Unnamed incarnation

The unnamed incarnation was created by Naraku after Kikyō destroyed Naraku's right arm. Out of all the incarnations Naraku created, this one had the shortest life - only a few moments. It slithered out of one of the pots containing Naraku's flesh and attempted to wrap its tongue around Kikyō's ankle. However, at the very moment that it did, it disintegrated into ash. Kikyō had armed herself with the dirt from Onigumo's cave, which absorbed the bandit's lust for her. This demon served as a preview of what would happen to Naraku himself if he attempted to harm Kikyō.

Physical description
Its body structure was similar to Kagerōmaru's. Given that its brain and ribs were exposed, it was highly possible that this incarnation was not fully completed.
