Determined to get it back to it's former glory, they take on any job that comes their way-no matter how ridiculous. But nothing ever stays simple for the wizards of Fairy Tail.

Determined to find the remaining pieces, Natsu and his friends begin the search. But a secret order of wizards stands in their way, untrusting of the notoriously destructive guild. More trouble awaits them when Oración Seis is reborn in a terrifyingly powerful new form and wants the catastrophic clock for themselves!
