Amelia Wil Tesla Seyruun is the second princess of the kingdom of Seyruun, a realm known for its mastery of white magic, and the daughter of Crown Prince Philionel. Her mother was murdered when Amelia was very young, and her older sister, Gracia, left home afterward, events that deeply shaped her upbringing. At the time of her first appearance, she is approximately fourteen years old. Amelia is defined by an unwavering, loudly proclaimed devotion to justice, inherited from her father, and an energetic, optimistic, and relentlessly cheerful personality. She frequently delivers dramatic speeches about truth and righteousness from high vantage points, though she almost always loses her balance and falls, turning her entrances into comedy. Initially naive and prone to judging people by their appearance, she matures through her adventures into a more perceptive and nuanced young woman, learning that the world is not simply divided into good and evil. Her primary motivation is to fight for justice and protect the innocent, leading her to join Lina Inverse’s party. She forms a strong, sister-like bond with Lina, evolving from an admirer to a trusted friend. Her relationship with Zelgadiss Graywords begins with distrust due to his appearance but deepens into mutual respect and hinted romantic affection. She shares a sibling-like friendship with Gourry Gabriev and a polite, teasing rapport with Xellos, while her father remains a hugely important figure she seeks to emulate. Amelia is a highly skilled practitioner of white magic, proficient in shamanism, and knows some black magic. She prefers physical combat and created her own spell, Visfarank, which channels magical energy into her fists for melee attacks. Her signature powerful attack spell is Ra Tilt.
