Welcome to the Space Show

Five elementary school students embark on their summer school trip and soon discover their class pet rabbit Pyon-Kichi is missing. They decide to search for the rabbit despite the heat, turning a routine trip into a mystery. This search sets the stage for an extraordinary adventure beyond their hometown.

During the search, the kids find an injured dog in a corn field and rescue it. The dog reveals itself as an alien named Pochi Rickman and promises to take them to the Moon as thanks for saving him. The encounter marks the pivot from a simple school trip to a cosmic quest.

Pochi invites the kids to visit the Moon as a reward for their help. They agree and blast off with him, leaving their ordinary world behind. The promise of a bigger adventure fuels their excitement for what lies ahead.

A string of strange events strands the group on a voyage across the galaxy. They must navigate space and push toward Pochi's homeworld, Wan, so they can eventually return to Earth. The journey tests their courage and teamwork at every turn.

Neppo, host of the universe's most popular entertainment The Space Show, pursues them to harness the ship's power. His goal is to become a god, using the Pet Star and a powerful energy source called Zughan. Tension rises as the kids realize they are being hunted across the stars.

Natsuki carries Zughan, a substance tied to the wasabi root, in her bag, and Neppo closes in on it. The root also functions as a recreational drug, adding danger to the pursuit. The bag becomes a critical prize in the struggle between the kids and Neppo.

Neppo arrives personally as the children reach Wan, and the Pet Star's tractor beams steal Natsuki's Zughan bag. In the same act, Amane is abducted, escalating the crisis that could alter the fate of their world. The group realizes the stakes are higher than ever.

With friends they've made along the way, the children prepare for a climactic clash at Wan's interstellar festival. They outwit Neppo's guards using teamwork and tricks learned on their journey. The festival setting heightens the stakes and spectacle of the confrontation.

The kids mount a bold defense and defeat Neppo, rescuing Amane in the process. They also locate and rescue Pyon-Kichi, who had been kidnapped by Neppo's henchmen during the pursuit. Their teamwork turns the tide and stops Neppo from dominating the universe.

The group completes their mission by bringing Pyon-Kichi back to Earth. They return home aboard the Pet Star and arrive at their school just before their parents come to collect them, closing the summer adventure with memories that will last a lifetime.
