Miyuki is a "young lady" from a wealthy family whom is also beautiful, smart, and well-mannered. She was the president for her grade level in her first year when she became great friends with Kagami. Now Miyuki is the same class as Konata and Tsukasa. Miyuki is more relied on by her classmates in helping their studies than Nanako.
Miyuki's physique is average, but she has excellent proportions; she has large breasts that Konata analogies her to a cow. Her appearance is as follow: has long light pink hair, and her eyes, covered by the glasses she wears, are light bluish-purple. She is a stereotypical "healing-type" meganekko. Her vision is less than 0.1, though used to be good until elementary school when she started reading books in the dark after her mother dozed off in the midst of reading them to her in her bed. She likes to read books, but does not read light novels.
Miyuki loves to sleep, and she always goes to sleep at eleven. She used to go to sleep much earlier at ten before her second year. However, she hates going to the dentist, but she frequently has to go there to fix a loose crown or because of tooth decays. On the rare occasion that she plays video games, her personality seems to change.
