Kazane Kinomiya

Kazane Kinomiya is Shinra Kishitani's half-sister and the daughter of mother, Kaname Kinomiya. She makes her debut in the Epitome of Eighteen Histories side stories. She is motivated by wanting to know more about Shinra and travels to Ikebukuro to understand him.

History
Kazane travel to Ikebukuro in order to get to know her half-brother, Shinra. When she spots Shingen, she decides to stalk him for a while so she can understand him better too, adding him to her list of "observations". Kazane knows Shingen simply as her mother's ex-husband, to whom Kazane is connected by fate and not by blood. Soon, she becomes troubled by the question: why does Shingen wear a gas mask?

She is tasered and knocked unconscious and subsequently taken for examination by Emilia Kishitani, out of fear that she might have been sent by a rival of Nebula to spy on Shingen. When Kazane wakes up, Emilia explains her own actions and apologizes, realizing that Kazane was not a spy but the daughter of Shingen's ex-wife.

Kazane is baffled by the blatant kidnapping and even more by Emilia's broken Japanese. When Emilia asks if Shingen's ex-wife, whom Shingen left, is seeking reconciliation with Shingen by having Kazane stalk Shingen, Kazane herself is left shocked to learn who Emilia is: Shingen's current wife.

Realizing that the incident occurred due to misunderstanding, and as bad as the kidnapping was, Kazane was still doing bad by stalking a non-blood relative, Kazane lets the incident go. Emilia promises not to tell Shingen about it, and Kazane asks neither her brother nor Shingen know about it, to which Emilia agrees.

Upon finding out Emilia is Shingen's current wife, Kazane asks Emilia about Shingen's mask. Emilia informs her that the mask is worn in order to appear attractive and become popular. Emilia however, refuses to impart information on the Headless Rider, leaving Kazane to wonder if the Headless Rider is a robot built by Nebula to spy on her brother.
