An adventure set in a south island. Shinnosuke with his parents and friends joined a tour with the preview of Action Kamen’s new movie ‘South Sea Millennium Wars’ on a luxury liner, but a funky guy who names himself Paradise King and his slave gang of gibbon monkeys took away all the adults to a south island. Gotaro Go, an actor playing the role of Action Kamen, with Shinnosuke, fights a martial-arts battle and air battle against Paradise King.
