Goku and his companions arrive at the mystic Second Demon World where a giant ocean spreads as far as the eye can see! The party is amazed at the new world but is immediately attacked by Gendarmerie that have been sent by Gomah!

Vegeta’s battle with the Tamagami is evenly matched, but forced underwater where he's not used to fighting, he finds himself struggling! Vegeta is cornered and sinks to the ocean floor. But then he finally unleashes his true strength!

As Goku and his companions head to where Gomah is, engine trouble causes them to land on a certain planet. The place they land happens to be a surprise-filled planet where even Supreme Demon Kings are afraid to tread!
