Atosuryua Loy, also known as Atosryac Syun-Atos Lyuf Febdash Klowal Loïc, became Baroness of Febdash after her brother Klowal died in an incident involving Abriel Lafiel, an event that drastically changed her life. Previously desiring peace and comfort, she instead found herself compelled to fulfill noble obligations, including a mandatory military career in the Abh Empire's Star Forces. Now a Hecto-Commander, Atosuryua leads the Devastation Squadron, a fleet of assault ships which includes Lafiel's vessel, the *Basroil*. This role makes her the direct superior officer to Lafiel and her supply officer, Jinto Linn. Despite her initial lack of command experience and personal reluctance towards military service, she demonstrates competence and dedication. She is a conscientious leader, balancing loyalty to the Empire with responsibility for her subordinates, often displaying a friendly and approachable demeanor. Her relationship with Lafiel and Jinto is complicated by their involvement in Klowal's death. While she acknowledges her brother's unjust actions—imprisoning their father and unlawfully detaining Lafiel—and accepts his death as justified, she harbors lingering resentment over how it forced her into unwanted military and noble duties. She explicitly states she and Klowal had significant disagreements, particularly over their treatment of their Lander father, whom Klowal despised due to his own inferiority complex about their family's short Abh lineage. Atosuryua possesses the dark blue hair and golden or amber eyes characteristic of Abh nobility.
