11

Arcueid escapes, prompting Ciel to reveal she is the White Princess of the True Ancestors. Roa gave her a blood-stained rose, creating a cycle where she awakens briefly to kill him before sleeping again. Shiki pursues Arcueid but encounters Roa and Akiha. Roa overpowers them until Ciel arrives, only to be defeated. Roa retreats while Ciel heals her injuries. At home, Shiki learns he was adopted and swapped places with the real Shiki Tohno after the original went berserk. Shiki then visits Arcueid at her apartment, where they make love. Upon waking, he finds a note reading "Bye, Bye."
