Extremely over-powered super natural ability that allows the user to kill anything in excistance by percieving the targets point/lines of death. These lines/points can be seen on the object/person the user is trying to kill. This ability is limited to what the user can percieve, as such the user cannot kill things or entities that can a: not be killed or b: cannot be percieved. If it has an end, it can be ended. There are so far only two users of this ability in the type-moon universe: Shiki Tohno and Shiki Ryouga.
