Kei Tsukishima  

Tsukki, 月島 蛍

Tsukishima is a member of Karasuno High's volleyball team and is known for being blunt and easily agitated. He tends to provoke others, often targeting Hinata, Kageyama, and even his seniors Tanaka and Nishinoya. Tsukishima dislikes "hot-blooded" individuals and prefers not to exert himself due to past experiences with his older brother. While he respects a few teammates like Daichi, Sugawara, and Asahi, he generally shows little regard for the others, becoming irritated when forced to be close to them, such as during huddles or training camp. Tsukishima can even be rude to Yamaguchi, his closest friend, which highlights his spiteful personality. His behavior is often seen as warped by his fellow second-years on the team. Additionally, he teases Kageyama by referring to him as "the king" and dismissing the rest of the players as common folk, which deeply angers him.
