The King of Net Doubles

One of the protagonists is his own creation and the other is Echizen Ryuya. If you don't like it, don't criticize it. The two protagonists participated in the French Open World Cup and won that championship. They are only one and two years older than Echizen Ryoma respectively. With the help of another male protagonist, Echizen Ryuya did not leave Echizen's family, but returned to Japan to study when he reached his age. Before the Japanese team recruited junior high school students, they only guessed their identities and were not sure. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
