ウルル＝カジュタ

The current Queen of the Dragons and the last Gold Dragon.  She calls Hime 'onii-sama' for reasons related to events previous to the story, and her trust in him is absolute.  Despite her appearance, she is well into her second century of life, but her essential personality in normal times is innocent (and easily manipulated by Opera).  Despite her seeming youth and innocence, she is capable of a degree of resolve that few others in the story can match.
