Morisuke Yaku🪼٭★٭˚∘•

Standing at 165 cm, Yaku is on the shorter side. He has brown eyes and short sandy blond hair. Yaku is usually seen wearing the Nekoma training uniform. During matches, he wears the libero uniform consisting of a white jersey with red and black accents, red shorts, and knee pads. When playing, he normally wears white gym shoes with yellow accents.

Post-timeskip, Yaku's appearance has changed very little although his hair appears to be slightly longer and is now kept neatly combed back from his face. He appears to favor stylish suits as his regular attire.

Overall, Yaku is a rather honest, straightforward, and hardworking person who's very confident about his skills as a libero and looks out for his team, especially first-years Lev and Shibayama, and Kenma. He will frequently engage in lighthearted scuffles with his juniors, and will sometimes eat their food too.

Despite this, he can also be incredibly short-tempered, especially concerning Lev, who seems to find Yaku's angry outbursts "scary", although these outbursts are typically in response to Lev tactlessly commenting on Yaku's height and/or attempting to skip practicing receives with him. Even Kuroo at times refers to him as a "demon senpai". Yaku has also been shown to be insecure about his short height and it is well-known to be a taboo subject of discussion amongst the Nekoma players.

Yaku takes great pride in playing as libero, and especially considers it a huge honor to play as libero for Nekoma, a team whose members specialize in powerful defense. Off the court, he is supportive of his team and often takes on a parental role when speaking toward, or of them, which is similar to Sugawara. Because of this, Yaku and Sugawara are known to get along wel
