Demonic Illusion: Heavenly Fog

A that creates a large volume of a smoke like fog which encompasses a ten meter area with the user at its center, the area becomes a black spot to sensors outside the area and to sensors inside who attempt to sense it creates a kaleidoscope effect due to the yin chakra being spread through out the area. The user is able to manipulate the five senses of those trapped inside the technique to a varying degree which depends on the number of targets as well as the users mastery of the technique, because the technique is created using the users body as a catalyst for producing the fog it is impossible to break the illusion unless they find a way to disrupt the users internal chakra flow. The only known downside to the technique is that every change in the targets senses costs the same amount of chakra as reactivating the technique.

Ruka Yamanaka
Ruka being the creator of the technique boasts the highest degree of mastery with the technique, this allows her to place up to five targets under the total hypnosis created by the fog, though her true mastery of the technique can fool even the strongest of dōjutsu if there is a single target in the fog. Using the technique as a trump card, she can completely disrupt her targets senses and manipulate them in different ways, normally creating apparitions of herself to catch the opponent off guard after they have attacked it, though potentially she can alter all five of their senses in anyway she pleases.
