Kageyama uses his Shadow Magic and knocks Natsu across the train car. Natsu starts to use his Fire Dragon Slayer Magic, but gets sick. He kicks Natsu in the face and says that they call the registered guild members 'flies'. On the train, Natsu is feeling sick from the moving vehicle when he is approached by an Eisenwald member, Kageyama. They reach Onibus Town and they suddenly realize they forgot to get Natsu off the train.

Erza plans to head straight into Eisenwald, but since she feels that she cannot take on a whole guild by herself, she asked for the others' assistance. They are to face off against another Dark Guild, Eisenwald, that is planning something evil with an item called Lullaby and they must stop them.

She then tells the others about the mission and how she came to know it from overhearing the name ' Erigor' and overhearing the discussion of Eisenwald members. Once they are aboard the train, Erza punches the motion-sick Natsu to knock him out and make the trip easier for him. 'Shinigami' Erigor, ace of Eisenwald as discussed by Erza Lucy also comes along at the insistence of Mirajane to keep Natsu and Gray from fighting all the time. They agree in order to stay in her good graces. Erza asks Natsu and Gray to help her on the next mission.

It seems it's because Erza is one of the strongest Fairy Tail Mages and has beaten both Natsu and Gray to a pulp before. Lucy is surprised by the sudden change in the atmosphere caused by Erza's presence. However, Erza Scarlet arrives in the guild, causing Natsu and Gray to start acting buddy-buddy all of a sudden as well as shocking the rest of the guild into propriety. While Natsu and Lucy talk about getting a job as a team, Natsu ends up arguing with Gray Fullbuster. Mirajane adds that there were Dark Guilds that don’t adhere to the rules and regulations of the regular guilds and they are often involved with criminal activities. Mirajane explains to Lucy the way the guilds work and the leadership breakdown from the Magic Council to the Guild Master League when Lucy asks about the regular meeting Makarov had gone to. Natsu Dragneel, Lucy Heartfilia, and many of the other members of the Fairy Tail Guild need money, and are looking over the job board.
