Makarov, master of Fairy Tail, is away at a meeting of local guild masters. Meanwhile, members of the dark guild, Eisenwald, have taken over a train as part of a plot. Its up to Erza, Natsu, Grey, Lucy and Happy to find out what they are planning and stop them. They catch up to the guild at Oshibana station where they reveal their plan to use the speakers in the station to broadcast the Lullaby, a Death Magic flute that kills all who hear it, to the surrounding city. Eisenwald's guild master runs off and Natsu and Grey are sent to stop him. Erza and Lucy defeat the rest of the guild with little difficulty. However, there seems to be more of Eisenwald's plan than originally revealed.
