Kedōin Clan

This small clan has a secret technique called face copying jutsu, that allows them to copy's someones appearance. Although it can't copy jutsus and skills and the user needs to be close to the person beeing copied, it can't be exposed by nin-dogs, and after a few days the clan member who used the technique returns to normal.

The clan were first introduced in the filler arc when Kiba, Hinata and Naruto goes on a treasure hunt mission.
