Kedōin Clan

The Kedōin Clan (祁答院一族, Kedōin Ichizoku) is a small clan that has the ability to copy someone's appearance, so well that it cannot be exposed by ninken. However, they cannot copy techniques and other abilities. After a few days, the clan member who used the technique returns back to normal.

They have taken in a couple of students before to teach their Hiden technique, these people having earned their trust. They have not taught their craft since then.
