Rave Master 4

Things haven't been too easy for the new Rave Master, Haru Glory, since leaving his home to search for the missing Rave stones. He and his companions, Elie and Plue, have been forced into one battle after another as they flee from the sinister forces of Demon Card. Now they're off for Tremolo Mountain, where a shooting star is said to have fallen 50 years ago. Could it actually be a Rave Stone? Shuda, the Demon Card general, seems to think so; he's already got a team searching for it. To find the stone, Haru and Elie must go undercover into the Enemy's Mine. Hiding from the Demon Card minions is tough enough, but when Haru learns a ruthless assassin is already on his trail, he must prepare for the battle of his life.
