The Mind's Eye of the Kagura is a technique, unique to Karin, that allows her to sense chakra with exceptional detail.
By focusing and opening the mind's eye, Karin is able to find and track an individual's chakra over a vast distance that exceeds ten kilometres. By further focusing her chakra, she can extend this range to far greater distances. This ability also gives her the capability to perceive fluctuations in a person's chakra made when a person is lying or if someone, including herself, is under a genjutsu. Also, by focusing on a particular chakra, she can perceive her targert's movements and surrounding area with great detail. These sensory capabilities bless Karin with abilities that even surpass dōjutsu with comparable powers.
The name comes from the word Kagura (神楽, divine entertainment), which is a type of Japanese theatrical dance, considered by some to have been developed by the goddess Ame-no-Uzume. Its roots lie in certain kinds of divination and pacification of the spirits.
Karin uses this technique as her ultimate jutsu in Naruto Shippūden: Ultimate Ninja Heroes 3, in which she throws a smoke bomb that engulfs both her and her opponent in a pitch-black cloud where neither one of them can see. She then locates her opponent with this technique and throws a kunai with a string of explosive tags attached to it, defeating her opponent in the explosion. When Karin uses this on Sasuke, her demeanour changes and after the explosion she swoons over him.
Karin can use this technique in Naruto Shippūden: Kizuna Drive. When used, this technique allows Karin to automatically "dodge" any weak attack for a limited period.
