In the Ciel route, Shiki is much more fearful of and cautious around Arcueid; instead he spends more time around his upperclassmate, Ciel. They form a friendship and begin to care for each other. After Shiki and Arcueid defeat Nrvnqsr Chaos, they part ways. Ciel then reveals herself to be a hunter from the Vatican, who came to Japan to kill Roa Valdamjong. It was revealed that SHIKI Tohno was Roa's eighteenth body host in his quest for immortality, while his seventeenth host was none other than Ciel, who was born in 1976 in France as Elesia. After Roa took over on her sixteenth birthday, she killed everyone in her town. Arcueid had come to the town, killing her, leaving Roa to escape into his next host, SHIKI, leaving Elesia's body and soul to perish. Afterwards, her body was taken by the Vatican, where she suffered extensive experimentation in regards to her mortality. All that was discovered is that she could not die until Roa's soul was eliminated.
