Don Quixote (Hangul: 돈키호테, don-ki-ho-te) is designated Sinner #3 of Limbus Company's LCB department. Don Quixote is a rambunctious and steadfast woman with a strong sense of justice. She never parts with her shoes Rocinante on her quest to become a valorous Fixer of the City, and was previously associated with the amusement park of La Manchaland prior to joining Limbus Company. She is the focus character of Canto VII: The Dream Ending.
Don Quixote is a short woman with blonde hair styled in a bob cut and deep, round hazel eyes. She wears the Limbus Company uniform: a plain white shirt tucked under a black waist belt, a red tie, black slacks, worn brown running shoes, and a long black coat. Her upper body is thoroughly decorated with various Fixer merchandise. Notably, Don Quixote forgoes the Limbus Company uniform shoes and instead wears a pair of yellow shoes with the word "Rocinante" embossed on them. Don Quixote wears a variation of this footwear in nearly all of her Identities. Don Quixote wields a massive jousting lance named "SUEÑO IMPOSIBLE" that towers over her, indicating that she is much, much stronger than she initially appears to be. This fact is further supported by her dexterity with such a massive weapon and her effortless ability to pierce a human skull with it at short distance.
Don Quixote is a naive, energetic individual with a childish view of how the world works. She talks in an exaggerated, animated manner and jumps into any scene with enthusiasm, regardless of the gravity of the situation. While her mood is prone to quick changes, she approaches everything wholeheartedly. On a bus filled with hardened personalities, Don Quixote sticks out as incredibly friendly, silly, and over-the-top woman. Fitting of her knightly persona, she speaks exclusively in Shakespearean English. Don Quixote has an intense sense of justice and desire to protect the weak. She cannot stand to watch idly as innocents are harmed, and her desire to protect children is particularly strong. While this benevolent attitude is a respectable rarity in the City, it proves to be troublesome when paired with Don Quixote's high levels of impulsivity. More often than not, this determination to shield others from harm only serves to cause trouble for the people around her. Intervening during the separation of parent and child as the LCB's attempted to enter into K Corp.'s Nest led the Sinners to fight several unnecessary battles against the Wing's feathers in Canto III, just as engaging in a duel against a Cinq Fixer in Canto VII to convince him to rescue citizens ends up a bloody, fruitless cause. However, a reprimanding from Vergilius after the K Corp. incident did lead to improved behavior from Don Quixote, as she began to learn to think before she acts.
