The new student of Katase High School, "A-Bian" Hoshino Yu (voiced by Katayama Fukujuro) and "Xiao Ye" Tsukimoto Makoto (voiced by Uchiyama Koki) are friends from the same table tennis dojo. A-Bian has a flamboyant personality, loves to talk and laugh, and because he is confident in his skills, he does not take his peers and predecessors in the table tennis club seriously. In contrast, Xiao Ye is introverted and calm. He does not seem to have any strong desire to win. Subconsciously, he hopes to be unnoticed like a robot. In order to meet the upcoming high school league, the table tennis club consultant Koizumi (voiced by Yara Yusaku) selected Tsukimoto for training. At the same time, the nearby Tsujido Academy High School transferred to the Chinese player Kong Wenge (played by Wen Yexing) who was kicked out of the national team. This person is arrogant and does not take the Japanese players with lower skills seriously at all. On the other hand, the Sea King Academy High School, which is full of masters, is also ready to prepare for the next competition. The square-inch table, the battle is fierce... This film is adapted from the original work of the same name by Matsumoto Taiyo.
