Suna appears to be a deadpan, quiet person, more expressive with his thoughts, wishing he could find a reason to poke fun at Kita/make snarky remarks against Tsukishima & Tanaka. He's quite analytical, being able to manipulate the opposing blockers & figuring out that Tsukishima was baiting him to shoot around his block & tends to slack off when his team has a huge point lead & seems to be winning the game, but he is shown to quickly get back on track when he is aware that Kita is observing him.
