It allows the user to put their opponent under an illusion using only words and speech. By infusing chakra into the tongue of the user, any target within auditory range of the user will become easily swayed in a post-hypnotic trance of their will and self-assurance; forcing them to face their innermost trauma as realised by the user's words in an effort to mentally break their spirit. Once told to look behind their back the genjutsu becomes complete, causing them to awaken as an obedient follower of the user.
