Nekoma High School's volleyball team signs a new recruit: Lev Haiba, who is half-Japanese and half-Russian. Although this self-proclaimed ace possesses impressive height, he is deficient in fundamental volleyball skills. This deficiency causes significant difficulty for the team's setter, Kenma Kozume, when they are paired together. Contrary to everyone's expectations, Nekoma's coach proposes that Lev participate in the practice match against Kunihira Senior High School, leaving Kenma with no option but to collaborate with the tall player. Will Kenma manage to surmount this new challenge?
