Description
Mireille Grangeon is a fallen noblewoman whose family's downfall led her to a wandering life of heavy drinking and dwindling savings. After her family's loss of status, she served as a tactician for Vasmarque Saremakia, son of the Duke of Missian, where her exceptional strategic abilities gained recognition.

She exhibits a lazy and eccentric personality, frequently found sleeping or drinking rather than engaging in routine activities. Despite her unrefined exterior and carefree demeanor, she possesses extraordinary intelligence and tactical prowess, making her a highly capable yet unconventional figure. Her blunt observations and perceptive nature, often putting her several steps ahead of others, sometimes cause friction with allies.

Discovered by the mercenary group Shadow, she was recruited by Ars Louvent, becoming his fourth retainer after an introduction facilitated by Fam. Some of Ars's retainers, particularly Rietz Muses, initially viewed her with suspicion due to her background and behavior, but her strategic value gradually earned their acceptance.

She holds the rank of general and serves as a key strategist and tactician within Ars's forces. Her intelligence surpasses that of fellow tactician Rosell Kischa, prompting an involuntary mentorship dynamic between them due to their similarly sharp minds.

Her younger brother, Thomas Grangeon, serves as an adviser to Vasmarque Saremakia and possesses significant combat strength. During the conflict between Vasmarque and his brother Couran, where Ars supported Couran, Mireille played a role in convincing Thomas to defect and join Ars's faction.

Physically, she has dark brown hair and brown eyes, standing 165 cm tall and weighing 68 kg. She formed a camaraderie with the mage Charlotte within Ars's group. Mireille contributes significantly to Ars's efforts to protect and strengthen his territory through her unparalleled military acumen.
