Those who possess others by driving out the soul from a body and making it theirs.
Unlike normal spirits, kanshousha cannot exchange bodies at will; they can only switch to another host body when their current body dies. Because kanshousha become the owners of their bodies, choubuku does not work on them. It is, however, still possible to exorcise kanshousha when they are in spirit-form (i.e. between possessions).
