Dragon Ball DAIMA begins with Goku and company living peaceful lives before a conspiracy suddenly turns them small. What first seems like a bizarre new setback quickly points to a deeper plot connected to the Demon Realm, a world whose influence reaches far beyond Earth. As the heroes search for the cause of their transformation and a way to undo it, a mysterious young Majin named Glorio appears before them and becomes tied to the case.
The crisis pulls Goku into an unfamiliar adventure that extends beyond his usual battlegrounds and draws in Higashi no Kaioushin and Panzy as key figures in the journey ahead. Bulma, Vegeta, Piccolo, Majin Boo, Gohan Son, and Chi-Chi remain part of the upheaval as the story blends comedy, fantasy, and action around a cast forced to adapt to their altered bodies. Rather than centering on a tournament or a conventional invasion, the series follows Goku and his allies into the Demon Realm to uncover who engineered the conspiracy, understand the forces behind it, and restore the peace that was taken from them.
