In the present day, the nefarious organization Demon Card seeks the Dark Brings' power for their all but innocent intentions. Haru Glory, a sword-wielding silver-haired teenager, inherits the title of Rave Master: the person who wields the power of the legendary Rave Stones, artifacts capable of destroying the Dark Brings.
