Kei Tsukishima 「月島蛍, Tsukishima Kei?」, is a first-year student at Karasuno High School; He plays as a middle blocker for the Karasuno Volleyball Club and is the younger brother of Akiteru Tsukishima.

Tsukishima is very tall and of average build for a volleyball player. Despite being a first year, he is the tallest player in Karasuno. He has short blonde hair and golden brown eyes. He is often seen with a frown or a cynical smile on his face.

After joining the Karasuno volleyball team, during matches, Tsukishima wears the black, orange, and white Karasuno uniform with the number 11 on the back. Additionally, Tsukishima wears white and green knee pads and volleyball shoes. He is also the only player on the Karasuno team who wears glasses. Since chapter 109 of the manga, Tsukishima began wearing prescription sports glasses (a gift from Akiteru) in matches.

Outside of matches and practice, Tsukishima wears a black gakuran, Karasuno's male uniform, and headphones around his neck.

Tsukishima is very short and has a habit of irritating people (usually Hinata, Kageyama, and even his senpais Tanaka and Nishinoya).

He dislikes "hot-blooded people" and does not like to exert too much effort due to his older brother's past experiences. Aside from others like Daichi, Sugawara, and Asahi, he has little to no respect for his other teammates and is shown to be quite irritated by having to be around them (seen as Karasuno joined together to build their spirits and again when he expressed displeasure of having to stay with the team during training camp). He can even be rude to Yamaguchi (the person closest to him) which really shows the spiteful personality of him. The second years think of him as someone with a twisted personality.

Tsukishima was much more cheerful when he was younger and had a very close relationship with his older brother, Akiteru Tsukishima. As a small child, Tsukishima seemed to really like volleyball, possibly due to his older brother's own love for the sport. However, Tsukishima's attitude towards volleyball (and club activities, in general) changed when Akiteru entered high school and became a member of the Karasuno High Volleyball Club.

Despite practicing very hard, Akiteru failed to become a regular player for Karasuno due to the number of more talented players on the team, including Hinata's idol, the "Little Giant". Seeing his older brother's disappointment, Tsukishima began to think that he should not put in so much effort anymore, just like his brother did, to avoid being disappointed if he fails.

Sometimes in elementary school, he sees Tadashi Yamaguchi being picked on. He doesn't do anything except call them pathetic. This was directed at both Yamaguchi and the bullies. After seeing how Tsukishima could stand up to people tyrannizing so easily, Yamaguchi begins to look towards him.

The only one he allows to be called Tsukki is Yamaguchi.

Her favorite food is strawberry cake.

It is said that she really likes dinosaurs.

Her hobby is listening to music, however, most of the time she does not do so while being with Yamaguchi.

In the manga's pilot episode, Tsukishima was a second-year high school student. Then, in the definitive manga he appears as a first-year student.
