Fifty years ago, the wielders of the sacred Rave stones fought against an onslaught caused by demon stones called Dark Bring. This war resulted in an explosion known as "Overdrive"—a blast so powerful that it sent the Dark Bring into a deep slumber and scattered the pieces of Rave across the world.

In the present, Haru Glory lives a peaceful life on Garage Island until one day, he catches the creature Plue while fishing. Plue is later recognized by Shiba Roses, an old man who happens to be the original Rave Master. Shiba explains that the Dark Bring has resurfaced, and that to stop it, assembling the scattered parts of Rave is of utmost urgency. However, before Shiba can leave on this mission, he is attacked by a soldier from the evil organization Demon Card, forcing him to transfer the power of Rave to Haru. With the fate of humankind resting on his shoulders, the new Rave Master begins his quest to find the scattered Rave fragments.
