Maria Campbell is a central character in the story, functioning as the original heroine of the otome game Fortune Lover within the narrative. She is a kind-hearted, humble, and gentle young woman who possesses a rare and powerful form of magic known as light magic. Maria was born into a commoner family in a small border town, and her light magic first manifested when she was five years old, healing a friend’s injured foot. Because of her commoner status, she was shunned by her community after this event. She eventually becomes the first commoner in over a century to enroll in the kingdom’s magic academy, where she faces bullying and isolation due to her class. Her natural personality is calm, hardworking, and positive; she rarely defends herself at first, often putting others’ needs before her own, and has a tendency to be overly accommodating. Over the course of the series, she grows more confident and develops a strong desire to protect those she cares about, especially her friends.

Maria’s role in the story shifts dramatically from the game’s original plot. Instead of being romantically saved by the male love interests, she forms a deep and transformative friendship with Katarina Claes, the series’ protagonist. Katarina actively befriends and protects her, which leads Maria to become a loyal and devoted companion. This bond is central to Maria’s character development, as she comes to value Katarina’s kindness above all else. By the end of the first season, Maria admits that the person she loves and wishes to stay with is Katarina herself, a confession that redefines her original role in the game.

Maria’s key relationships extend beyond Katarina. She becomes close to the other characters who are drawn into Katarina’s circle, including Geordo, Keith, Alan, and others, though her strongest emotional tie remains with Katarina. Her background as a commoner with rare magic also makes her an important figure in the world, as her light magic is capable of healing and countering dark magic. In addition to her magical ability, Maria is academically gifted and enjoys baking, a hobby that Katarina encourages. Her development from a passive, bullied heroine into a self-assured and caring individual who actively seeks to protect her friends is a notable arc within the series.
