Don Quixote is a rambunctious and steadfast woman with a strong sense of justice. She wants nothing more than to be affiliated with the Fixers she idolizes so heavily to the point of delusion, having earned her own Fixer Identification Number prior to recruitment.

Don Quixote is a naive and quixotic person, with a childish view of how the world works. She consistently talks in an animated, exaggerated manner, and jumps into any situation with enthusiasm, regardless of the death or suffering involved. She notably speaks exclusively in Middle English, seemingly in an attempt to take on a more "knightly" persona.

Don Quixote has an intense sense of justice and desire to protect the weak, as she violated a Taboo in front of K Corp personnel after they forcibly separated a child from his parent and beat a gang member for threatening a pawn shop owner.

Don Quixote is extremely impulsive and has a propensity for violence, remorselessly impaling Ryōshū straight through her head in retribution for killing Ishmael and Heathcliff during an argument they were having. This tendency was shown again in Canto III when she pummeled Sinclair hard enough to splatter blood all over herself, in an attempt to return him to his senses and "for justice." This impulsivity mixed with her insatiable thirst for justice makes it difficult for her to follow orders and often results her endangering her fellow Sinners and disrupting plans (and possibly fail the mission), much to their, or Vergilius' frustration and misery. She, however, appears to avoid any mention of this particular fact whenever possible.

Don Quixote has an affinity for anything Fixer related. She idolizes some of the most famous Fixers, such as the Grass Maiden, Siegfried, and the Red Gaze, though she has an obvious admiration for all of them, as shown in her interactions with the Molar Office Fixers and Nelly. She prides herself on her collection of Fixer merchandise, and knows a large variety of information about Fixers and Associations in general.

In her true form as a Bloodfiend, she is haughty and imperious, exuding an air of aristocratic elegance, with a sense of superiority and entitlement. Her personality is be marked by a dramatic flair, often speaking in a refined, eloquent manner with an underlying tone of condescension. She views herself as a noble protector of lesser beings, seeing others as mere pawns in her grandiose quests, while also perceiving any insolence from her lessers as unacceptable.

Her obsession with chivalry and knighthood is translated into a vampiric code of honor, believing herself to be a guardian of ancient traditions and the true essence of nobility. Despite her haughty demeanor, there is an undeniable charisma to her presence, drawing people in with a mix of allure and intimidation.

However, beneath the grandiosity, there is demonstrated a tragic and delusional aspect to her character, as she clings to outdated ideals and refuses to acknowledge the changing world around her, seeing herself as a timeless figure above the mortals she interacts with.
