The story follows Laura Edmonds, a nine-year-old prodigy with a secret talent for magic, a stark contrast to her parents' staunch belief that "Frontliners are the best" and their disdain for magic users. Her parents, Bruno and Dora, were renowned adventurers who achieved great feats as frontline fighters, instilling in Laura the ambition to become a swordswoman like her father. Despite her parents' disapproval, Laura discovered her magical abilities at a young age, accidentally conjuring fire and later healing a cat. She suppressed this talent, focusing on sword training, which she excelled at, leading her parents to enroll her in the prestigious Royal Guildrea Adventurer Academy at an unusually young age.
Upon entering the academy, Laura, a sword prodigy, is unexpectedly placed in the magic department due to her astronomically high magic aptitude scores, a result that shocks everyone, including herself. This placement is justified by the academy's philosophy of nurturing talent, regardless of initial aspirations. Laura is dismayed, as her heart is set on being a swordswoman, and she struggles to reconcile this with her overwhelming magical potential. She meets Anna Arnet, a talented swordswoman who becomes a potential rival, and Charlotte Gazeard, a seemingly arrogant but passionate magic student who initially views Laura as a rival due to her immense power.
Laura's first practical magic test is a disaster, as her raw power obliterates the summoned elemental target and damages the training grounds' protective barrier, revealing a level of magic far beyond comprehension. This incident leads to a confrontation with her teacher, Emilia Acland, a powerful adventurer known as the "Dragon Slayer," who is angered by Laura's dismissive attitude towards magic and her perceived lack of effort. To settle the dispute, Emilia challenges Laura to a magical duel, with the condition that if Laura wins, she will be allowed to practice swordsmanship after classes. Laura, fueled by her passion for swordsmanship and her parents' teachings, accepts the challenge, determined to prove her dedication to the sword.
Meanwhile, Charlotte, initially resentful of Laura's overwhelming talent, begins to see Laura's genuine passion for swordsmanship and her struggle with her unexpected magical destiny. Despite their rivalry, a grudging respect forms between them. The narrative concludes with Laura and Charlotte becoming roommates, their relationship marked by a competitive spirit and a shared ambition to excel, hinting at future challenges and the development of their unique talents within the academy.
