The sneaky Tanakayama has now been reduced to selling goldfish for a living, and he has just one lone fish named Gyopo left to sell. Suddenly, he notices Gyopi floating towards him and hides in the bushes, leaving the pink fish to become acquainted with Gyopo. Though the pair takes an instant liking to each other, the selfish and wealthy Chitose insists that Gyopi is not allowed to date a 100-yen goldfish and forcibly drags him away. Now, with Tanakayama using their love as an opportunity to finally nab the multi-million yen fish and Chitose trying to sabotage their relationship, it seems that Gyopi’s only allies are Wapiko and the gang. But with Gyopo being whisked off to Europe, will they be able to stop her from leaving?
