Together, Ciel and Shiki confront SHIKI, and almost destroy his soul, until Arcueid returns to kill him, where she only destroys his host body. Roa's soul takes refuge in Shiki's body, as the two became connected after SHIKI had murdered Shiki when they were kids. This starts to drive him insane. Ciel reveals that she knew that Roa was now inside Shiki and tries to destroy both their souls, but is unable to do so due to her affections for Shiki.
