yes,in primary school.l do not know who wins,in the match,tezuka defeated sanada and then met yukimura. I have heard that yukimura was the champion,but I do not know if that was true
they have a match about years 前 and i dont know if tezuka is already the captain of seigaku back in that time. tezuka defeated the emperor- sanada and when yukimura saw it, he challenge tezuka to have a match with him. tezuka didnt refuse but i dont know who won in that match because its not stated in the manga
Um... Hope I can help but I have heard that the explanation can be found to one of Prince of テニス OVAs, Another Story, in Rikkai's part though. It's really nice! Your 回答 have answered also my 質問 when I was also wondering that question.
