Dark Release: Under the Knife

Using Chakra stored by the Inhaling Maw, Kaasage makes eye contact with his target locking them within a Genjutsu. A torrent of leaves covers up Kaasage's body giving him a moment to leave the scene so that the Genjutsu is not ruined. Following that a false Kaasage appears, and places his fingers through the head of the opponent. When it seems Kaasage has reached the brain the target watches everything turn pitch black, simulating unconsciousness. A moment later the target will find themselves strapped down onto an operating table while Kaasage operates on their body. The user feels the stimulus of pain from medical procedures without any sort of numbing before hand.
