Fairy Tail: Gekitou! Madoushi Kessen/Lullaby

The quest begins when Lucy meets two other Fairy Tail wizards: Gray Fullbuster, an ice wizard who constantly bickers with Natsu, and Erza Scarlet, a powerful S-class Mage and one of the few who hold that honor in the guild. Erza asks Natsu and Gray to form a team with her in an effort to tackle a potentially difficult mission. Natsu is reluctant to join, until Erza makes a deal with him: after successfully completing the mission, she will face him in battle. With that, the team (and Lucy) head to the train station. This mission concerns a dangerous magical item, Lullaby, and a dark guild that plans to make use of it, Eisenwald. It isn’t long before Natsu runs into the mastermind behind the entire conspiracy: Erigor, assassin of Eisenwald.

Despite Erigor’s defeat, the team must now face a larger threat: the monster at the center of Erigor’s master plan, Lullaby.

Following the successful mission, Natsu hasn’t forgotten about the promise Erza made to him. Back at the train station, Natsu and Erza clash in the ultimate test of strength.

Back at the guild, Lucy notices the presence of two S-Class Mages: Mystogan and Laxus. She also learns of S-Class Jobs, placed on the second floor where only S-Class Mages have permission to enter. With that, the chapter concludes.
