The Japan U-17 training camp welcomes back the Foreign Expedition Team after a month-long absence. Comprised of 20 players with unparalleled strength and technique, the team surpasses those on the top court. The coaches reveal that only 20 of the best players will be selected for further training, causing tension as only high school students are chosen. The middle school students rise to the challenge, determined to steal the 11th to 20th positions. Delayed arrival of the "Genius 10" initiates scheming amongst the middle school students. Unlikely pairs join forces, combining skills to defeat the top 10 players in a battle of strategy and talent. All strive for the honor of representing Japan at the U-17 World Cup.
