Thor von Flegel is the eldest son of Baron Flegel. He possesses a short stature, silver chin-length hair, blue eyes, and wears silver eyeglasses. This appearance caused him concern in his youth, as he was often mistaken for a girl, an experience that remains a source of embarrassment. He shares a long-standing connection with Prince August von Earlshide and Julius von Littenheim, stemming from childhood companionship. Thor later served as one of Prince August's primary escorts. Initially, their status difference led Thor to maintain formality, avoiding equal conversation. However, observing Shin Wolford interact with the prince without regard for hierarchy gave Thor the confidence to voice complaints and offer advice more freely. Academically, Thor holds sixth rank in the first-year S-Class at the Advanced Magic Academy. He is a member of the Ultimate Magic Research Society, led by Shin Wolford. Magically, Thor is proficient in Search Magic, enabling him to locate enemies within his vicinity, and Wind Magic, allowing him to summon powerful blasts capable of slicing through opponents. He harbors a strong desire to become a knight but remains self-conscious about how his physical appearance might impact this aspiration. In his personal life, Thor is engaged to a woman noted with humor as being significantly taller than him; their relationship is described as closely bonded. He also expresses a preference for dazzling silver accessories. Chronologically, Thor first appears alongside Julius during Prince August's interruption of a confrontation between Shin Wolford and Kurt Ritzburg. Throughout his involvement, Thor maintains a serious demeanor in his duties while gradually embracing more candid interactions within his social circle.
