Liselotte Cretia, formerly Minamoto Rikka—a Japanese high school student killed in a bus accident with Haruto Amakawa and Suzune Endo—was reborn into the Galarc Kingdom’s Duke Cretia family. Now the sole heir of a prestigious lineage, she is renowned as the kingdom’s most desirable noblewoman, celebrated for her beauty, intellect, and achievements. By fifteen, she graduated early from the royal academy, founded the globally successful Rikka Trading Company, and revitalized Amande as its governor, transforming it into a thriving economic center. Haunted by memories of her past life, she crafted modern goods like soup pasta and manju under nostalgic names to lure fellow reincarnators, driven by loneliness and a yearning for connection. Despite her aristocratic status, she governed Amande with meritocratic principles and ethical commerce, earning public trust. She defied arranged marriages, leveraging her accomplishments to secure personal autonomy. Liselotte’s striking light blue-silver wavy hair, gentle eyes, rounded face, and slender figure with a pronounced bust complement her poised, authoritative presence. Privately, she unveils a casual, modern demeanor around confidants like Aria, her loyal chamberlain and friend, who nurtures her emotional struggles and gently encourages her budding affection for Haruto. His competence and resemblance to her past-life crush, "Amakawa-senpai," captivate her. Their relationship began with mutual suspicion during Haruto’s incognito visit to her business. Gradually awed by his combat prowess and integrity, she revealed her reincarnation. Though initially cautious, Haruto grew closer to her, kindling unspoken romantic tension and leaving her wistful during his absences. She also reconnected with Latifa, Suzune’s reincarnation, through shared past-life memories. Politically, Liselotte rejected Hiroaki Sakata’s marriage proposal due to his misconduct and worked to mend her strained friendship with Charlotte Galarc, her childhood companion. As Amande’s leader, she implemented agricultural innovations and entertainment ventures, bolstering her reputation as a visionary ruler. Across light novels and the spin-off *Liselotte’s Wonderful Magical Trading Company*, her narrative contrasts her regal facade with private vulnerability. The anime’s second season expands her role, showcasing her resilience in defending Amande and uplifting its citizens, underscoring her evolution from a solitary reincarnate to a revered leader.
