Inuzu

The user first performs the several handseals, before extending their shadow to underneath the opponents. Once the shadow is effectively underneath, the user creates a vortex from the extended shadow, causing the opponents to be sucked in. If not the opponent is not quick enough, the shadows consume them, before receding back their normal length, leaving no trace of the opponent's existence.

Jiki was able to later advance this technique with the use of the Dark Arts, allowing him to be able to retain some of the chakra that would be expelled by the vortex's absorption of the people.
