A Goddess of Lastation and Ciel's senior.
Stoic and highly capable, she can get things done flawlessly all by herself. Her tsundere side comes out more around people she's close with, but she still has a deep sense of responsibility. She tries not to meddle in Ciel's governance, but she's keenly aware of the large difference in their approaches.

Lately, she's said to be hiding her identity to perform hero work from the shadows within Lastation. Cats are her favorite animal.

Noire's Goddess Form.
Her personality shifts to one that delights in battle. Her sense of pride doesn't change, but the embarrassment that holds back her emotions disappears, and she speaks more often and frankly.
