Diablo and the others were heading to the dungeon to obtain the hidden treasure that can cure the Death Knell Disease when Laminitus and her army surrounds them and attacks. Their party manages to reach the entrance to the dungeon, but there are now six marks on Lumachina's body, and it's said the victims of the Death Knell Disease will die once there are nine marks...
