In a bygone era, warriors wielding the holy Rave stones clashed with malevolent Dark Bring, culminating in the cataclysmic 'Overdrive' that subdued the Dark Bring and fragmented the Rave stones worldwide. Fast forward to the present, where Haru Glory resides tranquilly on Garage Island until he hooks the peculiar creature Plue while fishing. Recognized by Shiba Roses, the elderly Rave Master, Plue's presence heralds the resurgence of Dark Bring. Shiba entrusts Haru with the task of reuniting the scattered Rave pieces to thwart this looming threat. However, before Shiba can embark on this crucial mission, a Demon Card soldier's assault compels him to pass on the Rave's power to Haru. With the future of humanity hanging in the balance, Haru, the new Rave Master, sets out on a perilous journey to reclaim the dispersed Rave fragments.
