Mia is the fourth princess of the Kingdom of Amaryllis in the anime Seven Sleeping Beauties. She has a youthful appearance and is often seen carrying a cherished teddy bear, an object that underscores her childlike side. Despite her young looks, Mia strongly desires to be treated and seen as an adult, and she tries to act mature and composed. However, this effort is frequently undermined by her easily frightened nature; she startles at surprising or tense situations, revealing that her confidence is still growing. Her motivation is rooted in this wish to shed her childish image and earn the respect of those around her, especially the prince Alec and her fellow princesses.

As one of the seven princesses awakened from a long curse by Alec’s kiss, Mia takes part in the shared life within the castle as the group works together to understand why the rest of the kingdom remains asleep. Her relationships with the other princesses are shaped by the contrast between her earnest attempts at maturity and their distinct personalities, which often lead to teasing or supportive moments. Over the course of the story, Mia’s development centers on gradually overcoming her timidity and learning that true adulthood comes from experience rather than pretense. No notable combat or magical abilities are recorded for her; her strength lies in her emotional growth and the bonds she forms with Alec and the other princesses.
