Riseki is of an athletic built, standing at 185cm. He has short, dark hair, and wears 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.
