Rave Master

Fifty years ago, a disaster called the "Overdrive" wiped out a tenth of the world, caused by evil stones known as Dark Brings. Now, a dangerous group called Demon Card is hunting these stones for their own twisted purposes. Haru Glory, a silver-haired teen skilled with a sword, becomes the next Rave Master - the one who can wield the Rave Stones, the only force strong enough to destroy the Dark Brings. But after the Overdrive, the Rave Stones were lost across the world, leaving Demon Card free to pursue their dark schemes.
