Fairy Tail S03E33 - Turbulent Showdown! Natsu vs. Laxus

Natsu and Gajeel challenge Laxus to a duel. The guild and the town of Magnolia immediately organise an entire festival around the event, since it has been seven years something noteworthy like that has happened. Even though Natsu and Gajeel have increased in power since their last encounter with Laxus, it might not be enough to defeat the former S-Class Fairy Tail wizard.
