Face Copying Technique

The user looks at a target to copy their appearance. A flawless Transformation Technique, the copied person's allies would not tell the difference and ninken would not smell a different scent. Though the user copies the person's face and body, they can't use their techniques or unique abilities and they are also very weak to attack. In order to copy an appearance, the user needs to wear a special mask and stay close to the target for a long time. When the technique starts, the user's eyes start to glow. This technique is unique to the Kedōin clan.

The transformation lasts for only a few days though a rare few have learned to truly master this technique to the point that they can retain their disguises for weeks, given that they are able to re-copy the person again.
