Doraemon pulls out an ocean simulator that lets anyone wearing the goggles to actually simulate diving. They leave the machine pumping water for the night and then go around town scattering some fish food, ready to invite some real ocean life to take pictures with and brag about.
After a fun night out, the next morning they find a girl who turns out to be Princess Sofia of the Aquarians. She got lost through one of the portals Doraemon had set up but was amazed at the surface world. After a tour and meeting Nobita’s friends, she explains that her people migrated from Planet Aqua to Earth 5000 years ago – about the time when stories about mermaids first emerged on Earth. Now they live quietly in the deep seas. When she decides to return to the palace, Nobita and his friends join her with some help from Doraemon’s gadgets. On their way back, they are attacked and are mistaken as kidnappers. Shizuka manages to hide but she is abducted by the Aquarian’s enemy, the Kaiges who manage to track them down, determined to get their hands on the legendary sword. After Sofia clears up the misunderstanding, they have an audience with the queen Ordeen who tells them how their fight with the Kaige had made their Planet Aqua uninhabitable. A message arrived from the Kaige demanding they hand over the sword in exchange for Shizuka who was being held hostage. Unable to decipher the clue they had found, they didn’t know the whereabouts of the real sword so they decided to create a helper. There was little time left before the effects of the underwater gun were going to expire. They rescue her just in time and a fight breaks out. As Sofia prays for help, the sword reveals itself and the Kaige’s leader Buikin obtains the power, making Sofia’s army quick work.
After luring him out of the water, Sofia and the others manage to trap Buikin using Doraemon’s simulator. In the process, they find out the sword helps clear up polluted water and Sofia is happy they can return home to use it on their home planet. The heroes are welcomed back with cheers in the kingdom but they Nobita and his friends realize they’ve been away for too long.
With that, they say farewell and take the time machine back to before they met Sofia, ready to return to their everyday lives and wondering if they will ever meet again.
