FAIRY TAIL Vol 31

From the Kodansha edition

BACK TO SQUARE ONE! Seven years have passed, and without its most powerful wizards Fairy Tail has become the laughingstock of the magical world! Even after returning, Natsu, Erza, Makarov and the others quickly realize that restoring Fairy Tail's good name will be tougher than they imagined. New and far more powerful guilds have arisen, and the upcoming Grand Magic Games might be Fairy Tail's only chance at redemption. But how do you make up for seven years away in just a few days?
