Fairy Tail (2009)

Season 4: Episode 16

Confronted by the Sabertooth Guild Master himself, Jiemma, Natsu decides to fight him all-out in their lodgings. Despite his attacks, he is unable to deal even a scratch on him. Eventually, their "fight" is interrupted with the arrival of Minerva and her hostage, Happy, forcing Natsu to leave reluctantly. The following day, the Grand Magic Games resume with a new event: Pandemonium. However, the beasts within the domain of this event appear to be quite challenging for the participants.
