She had brown colours for her hair and eyes. Even when she was younger, her hair was cut to shoulder-length and it was still the same style as teenager.
She was quite a spoiled child, being the only child in the Aoi's household. When she was younger, she refused to eat while Natsume was staying with their family. Her antics however did not get reprimanded by her parents.
Furthermore, she was also the daddy-girl type, it was always her father that consoled her whenever she was sad.
Natsume stayed for awhile at their house when they were both younger. Being the only child, Miyoko felt that her parents' attention had been shifted to Natsume.
In responsed to this, she started not eating her meal and refused to talk with Natsume. However, after she was consoled by her father, she began to talk with Natsume.
When she asked Natsume about his father, she got mad when Natsume mentioned that his father was very very very nice. She stated that her father was nicer than anyone else in the world.
The night when Natsume failed to return home, prompting the neighbours to help search for him, Miyoko was so mad at Natsume when she saw that her parents have to apologize to the neighbours. She blamed Natsume for bringing trouble to her family.
Miyoko again met with Natsume when he came to visit, getting the key for his house. She noticed that Natsume seems much calmer than he used to.
However, she changed her mind when seeing Natsume acting strange again. When Natsume rushed out from the house, she chased over him and blaming him again for not changing for the better. She even cried telling that her parents really do cared for Natsume.
Natsume instead told her that she should not worry, as he will not take away her family from her. Hearing that, Miyoko was stunned.
Later on her bedroom by the table, Miyoko remembers that she was rude to Natsume when they were younger. She regretted it.
