As the ancient city of Nirvana continues its path towards Cait Shelter, Natsu and Happy take a pounding from Cobra's poisonous strikes. But the power of a true dragon slayer should never be underestimated - as long as Happy can keep him off the ground!

There's still one Oracion Seis member left standing, and Nirvana doesn't show any signs of stopping! They have to defeat Midnight and a talking staff! Erza and Jellal try their hand at cracking the sorcerer's mirror magic, but things get ugly quick.
