Personality
Adagio is a very scheming and manipulative individual, only concerned with being adored by others. She displays a large degree of sadism, often taking pleasure/advantage of people's insecurities, and a considerable level of intelligence. She has a deep resentment over losing her powers and being trapped in the human world. She also shows no respect to their fans, often calling them "human scum" under her breath.

Aria Blaze & Sonata Dusk
Adagio bears contempt toward her sisters, openly calling them "idiots" and generally disliking their company, Sonata mostly just because she's just an idiot, and Aria for questioning her authority.
