A teenaged 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 and a single point (which is the "origin" of the object) which is shown by having a rainbow-like color in her pupils. A cut along any line will bifurcate the object, no matter the sharpness of cutting tool used, and a stab at the point destroys the object's origin, causing instant death. She recently recovered from a two-year coma caused by a traffic accident. Prior to the traffic accident, she originally had two personalities, a male personality named SHIKI (織 Shiki), and the original female personality Shiki (式 Shiki). Children born into the Ryōgi family are generally male and are raised with two personalities, so the male personality is customarily called the "yang" personality, while the female is called the "yin" personality. It is easy to tell which Shiki is speaking at a given time because they both have a distinct style of speaking, most notably that the female Shiki refers to herself with the pronoun watashi (私), while male SHIKI refers to himself as ore (オレ). After waking from her coma, Shiki discovers that she can no longer feel the male Shiki's presence and assumes that he died because of the accident. She also feels a detachment from her memories before the accident, and while she knows she is Shiki, she does not feel that she is. In the hopes of regaining herself and the "dead" Shiki, she puts on a cold façade that somewhat resembles the female Shiki's and tries to act as the male SHIKI did. Tōko understands the sense of detachment Shiki feels, but considers the current Shiki a third, new personality. She assists the Garan no Dō agency in handling paranormal cases when combat is required.
