Mio is the chief attendant and bodyguard of the Granado household, a position she carries out with unwavering loyalty and competence. Her background as a former orphan has given her a deep understanding of loneliness and isolation, making her especially attuned to the emotional needs of those around her. She is fiercely protective of her masters, particularly Marie, the younger daughter of the Shaderan family who becomes the fiancée of Count Kyros Granado. Mio’s personality is marked by a sharp tongue and a no‑nonsense attitude, but beneath that lies a genuine sense of empathy and a strong desire to protect the vulnerable. She is quick to act when she perceives injustice or ill intent: early in her service to Marie, she dismissed two maids who were deliberately worsening Marie’s already fragile self‑confidence as part of a long‑term scheme to become Kyros’ mistresses, an act that earned Kyros’ approval. Mio serves as both a guardian and a discreet confidante, offering Marie quiet support and reassurance. Her loyalty extends beyond mere duty—she actively investigates and confirms important family matters, such as verifying that Marie is indeed the biological daughter of her abusive parents. In the story, Mio is a vital supporting character who helps stabilize the new, kinder environment that Marie enters after leaving her own family. Her relationship with Marie is built on trust and gentle encouragement, while her interactions with Kyros are marked by mutual respect and a shared commitment to Marie’s well‑being. Mio does not undergo radical transformation herself; instead, her role is to be a constant pillar of reliability and perceptiveness. She is visually distinctive, with very long brown hair that reaches past her hips, blue eyes, and a maid’s uniform that includes a headdress and an apron, often with her hair styled in braids. Her notable abilities are those of a skilled bodyguard and attendant, combining physical protection with keen social intuition and investigative resourcefulness. Throughout the series, Mio remains a symbol of steadfast loyalty and hidden warmth.
