Lorna Endou is a primary member of the éX-Driver team, a group of specially authorized drivers who intercept runaway AI-controlled vehicles in a future where autonomous cars are the norm. She is a seventeen-year-old high school girl with long brown hair, often seen in a black-and-white one-piece dress with a striped neckerchief, dark-red fingerless gloves, and brown loafers. Her calm, professional demeanor and methodical approach make her the stabilizing force within the team, contrasting with her more impulsive partner, Lisa Sakakino. Lorna approaches missions with a calculated focus and exceptional technical skill, preferring lightweight, agile cars such as the Lotus Europa Special and the Lotus Exige, which match her precise driving style.

Her primary motivation is to fulfill her duty as an éX-Driver, protecting public safety from the dangers of hacked or malfunctioning AI systems. Over the course of the OVA and movie, her outlook deepens: she evolves from a strictly duty-bound operator into someone who personally values the preservation of manual driving culture, recognizing the balance between human intuition and mechanical reliability in an increasingly automated world.

Lorna maintains a close professional and personal partnership with Lisa Sakakino, often relying on each other’s strengths despite their contrasting personalities. She also acts as a mentor and elder-sister figure to the young prodigy Souichi Sugano, helping him integrate into the team and develop his skills. Her role in the story is central to the team’s operations, frequently serving as the strategist and the calm voice that guides her companions through high-stakes chases. She is a dependable, good-hearted individual whose development emphasizes the importance of human agency and passion behind the wheel.
