Flandre is generally a calm and cheerful character, but her emotional instability often leads to her being described as "rather nuts." Her interactions are childlike and unpredictable, with a tendency to become overly excited or overwhelmed by new experiences. Despite her powerful abilities, she is quite gentle in her demeanor, often seeking the company of others to alleviate her boredom and loneliness. Her limited exposure to the outside world has made her quite naive and unfamiliar with human customs. She has a deep respect for her sister, Remilia, and tends to mimic her behavior in an attempt to appear more sophisticated. However, her lack of control over her power means that she can unintentionally cause significant destruction when playing or expressing her emotions. She is 495 years old. Flandre pulled a prank on Marisa and stole one of her potions. Flandre drank it and it made her taller and more mature looking. Flandre is pleased with this outcome.
