Daigo, the son of renowned baseball player Gorou Shigeno, believes he has to live up to his father's name by becoming an all-star player himself. With great dreams, as soon as he reaches fourth-grade, he promptly joins the same little league baseball team his dad played on, the Mifune Dolphins. However, things don't go as planned. After only the first couple of practices, Daigo's lack of talent and inherent baseball sense shows, and his confidence is crushed. Unable to bear the pressure of living up to his father, a baseball prodigy, he quits the team in less than a year. Two years later, now in sixth-grade, a transfer student joins Daigo's class. This student turns out to be Hikaru, the son of Gorou's lifelong friend and fellow baseball star, Toshiya Satou. One day, Daigo's mother receives a call from the Dolphins requesting players for a game, so she forces Daigo to attend. To Daigo's surprise, he finds Hikaru there. Even more shocking is that despite his father's occupation, Hikaru has never played baseball before! Unlike Daigo, though, Hikaru immediately picks up the game demonstrating excellent performance. Needless to say, Daigo and Hikaru are polar opposites of each other. But this friction will inevitably thrust both of these inexperienced children into the world their fathers cherish—the world of baseball. [Written by MAL Rewrite]

Five elementary school children are spending their summer break camping at a remote mountain village. While on a hunt for their missing rabbit, Pyon-kichi, they find an injured dog in a field with crop circles. After nursing the dog back to health, they are shocked when he suddenly speaks and introduces himself as Pochi Rickman—an alien researcher who has been on Earth researching its plant life. As thanks for saving his life, Pochi offers to take the children to the moon on a sightseeing trip. When they arrive, the group quickly discovers that the moon hides a vast alien metropolis which they begin to gleefully explore. Unfortunately, after hearing that Pochi was severely injured on his mission, the government of the moon issues a travel sanction on Earth, preventing the children from returning home. Left with no other choice, the group journeys around the galaxy in search of a way to safely return to Earth. Amidst their adventure, they are pursued by aliens affiliated with "The Space Show," the universe's most-watched production shrouded in mystery.
