Within the tenth-floor boss room of the Sazardon Labyrinth, the mighty minotaur awakens once more. Unlike its predecessors, slain at the hands of treasure-seeking adventurers, this monster's primal urges push it further than ever before. Kill. Consume. Grow stronger. The more powerful its opponent, the more powerful it becomes. Even the very rules of the labyrinth seem to bend to its indomitable will. Can none triumph against this bovine behemoth? Will the minotaur ever meet its match...? (Source: Yen Press)
