Sixteen-year-old Haru Glory has never left the cozy confines of Garage Island. He likes fishing and eating snowcones on the beach -- not exactly the lifestyle of a hero-in-the-making. Meanwhile, in the wider world, the evil society Demon Card is threatening civilization as we know it. When they come to Garage Island, unleash the destructive power of the Dark Bring and start messing with his friends, Haru is forced into action. With the help of a transforming sword and his magical guide Plue, Haru sets out on the most harrowing quest of his young live: to find the five missing RAVE Stones -- which hold the key to victory over the Dark Bring -- and to kick some major Demon Card butt.
