Fire Release: Devil's Ash

Fire Release: Devil's Ash is an unique technique of Dan Uchiha that he created from studying his two respective clans hiden and use of Fire Release techniques. Making the hand signs and building fire chakra a pitch black smoke and ashy substance will emerge in abundance from the user's mouth. Apart from the eerie black coloration of the ash it also manifests a develish looking face almost appearing as if the substance was alive.

After the user has conjured the ash the can manipulate it to surround themselves and or their enemies. Apart from serivng as a smokescreen to hide the prescence of the user the ash also blocks all of the 5 senses including sensory abilities of the target. In addition the ash will prevent anyone but the user from leaving as it will solidfy its exterior to trap the target. The user while in the ashy smoke is also able to sense all movement of their enemies that are trapped within. The user can also extend the range of the ash to trap more enemies as well. However, this technique also serves as an assassination technique because the targets within will be forced to inhale the ash which then can be ignited by the user to kill all their enemies by incinerating them from the inside apart from the user themself. They can also cause the ash to disperse in the air rather than form a large amount of ash as a single entity to kill a large amount enemies at once as well. Also Wind Release technique don't seem to work on the ash and individuals outside of the ash are unable see or hear anything going on within the ash.
