Tsukishima Kei

Tsukishima Kei is presented as a young man of 1.90 cm tall, with the typical short blond hair. He presents a constant look of disinterest, with drooping eyelids at the edges, and thin eyebrows that often wrinkle in a slightly grumpy expression, glasses, and headphones most of the time. His skin is generally pale. His build is thin, but his hands are described as large and strong due to his volleyball skill.

Tsukishima Kei is characterized as cold and cynical, which some people may perceive as insensitive. However, throughout the series, Tsukishima begins to display a more caring and kind personality toward his teammates, especially his friend Yamaguchi. However, due to his generally cynical personality, he may not relate well to his partner's emotions and feelings, and may need a period of learning and adapting to a new relationship.
