Nyx goes to Angelique's school to ask her to aid him in protecting the world of Thanatos and come live with him at the Hidamari Mansion. Angelique declines, saying she wants to be a doctor and she is not willing to give up her schooling for it. Nyx states having the power to do something but not use it is a sin. Not soon after the meeting, while chasing after a stray cat, she stumbles upon an injured boy whose name is Rayne. In the midst of caring for Rayne in her room as well as hiding him due to it being a girl's dorm, a Thanatos appears and begins attacking fellow girl students. While fighting the Thanatos Angelique discovers that she has a special power. It is revealed she is the Queen's Egg, the only female purifier in the world as well as candidate to be the Queen of Arcadia. (thetvdb.com)
