Ryougi Shiki is the main protagonist of Kara no Kyoukai. She is a girl who possesses the Mystic Eyes of Death Perception, a supernatural ability that allows the user to see the inherent mortality of everything (both living and non-living) in the form of lines. In her case, however, what she sees is the Origin of what she is observing. She assists the Garan no Do agency in handling paranormal cases when combat is required.
