Rave Master, Volume 29 — Hiro Mashima

Haru and friends make their way through a trap-filled dungeon in order to reach the tomb of the Knights of the Blue Sky, where the final Rave Stone rests in the care of the last remaining Knight. But to get it, Haru will have to face a final trial--a fight against Shiba, the previous Rave Master. This ultimate battle between Rave Masters can only end when one of them pays the ultimate price!
