The Genjutsu: Blood Release (幻術・血遁, Genjutsu: Ketton) is a technique of Muketsu's that enhances his already significant prowess within Genjutsu. By making contact with an enemy through one of the plethora of weapons he has available through his manipulation over blood, Muketsu can impart his own blood into an opponent. This leaves a small quantity of chakra within an opponent's body. In doing so, Muketsu is able to subsequently direct his own chakra into an opponent's brain with much more ease as a result of some chakra already being present to accelerate and empower the Genjutsu being cast.
