Amelia Rose, scion of the prestigious Rose family among the three major noble houses, enters Arnold Academy as a first-year student. She possesses striking red hair styled in twin tails adorned with rose-shaped ornaments, matching red eyes, and a fair complexion. Her typical attire is the academy uniform: a skirt, vest, stockings, and a signature red tie. Her personality blends nobility with approachability; she treats peers respectfully regardless of social status, rejecting class-based discrimination. Beneath this composed exterior simmers a passionate and occasionally jealous temperament, particularly in romantic situations. A competitive nature surfaces, exemplified by a past incident where losing a match to childhood friend Ariane led to prolonged estrangement, revealing a tendency toward sore losing. She maintains a complex friendship-rivalry dynamic with Rebecca Bradley, centered on mutual affection for Ray White. Her magical abilities focus on fire-based offensive spells and the unique Butterfly Effect technique, manipulating causality to redirect attacks and render her nearly untouchable. This power manifests as glowing red eyes and pink magical butterflies capable of detonation. However, overexertion risks overheating her brain's engram, causing nosebleeds and physical strain. Later training under Ray White enables her to integrate explosive properties into her butterfly constructs, enhancing combat versatility. Character development includes reconciling with Ariane after years of estrangement, demonstrating emotional growth. Romantic feelings for Ray drive significant actions, including clingy jealousy when he interacts with other girls and participation in rigorous sorcery swordsman tournaments following his intense training regimen. Despite noble privileges, she experiences loneliness and emotional vulnerability, finding comfort in a stuffed bunny. Her background reveals childhood ringlet hairstyles exchanged with Ariane during adolescence and ongoing pressures as a noble heir expected to uphold family honor. These expectations contribute to her initial reluctance to form genuine connections, though she gradually cultivates authentic friendships at the academy. Her journey reflects a balance between aristocratic duty and personal desires, navigating magical development and interpersonal challenges within the school's competitive environment.
