Rintarō Suna!

Suna has dark brown hair, slightly combed down, with a few strands sticking out on the top of her head and bangs parted in the middle. She has narrow, grayish-yellow eyes and thin eyebrows. She is often seen with a blank expression.

After the timeskip, Suna's hair is now a little shorter and her body has become more muscular.

Suna appears to be an expressionless and calm person. He is more expressive with his thoughts, wishing he could find a reason to tease Kita or make sarcastic comments against Tsukishima and Tanaka. He is also quite analytical, being able to manipulate opposing blockers and discovering that Tsukishima was baiting him into shooting around his block. He tends to slack off when his team has a big lead in points and appears to be winning the game. However, he is shown to quickly return to normal when he notices Kita watching him.
