Heaven's Guardian

Thalia was always shunned, left to fend for herself. But then the Order found her, and she learned about a new existence. Now with a reason to live, she strives to become something great. (In Kanda's case, a great pain.) But when she hears disturbing voices in her head, learns of the prophecy, and remembers her childhood, her revealed purpose may turn out to be too much to handle.
