It begins in the year 0015 when a force known as the "mother," Sinclaire, threatens the world. Shiba, the first Rave Master attempted to destroy it with his sword. The resulting explosion, "Overdrive", destroyed 1/10 of the known world, and at the time it was largely unexplored. The "RAVE", named after its creator, Resha Valentine, using the first and last letters of her first and last name. It was shattered in Overdrive, dividing Rave into five pieces and all pieces but one were scattered across the world. However, Shiba was unable to destroy the Sinclaire, and only succeeded in damaging it.
Fifty years later, Haru Glory, a teenager living on the peaceful Garage Island discovers a strange creature. He encounters Shiba, who tells Haru it's called "Plue". Shiba explains that Plue is actually his companion and a Rave Warrior. Soon, Feber, a member of Demon Card, an organization attempting to use the Dark Bring to take over the world, finds Shiba and demands he hand over the Rave. Shiba hands Haru the Rave and tells him to run away, but Haru refuses and tries to help. With Rave clutched in his fist, he punches Feber. To everyone's surprise, Haru manages to unleash the Rave's power with this punch, defeating Feber with an explosion. Seeing this, Shiba realizes that Haru has been chosen by the Rave to become the second generation Rave Master. Thus begins Haru's search for the other pieces of Rave and his quest to defeat the Demon Card.
