A relatively simple technique developed by Engetsu Uchiha in which the user exerts their control over an animal followed by using the Sharingan that manifests within the eye of the animal as a conduit to "relay" various Genjutsu or Dojutsu, the most common of which being simple hypnotism. This technique consumes very little chakra, an amount so negligible it can be said to be non-existent, when the user has already mastered both of this technique's Parent Jutsu and is mainly used to deliver a Genjutsu from a highly unexpected source or to use an opponent's Summon against them.
