to transform into a huge wolf-like beast to fight his opponents.

His full name is Cerberus Grendy and he comes from the Zoi Wolf Fang Clan. He cares about Kyou a lot and is very disgruntled and worried when she goes missing on one of their folklore hunting missions. He is also easily touched and cries upon hearing sad stories but as an opponent, he is very strong and capable. He and Frivelen share mutual rivalry and often clash and pick on each other.
