Blue Skull is the 6th chapter of Fairy Tail Zerø, a prequel to Hiro Mashima's Fairy Tail. Shocked at seeing the desolation of Magnolia and the imposing Blue Skull Dragon Skeleton, Precht's group are greeted by an old man who tells them the city's situation. Suddenly, he is brutally murdered by some Blue Skull grunts who try to attack the group, but are effortlessly defeated, only for reinforcements to arrive. Mavis tries to intimidate them using illusions, but these are easily dispelled by the opponents' Guild Master and the Blue Skull members begin to overpower the group with their Magic and sheer numbers. Routed, the Treasure Hunters, Mavis and Zera are forced to flee into the forest with severe injuries.
