With the arrival of the U-17 World Cup, youth tennis teams from all around the world gather in Melbourne, Australia to determine which is the best. With nine-time champion Germany vying to defend their title once more, and powerhouse nations-Switzerland, France, and the United States-determined to make things interesting, the road to victory is perilous. Although Japan is sitting at the bottom of the rankings, the addition of the nation's strongest middle school players has reinvigorated their chances at winning. Captained by the ruthless Houou Byoudouin, Japan is ready to show the world what they are capable of. However, before the real competition starts, the teams will have a chance to prove their strength through exhibition matches. As luck would have it, Japan is slated to face off against defending champion Germany-a match they are likely to lose. To make matters worse, old allies have suddenly reappeared as sworn enemies. Before Team Japan crumbles under the pressure of the international stage, they must rise from the ashes and claim the title for themselves.—MAL Rewrite

Echizen Ryoma, who was ordered to withdraw from the Japanese team training camp for breaking the norms, was invited by his brother Ryuga to participate in the U-17 World Cup as the U.S. team; at the same time, Tezuka, who went to Germany to enter the tennis world, also joined the strongest German team, and the two became the enemies of the former teammates of the Japanese team. The U-17 World Cup is about to open with the best players from all countries.—iQ
