Ciel (シエル)

Ciel is first presented as a senior attending the same school as the main protagonist Shiki Tohno, where she is the president and only member of the tea ceremony club, and also good friends with Arihiko Inui, Satsuki Yumizuka and Shiki himself. Her outward demeanor is that of a calm, friendly, and peaceful person.


In the process, Ciel became a vampire and killed everyone in her village, the massacre only ended when Arcueid Brunestud arrived and killed her, fulfilling her duty of killing Roa whenever he reincarnates. However, unlike previous hosts, Ciel returned to life after Roa had moved on to a new host. The secret Vatican agency known as the Burial Agency captured her, and over the course of a month she was killed repeatedly by the Church, only to rise again on every occasion, because as a host of Roa while Roa was also inhabiting another, it was impossible for her to permanently die until Roa was killed. Despite their usual views on sorcery, vampires, and the like, the Church decided to use her abilities as a member of the Burial Agency, her main desire and mission being the elimination of Roa to end her eternal existence.
