A teenage girl who recently recovered from a two-year coma. She originally had three personalities, a male personality named and the original female personality , both are aware and conscious of one another, but possessing different qualities. A third genderless personality known as "Void" never manifests due to extreme apathy but also embodies the Root of all existence. As a family of demon hunters, children born into the Ryougi family are generally male. They 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 personality is speaking at a given time because they both have a distinct style of speaking, most notably that the female personality refers to herself with the pronoun . In contrast, the male personality refers to himself as . Upon meeting Mikiya, she gradually finds happiness through their relationship, and a schism develops between her two personalities. When she awakens, she finds herself unable to connect her memories to her current identity. 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 male Shiki's and tries to act as the male SHIKI did. Touko understands the sense of detachment Shiki feels but considers the current Shiki a third, new personality. Her near-death experience awakened her "Mystic Eyes of Death Perception" which is shown by having a rainbow-like color in her pupils. This supernatural ability allows her 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). A cut along any line will bifurcate the object, no matter how sharp the cutting tool and a stab at the point destroys the object's origin, causing instant death. 
Reunited with Mikiya, now employed as an investigator for a puppet-maker and powerful sorceress, Touko Aozaki. Shiki assists Touko's detective agency, "Garan no Dou", investigating paranormal events where she employs her combat skills to resolve the situation with force if necessary while struggling to come to terms with her identity.

Appearing as a puppet maker, Touko is actually a powerful sorceress. She runs a business in an abandoned building called "Garan no Dou". This agency sells their work, ranging from architectures to craftsmanships, to whoever is interested. However, Mikiya believes that Touko is simply forcing what she wants to make on the customers. As the company only consists of herself and Mikiya, she is the sole designer while Mikiya takes the secretary's job. Due to Touko's connection with the Magic Association, the agency occasionally takes on supernatural or otherwise abnormal cases despite Touko having run away and distanced herself from the organization long ago. She is the older sister of Aoko Aozaki, who does not have a particularly good relationship with her. In the early editions of the novel, Touko was portrayed with short blue hair. In the newer editions of the books and the movies, she has been given long red hair; Nasu and Takeuchi, dissatisfied with older illustrations of Touko, changed her hair color to reflect her relationship to Aoko Aozaki, who also has red hair.
She is very loose with money which leads to her being broke for months and unable to provide salary for her staff. Touko upgrades Shiki's artificial arm or gives other unique presents as compensation for her work.
She also appears in several Type-Moon releases such as "Mahōtsukai no Yoru", "Carnival Phantasm", "Chibichuki!", "Clock Tower 2015", "Fate/Extra" and "The Case Files of Lord El-Melloi II".

It is mobile, something out of the ordinary since Bounded Fields are usually impossible to move, and Araya typically uses it as a weapon. Moreover, he infused himself with a large building that makes it almost like a Reality Marble, solidifying Sōren as an exceptional mage. He is the mastermind behind the actions of the other antagonists by awakening their innate abilities and manipulating them to confront Shiki.

Director of the Sponheim Abbey, and acquaintance of Araya and Touko. They were on good terms until Cornelius realized that Touko was a better Mage than he was. Even though he was popularly considered a better Mage than her, he became so obsessed with this inferiority complex that he occasionally became deranged when speaking of her. He joined up with Araya, not because of the latter's goals but solely to kill Touko to prove his superiority. Though he is naturally more powerful than both Araya and Touko, he is blinded by his arrogance and is not nearly as versatile as they are. He used several spells in the novel, including one that had power equivalent to a Noble Phantasm, but none of them made an appearance in the movie.
