葛の葉

Yuuki's partner, a fox-type guardian. This guardian is inherited every generation by the Ootori family.

Unlike the other guardians that commonly have a attribute  such as fire, water or wind, Kuzunoha is a rare kind that has no attribute. Kuzunoha's skill is to enhance the physical abilities of it's partner but Kazunoha herself has no fighting power, so her master needs to fight alone while using her abilities. Kuzunoha can also change it's shape to the image her master is thinking, and this ability has no apparent limitations.
