Yamanaka Hijutsu: Itaidōshin

Yamanaka Hijutsu: Itaidōshin (山中秘術:異体同心, Yamanaka Clan Secret Technique: A Harmony of Minds in Different Bodies) is a spying technique in which, rather than taking control of the conciousness and body, the user's spirit "rides" along with the target. In this state they are able to full experience anything the subject is experiencing. As with most Yamanaka techniques the user's body is defenseless while using this technique.
