Crayon Shin-chan the Movie: Super Hot! The Spicy Kasukabe Dancers

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

Class 1-A visits Nabu Island where they finally get to do some real hero work. The place is so peaceful that it's more like a vacation... until they're attacked by a villain with an unfathomable Quirk! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.

All Might and Deku accept an invitation to go abroad to a floating and mobile manmade city, called 'I-Island', where they research quirks as well as hero supplemental items at the special 'I-Expo' convention that is currently being held on the island. During that time, suddenly, despite an iron wall of security surrounding the island, the system is breached by a villain, and the only ones able to stop him are the students of Class 1-A.

Shin-chan is all set to challenge Kung Fu in the Chinatown of Kasukabe city, known as Aiyā Town. He and the Kasukabe Defence Force are going to put up a totally no-stunt Kung Fu challenge on the stage.
