Kiyoko Shimizu

Kiyoko Shimizu is a third-year student at Karasuno High. She served as one of the managers for the boys' volleyball team for the majority of the series.

She has an average height of 166cm and weighs 52kg. Kiyoko is a girl with shoulder-length black hair that she tucks behind her left side, while the rest hangs on the right side, with a single small hairpiece hanging in the middle. She has grey eyes with visibly long eyelashes, a distinct mole located on the lower left side of her chin, and she wears square-rimmed glasses with pink rims and a bridge.

She is often described as extremely attractive, though some may consider her "erotic," which draws a lot of attention from both male and female students, including students from other school teams. Due to her appearance, Karasuno High is known as the team with the beautiful manager. Many find her attractive and refer to her as "Glasses-chan" or "Goddess Manager."

Kiyoko usually wears a white tracksuit that conceals her medium-sized breasts. The jacket and sweatpants both have a single periwinkle stripe on the sleeves. Outside of club activities, Kiyoko is seen wearing a pair of black tights with her school uniform, regardless of the season. This is mainly to hide the scars she received from her days as a hurdle jumper.

Kiyoko is known for her aloof and straightforward personality. She takes her role as the volleyball club's team manager very seriously and is passionate about it.

She also deeply cares about the team members in the volleyball club. Surprisingly, she can be quite shy when it comes to giving speeches, such as when she wishes the volleyball team the best of luck.
