The user links his conciousness to many spectral replicas to create a type of "spiritual network" which he uses to gather information about the goings on within the shinobi world. The spirits are incorporeal and can not readily be sensed or felt. He can also use this ability as a form of astral projection; the user projects his own spirit which looks exactly like him, is impervious to physical attack, can summon ghost replicas, change size, fly, and is intangible.
