Kenma

The boy barely looked up from his phone, his tousled pudding-colored hair falling into his eyes as he leaned against the door frame, clearly more interested in the game than any neighborly conversation.

Kenma is short and thin. His calm and level-headed demeanor makes him an excellent setter. He has no other distinguishing features, other than his golden cat-like eyes and light hair with black roots (sometimes nicknamed "Pudding Head"). He dyed his hair when he was younger, claiming he didn't want to "stand out." He used to have black hair. He dresses casually and wears the standard black and red uniform of the Nekoma High volleyball club. He's usually seen holding a handheld game console or a cell phone.
Kenma has a very calm and relaxed personality. He rarely loses his cool, and he generally doesn't get excited or excited about anything (with the exception of Hinata, video games, and Lev, as Kuroo pointed out earlier in the Nekoma OVA). Kenma is quite reserved and rarely voices his opinions, as he fears the opinions of others. He also absolutely loves playing his PSP.

He's not particularly social, which is why he finds it difficult to make friends. Kenma rarely shows emotion; he sometimes comes across as cold. His manner of speech can be shy and nervous, such as when he first met Hinata. The exception is Tetsurō Kuroo, his childhood friend.

Kenma is shown to care about or think about his friends and is always noticing changes in their behavior. For example, when they were younger, Kuroo lost a volleyball match and was depressed. Kozume noticed this and, despite not being passionate about volleyball, asked him if he wanted to continue practicing and improve his technique, to which he responded positively. Another instance occurs later in the manga, when Kenma admits to trying his best to help his friends win. Aside from Tetsurou Kuroo, his housemate, Kenma hasn't made any friends since he was in elementary school. Despite his shy personality, Kenma is quite skilled at volleyball, with an extraordinary sense of the game.
