(Japanese: 月島つきしま 蛍けい, Tsukishima Kei) is a first-year at Karasuno High. He plays as one of the starting middle blockers on the boys' volleyball teamTsukishima is very tall and has an incredibly slim build for a volleyball player. Despite being a first-year, he is the tallest player on the volleyball team; standing at 190.1 cm. He has short blond hair, pale skin, thin eyebrows, and golden-brown eyes. He is often seen with a frown or a condescending smirk on his face. After joining the Karasuno volleyball team, Tsukishima wears the standard Karasuno volleyball uniform (black, orange, and white uniform with the number 11 on the back) during matches. He also wears knee pads and white volleyball shoes with green details. He is also the only player on the Karasuno team who wears glasses.Tsukishima is very blunt and will sometimes rile his teammates up due to his antagonistic nature (most notably being Hinata, Kageyama, Nishinoya, and Tanaka) and sometimes other teams because of his casual smug attitude, taking pride in and relishing when his opponents see him as a nuisanceDespite coming across as arrogant, Tsukishima has low self-esteem and thinks of himself as inferior to others in certain areas. This is first noted to be a surprise by Kuroo, who accidentally riles him up by suggesting he'll lose to Hinata, to which he says that he's already below him. After the Shiratorizawa match, despite being the MVP, he's seen calling himself lame for only being able to block Ushijima's spikes once, only adding to how little he believes in himself and his achievements. While he willingly admits his own faults, he does not like it when others point these things out, becoming annoyed and angry when Hinata tried to take responsibility in blocking Ushijima and then when Bokuto called his blocks weak in a sense of strength given how easily he got by him during practice. Knowing his limitations, Tsukishima reluctantly knows he must depend on others for certain things and gives his own version of motivation that is usually disguised as jabs at their skills or pride.
