This was a technique created by Rinne Higaki in an effort to create a blade for the Seitō Hakari and served as the basis for the Shutōryū. User tightens together his fingers and forms a "knife hand" hand gesture with one of his hands. His energy is focused along the back edge of his knife hand and, like that of a sword, user slashes his hand across in a particular direction and manner of his desire. The action of this motion causes anything and everything within the narrow range of his knife hand's back edge to be cut down. Sen'eikate has a very controlled aim and direction of destruction. It is so precise that most opponents are unaware the strike had occurred until the injury forms on their body or the target in question has already tore in two.
