Kiyomi Suna

Kiyomi Suna (砂清美, Kiyomi Suna) is a first year student from Inarizaki High and the Volleyball team's manager.

Appearance
Kiyomi has dark brown hair down her back with long locks down the front, set in the middle of big olive-colored eyes. Her face is rather thin, like her nose and his features. Her ears are often seen with gold earrings and a few thin colored bracelets on her wrist. She often wears a surgical mask because of allergies. She also has a mole under her right eye.

One outfit in which she is usually seen is the typical Inarizaki uniform with a short skirt and a light waistcoat. It should be noted that she often wears her brother's red volleyball jacket, which is slightly too large.

She is recognized as very pretty by the Miya twins.

Personality
She is considered one of the smartest students at Inarizaki High School.

Kiyomi has a very indirect way of speaking, similar to Kenma, where she very often withholds her words when expressing her opinion. For this reason, his teammates are constantly listening to her, being very attentive. Despite her outward appearance, Kiyomi cares a lot about her teammates.

We see her during the match of Karasuno vs Inarizaki, she squirms, crying and imagining the worst for her brother. She is even seen cheering Atsumu with tears in her eyes despite the match.

On the pitch, Kiyomi does the right thing and is confident in her skills. Not in an arrogant way, but she's so confident in her skills in the presence of her teammates.

Despite her reserved manner of speaking and bland expression, she does not hesitate to severely reprimand the twins for their childish behavior in the middle of a game.

Kiyomi also has a strong analytical side which can be seen whenever she talks to the coach and the team about how they play.

Background
Kiyomi attended Seijo High School and performed there as a setter. In his college, his volleyball teammates had adequate skills, but they did not have a strong passion for the game.

She then decided to join the high school where her brother was located, who according to him, was perfect for her and her ambitions.

Suna Rintarou

She is very close to her brother. She cares deeply about her well-being as a little sister. Both share a relationship based on trust and listening. Not being loud and obnoxious, they are able to understand each other well without ever getting angry. Rintarou once told the team captain that he considers himself lucky to have a sister like his.

They are often seen interacting with regards to team decisions and are usually the ones the coach comes in to when dealing with the team.

Miya Atsumu

At first, she didn't like him very much, she found him way too boring and noisy for her taste. The two were definitely not compatible. According to Atsumu, their relationship at first came down to simple greetings without looking at each other.

But little by little, after his accident, and as the manager of the team, Kiyomi became closer to him, encouraging him and congratulating him on his magnificent gestures in the match.

A romantic relationship then developed between the two students, teasing each other all day long, before forming a couple.

Miya Osamu

Being the manager of the team, Kiyomi was able to sympathize with the many players. She then met Osamu who seemed much calmer than her brother. The two then liked each other, becoming very good friends despite Atsumu's slight outburst of jealousy.

KIta Shinsuke

The captain and manager get along extremely well, behaving very well to each other even though Kita's outspoken and straightforward personality makes Kiyomi very uncomfortable.
