Personality

Faust is a soft-spoken Sinner with a condescending manner of speech and high confidence in her intelligence. Despite technically being Dante's subordinate, she often takes the role of their informant and overseer, as she is privy to considerably more information than her fellow Sinners. Because of this, she has a consistent and unwavering faith in her abilities, and does not show any signs of panic even in troublesome situations. While her expanse of knowledge always proves helpful for the LCB, her egotistical attitude can be excessive. At times, she is outright and unnecessarily contemptuous towards others' inability to keep up with her pace, most frequently Heathcliff, as she appears to lack understanding for those who do not meet "Faust"'s high standards of intelligence.

As one of the more quiet Sinners, Faust frequently prefers to stand back and watch events unfold, often lacking in information she's permitted to indulge. She appears to be on a tight leash under the Gesellschaft, a communication net with the Fausts of other Mirror Worlds, which dictates how and when she is allowed to share knowledge, among other things. Her inability to access the Gesellschaft connection during Murder on the WARP Express is the first show of vulnerability in Faust, who grows more timid and uncertain as a result. In the face of such hardship, Faust is forced to rely on her coworkers' thoughts and observations, yet remains intent on attempting to maintain an indestructible image in front of the group despite them appreciating this more agreeable side of her. Still, she would come to realize the difficulty and uncertainty of a life without Gesellschaft, sparking some newfound empathy within her.

The Intervallo also makes it clear that by referring to herself in third-person, she is not actually referring to herself, but another "Faust". As Dante finds, many of her statements come off as considerably less haughty with the knowledge that she is not necessarily referring to herself as an individual. And although she can be strict and dismissive with the other Sinners, this seems to be a result of approaching matters with a strictly logical perspective, rather than any form of ill will. Her competitive and dismissive relationship with Hohenheim, by comparison, makes it clear that Faust's usual attitude isn't a product of hostility. This also demonstrates that even she is prone to bouts of pettiness. Furthermore, as her relationship with the Gesellschaft is expanded on, there grows an implication that Faust's arrogance is at least in part a result of her trying to compensate for the bullying and degradation she faces for being considered a failure among her peers.

Faust has been slightly less secretive about her situation following the incident on the WARP Train, and more understanding of the Sinners' personal wishes and inquiries. Additionally, she appears to have grown more comfortable confiding in Dante about her situation. Although still a know-it-all, Faust now comes off as a bit awkward and self-conscious, painting a more human image of her.
