Melbourne, Australia is currently the epicenter of an intense competition as youth tennis teams from around the world have gathered for the U-17 World Cup. The ultimate goal is to determine which country deserves to be called champion. Germany, victorious nine times in the past, intends to defend their crown against eager contenders such as Switzerland, France, and the United States. Despite being ranked low on the totem pole, Japan is not to be underestimated as their top middle school players have the potential to clinch a win. Leading the charge is the resolute Houou Byoudouin who is determined to showcase Japan's talents. However, before the official tournament commences, teams will partake in exhibition matches to showcase their skills. Unfortunately, Japan's fate puts them against a tough Germany, leaving little hope for victory. With former allies now turned adversaries, Japan must rise above the pressure and claim the championship for themselves.
