The Chakra Hound Technique (チャクラ猟犬技, "Chakura Ryouken no Waza") is a rare Jutsu developed by Tatsuya during his time as an ANBU, with the assistance of several supervisers and other ANBU members. Chakra Hounds can separately take on properties from the Fire, Earth, and Wind elements - being a Hiden Jutsu only those currently in the ANBU are taught its usage; and to teach it to someone outside of ANBU, even if they had been ANBU themselves at an earlier point is concidered a crime unless the instructor has acclaimed specific clearance on the matter from one of his superiours, usually the current Hokage or the current Head of the unit.
