Mind's Eye of the Kagura

This ability allows Karin to find, sense, and track individuals through their chakra over vast range that exceeds ten kilometres.[2][3] This is done by focusing and opening the mind's eye, though Karin has it active often. The ability extends to telling when a person is lying from the fluctuations in a person's chakra made from dishonest emotions or detecting if someone, including herself, is under a genjutsu. Also by focusing on a particular chakra Karin can perceive its location and movement with great detail.
