This is a 1980 sports comedy where a real baseball team plays against cartoon logic, and the cartoon wins every time. The humor runs on the specific cruelty of watching Tabuchi and the Seibu Lions get humiliated by their own incompetence, their own teammates, and the fundamental unfairness of a game that refuses to follow its own rules. It's absurdist, it's built on character caricature from an actual manga, and it treats a real sports tournament like a playground where the house always has the last laugh.

Tabuchi's heroics carry the Seibu Lions into the following stage of a baseball tournament, but what lies ahead will demand hard work and teamwork. His form keeps slipping, to the point that his shadow grows paler, and the Lions keep dropping games. Several fellow players show up at the stadium along with Dokaben to urge him not to give up, and a Tabuchi Day is held to prove how much he is valued. The celebration turns into a dismal flop. Adapted from Ishii Hisaichi's manga, the film is a sports comedy that sets caricatures of actual Seibu Lions players against cartoon characters.
