Unlike the main television anime series which is mostly set in modern-day Japan, the new series will be a "sealed room" suspense comedy set 100 years in the future. The story begins when Shinnosuke and the entire Nohara family wake up from cold sleep to find themselves aboard a space ship drifting in space. The anime will depict the various events that take place inside the ship.

One night, the Nohara family were enjoying a pleasant dream, when suddenly a big fish appeared in their dreams and ate them. The next morning, Hiroshi read in the newspaper that everybody in another town had the same nightmare as him, but it seemed to have ended. But Hiroshi also heard the same dream from Misae, Shinnosuke, Himawari and even Shiro. They were surprised and thought if the same thing is happening in Kasukabe too. In kindergarten, on telling others about his nightmare, Shinnosuke was surprised to know that everybody too had the same dream. Then a mysterious girl named Saki was transferred to Futaba Kindergarten and joined Shinnosuke's class. Everyone in the class, including the rather inactive Bo-chan, were all excited and happy on seeing her. But Saki had a cold attitude and didn't get along well.

Something sinister's afoot in Kasukabe. Shin-chan doesn't know what it is, but he's pretty sure it involves samba-dancing doppelgängers.

There's only one way to stop a filthy evil scientist from destroying the world, and it's with a powerful hot spring located under Shin-chan's house!

They are neither animals nor humans. They cannot be distinctly categorised as boys or girls. They are also not considered to be Earthlings or space creatures. There are no such specific titles in the world of Coji-Coji. Instead, it boils down to the meaning of "existence", an emphasis on the root of a character. This world hinges on all things natural, the pure existence of life. The protagonist, Coji-Coji, represents a perfect existence where truths of life are constantly being delivered and no words of malice can be spoken.

After a motocross accident, Show Zama was pulled from Japan into the mystical world of Byston Well, where he and others from Earth were reicruited by Lord Drake Luft to pilot his newest weapons, the Aura Battlers, a combination of Byston Well magic and Earthien technology. However, in the heat of battle, Show is approached by Marvel, a woman from Earth, who convinces him of Luft's sinister intentions.
