Name: Yuma Taidan. 1st year. Same age as Kaito. Age: 15. He quit volleyball in his third year of middle school but started again in high school. He saw a team that didn't give up or throw away their pride even when the opponent was clearly stronger. Yuma wanted to play volleyball like that, so he joined the club again. His illness was discovered in his third year of middle school. That's why he quit volleyball once. He restarted in high school. Height: 180cm. Has some muscle. Weight: 65kg.
