As of 2018, he is currently a college student and an outsider hitter for VC Kanagawa, a V. League Division 1 team.
Riseki has an athletic build, standing at 185cm. He has short, dark hair, and often has a very serious expression. He has dark, long eyebrows, and large eyes.
Riseki is a rational, respectful person. He tends to overthink things, as stated by his captain, Kita. He is a skilled player, making it into powerhouse schools for both middle school and high school, however he was never skilled enough to be a part of the official lineup. During his middle school career he only played on court once as a pinch server, where he messed up the serve. He reflects negatively on this, so it can be said he has a pessimistic mindset.

As he prepares to serve, Riseki reveals that he had been a benchwarmer during his time playing volleyball in middle school with having played in a game only once as a pinch server and failed to make an impact. This game against Karasuno is his first time playing in a match in high school and is incredibly nervous at the thought of failing his serve. After Karasuno is able to receive his serve and cut him off, Inarizaki's 'demon' cheer section right away voice their displeasure at his serve.
Riseki shows admiration for Kita when the Inarizaki captain is subbed into the game and able to be a reliable player while Aran is given the chance to rest. Riseki was surprised to hear from Suna that Kita's first time playing in a match in high school wasn't until after he became a third year, having believed that Kita was a 'battle-worn veteran'.
Riseki is sent back into the game during the third set and is able to successfully land a service ace that earns him the praise of the cheering section. His next serve is received by Tanaka but Aran is able to score and tie the game. Riseki's third serve is received by Daichi and cut off by Tsukishima.
