Apologetic Attacker: So far she's had a quick exchange with Cassidy and a showdown with Narcissa. Each time, she apologizes repeatedly for everything in it, including during the battle.
Badass Adorable: Though she's shy, withdrawn, polite, and doesn't like fighting at all, she's also has defensive skills and speed nearly equal to Cassidy's. She furthermore has revealed herself to be a competent staff fighter, including beating Narcissa with a single strike.
Hypercompetent Sidekick: To Vincent. She handles all the business detail as his assistant, arranges anything they need, and can kick ass if it's called upon.
Martial Pacifist: Capable of defending and fighting, but prefers to do so only in self-defense or defending otherwise alongside uses violence only when there are no other solutions. Otherwise, she hates fighting at all and will avoid it unless no other choice.

“Love was just a word to me until you gave it meaning. I've been taught that one’s soul mate is the one who make life come to life. You do that for me, you really do. I've also been taught that soul mates are those who bring the best out of each other. I can already feel you bringing the absolute best out of me. It would be irresponsible and selfish of me if I did not return the favor…”

From his perspective, he treats the entire conflict as a game while also holding feelings for Grandmaster because she opposes him and seeks a Battle of Wits between two.
Allergic to Routine: Entire motivation for being a Diabolical Mastermind is because he's otherwise bored, wants something to do, and has no problem being a villain.
At Least I Admit It: About being a selfish bastard who doesn't care about anyone else. As he sees it, everybody is a selfish person who will do anything possible given the right justification. He doesn't fabricate he's anything else.
Bad Boss: Only helps others out for sake of his own amusement seeing what happens. Whatever they succeed or not is not his problem. He'll cheer for their destruction, ruin their lives to force to work with, or exploit people in short term for his long term profit so long as he finds it entertaining.
Lack of Empathy: Doesn't give a damn what happens to anyone and sees anyone or anything as things to satisfy whatever selfish need he wants.
Laughably Evil: Deus is, without a doubt, a horrible person who has shown no redeemable qualities yet. However, his lack of subtlety, jovial ways, dark sense of humor, and crass nature make him more hilarious to people than evil. Until he goes too far.
Unsexy Sadist: Towards Grandmaster. He both enjoys the Arch-Enemy status between them, attracted to her, plays sadistic mind games with her, and creates challenges for her to test abilities so two can fight with one another. Cassidy, however, is more angered and considers creepy for these reasons.
