CHAPTER FOUR: EISENWALD

Back at the guild, everyone is doing their usual routines on a normal day. As always, Wakaba asks Mira on a date but she always reminds him using her Transformation Magic. Cana complains about wanting to drink in peace and Macao tells her that she drinks too much. Natsu rests his chin on the table wanting to go on a job and Happy reminds him that they're running low on money which makes Lucy complain about not taking the two million Jewel reward. Lucy goes to the request board to look for a mission and Mira tells her that she needs to know if she's going on a job because the Master is at a meeting. Lucy questions about the conference. Mira explains about how a conference between guilds work. Natsu jump scares Lucy making her angry at him. Mira also explains the dark guilds getting involved in crimes. Natsu gets bored of it, asking Lucy to pick a job.

"Just choose a job, will you?" Natsu said, smiling at Lucy.

"And what gives you the right to say that to me?" Lucy glared at Natsu.

"Well, we are a team and all." Natsu reminded her.

"We picked the job last time. This time it's your turn." Happy said.

"Yeah, right! You know our 'team' is disbanded." Lucy crosses her arms as she looks away. "You didn't care about me! You just needed someone with blonde hair!" Lucy remembers about the Everlue mission.

"That's not the only reason we chose you, Lucy." Natsu gives her a toothy grin. "It was because you're nice!" Lucy blushes a bit.

"Don't worry about picking a team; I'm sure you'll get a ton of offers soon enough." Aira said.

"You're annoying." Natsu muttered. Aira gives him a death glare. They clash their heads together, arguing with each other.

"Did you just call me annoying, fire freak?!" Aira growled at him.

"You're super annoying, water breath!" Natsu growled back. They continue to insult each other.

"There they go again." Happy and Cain said in unison.

"Lucy. Won't you form a team of love with me?" Loke flirts with Lucy, wrapping his arms around her neck. "Tonight, just the two of us." Lucy looks at him in confusion. "You really are beautiful." Loke pushes his glasses up. "Even with my sunglasses on, your beauty is dazzling. I'm sure I would go blind if I saw you with my naked eyes."

"Go blind. Fine by me." Lucy gets annoyed easily, not impressed by him. Her Celestial Spirit keys shine as she moved. Loke notices her keys shining and freaks out a bit.

"Y-You're a celestial wizard?!" Loke jumps back while Lucy looks at him weird.

"Yeah. She has a cow and crab and stuff." Happy comes in the picture with a fish in his mouth.

"What a cruel twist of fate." Loke screamed out loud. "I'm sorry! We can never be together!" Loke runs out of the guild, leaving Lucy behind.

"What's his deal?" Lucy asks Mira.

"Loke's bad at dealing with celestial wizards." Mira smiles at Lucy. "Rumor has it he had trouble with a girl a long time ago."

"I'm not surprised, he's-" Lucy gets interrupted when Natsu crashes into her. Natsu lies on her back as she gets irritated with the Dragon Slayers. "Knock it off, you guys..."

"He picked a fight with me. I can't turn down his offer." Aira said, holding his fist in the air.

"You're the one who started it, blue freak!" Natsu gets up and insults him.

"When exactly did I start it, pink bastard?!" Aira insulted back.

"Talk about petty..." Lucy sweat drops at them.

"They're always like this." Happy commented with Cain nodding in agreeement. The guild mates laugh at the Dragon Slayers, as well as Lucy.

Loke comes back into the guild with a warning ahead of them. "This is bad!" Everyone turns their attention towards Loke. "It's Erza... She's back!" Everyone sits there in utter shock when they heard Loke's warning. Natsu and Aira stop fighting and let go of their scarves.

"Erza? You mean the person Natsu mentioned earlier?" Lucy asked.

"You could say she's the strongest female wizard in Fairy Tail now." Mira responded. A shadow of a woman carrying a giant horn over her head walks towards the Fairy Tail guild, loud footsteps are heard right outside the guild.

"It's Erza." Laki stated as they sit in silence.

"Those are Erza's footsteps." Wakaba said, hearing her loud footsteps.

"Erza's come back..." Macao muttered. Lucy watches the entrance of the guild while the guild mates are muttering things under their breaths to each other.

"Given this reaction, Erza must be one powerful wizard...!" Lucy remembered about picturing Erza as a scary monster. "Scary!" The shadow of Erza with a giant horn over her head walks in the guild as people stare at her. Erza sets down the horn, making a loud noise.

"I've returned. Is the master here?" Erza asked.

"S-So pretty...!" Lucy admired her beauty. She looks nothing compared about what Natsu and Aira described.

"Welcome back!" Mira greeted. "The master's at a conference."

"I see." Erza replied.

"What is the humongous thing, Erza-san?" One of the guild mates asked.

"The horn of a monster I subdued. The locals decorated it and gave it to me as a souvenir." Erza answered. "Is it a problem?"

"No, not in the least!" The guild mate responded, terrified by her while everyone else gets nervous.

"I bet she's heard about what happened at Mt. Hakobe..." Cana said while drinking a barrel of booze.

"O-Oh, crap... I'm a goner..." Macao whispers to himself.

"She's not what I imagined at all..." Lucy muttered.

Erza turns to everyone, catching their attention. "Listen up! On the road, I heard that Fairy Tail has been causing yet more trouble. The master may not care, but I do!" Erza turns to someone else. "Cana! How dare you drink dressed like that! Vijeeter! Dance outside! Wakaba, I see cigarette buds on the floor. Nab. I see you dawdling in front of the request board as usual. Do some work! Gray, button up your shirt all the way! Macao!" Erza sighs at Macao.

"Say something!" Macao impatiently waits for her complaint.

"Honestly, you cause so much trouble." Erza shakes her head. "But I'll be kind and say nothing for today."

"She's already said a lot, though..." Lucy whispers to Mira. "What is she, a disciplinarian?"

"That's Erza for you." Happy said.

"Still, even if she is kind of a loudmouth, she looks like an actually-mature person." Lucy said. "Surely there's no reason to be afraid of her..?"

"Are Natsu and Aira here?" Erza asked, looking around.

"Aye!" Both Happy and Cain point to their partners. Natsu and Aira have their arms around their necks, acting like best friends as Erza watches them.

"H-Hi, Erza. We're good buddies as usual...!" Aira nervously replied. Natsu replies with a simple "Aye".

"Natsu's turned into Happy!" Lucy pointed out.

"I see. It's natural for good friends to fight sometimes, too." Erza crosses her arms, relived to see Natsu and Aira getting along for once. "That said, I like seeing you get along like that."

"No, we're not exactly 'good friends'..." Aira commented.

"Aye." Natsu added.

"I've never seen Natsu like this before!" Lucy is surprised to see Natsu acting maturely for once.

"A long time ago, Natsu challenged Erza to a fight and got really beat up." Mira informs Lucy.

"She found Aira trying to drown Natsu with his magic during one of their fights and beat him up." Macao mentioned.

"She beat Loke up too for trying to hit on her." Cana added. "You reap what you sow."

"I would've expected as much from him..." Lucy muttered.

"Natsu. Aira. I have a favor to ask." Erza said. Natsu and Aira look at her in shock. "I heard about something bad while on my last job. Normally, I would consult the master about something like this first, but I believe this is a matter of the utmost urgency. I want your help. Will you come with me?" Natsu and Aira look at each other.

"What in the world?" Guild mates whisper to each other. "Erza's asking for help?" Surprised that Erza asking for help for the first time. "This is a first!"

"We leave tomorrow. Make sure you're ready." Erza informed them.

"Me and him..." Natsu thinks to himself.

"...on a team?!" Aira thinks to himself as well.

"Erza, Natsu, and Aira... I never imagined it before..." Mira muttered. "But this could very well be the most powerful team in Fairy Tail..."


The Next Day...

The four Mages including Happy and Cain, go to Magnolia Station to take on the mission that Erza needed help with.

"Why do I have to team up with?!" Natsu angrily yells at Aira.

"That's my line! If Erza needs help, I'm more than enough by myself!" Aira shouts back. Aira is wearing his usual light blue scarf, a dark blue overcoat with a black shirt underneath, gray pants, and black boots.

"Then go by yourself! I don't wanna go!" Natsu keeps on complaining.

"Don't come, then! Let Erza beat you senseless later!" Aira complains as well. Everyone stares at the Dragon Slayers who are arguing in the middle of the station.

"I don't know them. I don't know them." Lucy gets embarassed by them and sits on a bench with Plue sitting on her lap while Happy is eating a fish and Cain just sighs at his partner who was fighting with Natsu.

"Why are you here, Lucy?" Happy asked.

"It's because of Mira-san..." Lucy replied.

Past...

"Those two will fight when Erza's not looking, so be there to stop them, okay?" Mira innocently smiles at Lucy.

"Me?!" Lucy sits there in surprise, becoming responsible for the Dragon Slayers.

Present...

"You aren't stopping them, though." Happy pointed out.

"I know, but..." Lucy whined.

"I'm sorry. Did I keep you waiting?" Erza comes to the station with a huge stack of luggage. The Dragon Slayers instantly stop arguing, behaving themselves.

"So much luggage!" Lucy stares at it in shock.

"Let's be good buddies today, as usual!" Aira and Natsu wrap their arms around their necks, looking like a pair of good friends.

"Aye, sir!" Natsu cheers on.

"Yes. It's important to be on good terms." Erza said. "So, who are you? Didn't I see you at Fairy Tail yesterday?" Erza asked Lucy as Natsu and Aira jump around. As Erza turns her back to them, they clash their heads together and continue to argue.

"I-I'm Lucy! I just joined!" Lucy happily introduces herself, carrying Plue in her arms. "Mira-san asked me to come with you too. It's nice to meet you!"

"I'm Erza. It's a pleasure." Erza introduced herself. "Ah, so you're Lucy?" Erza glances at the Dragon Slayers, they quickly stop fighting and act like best friends. She turns bacxk to Lucy, Natsu and Aira start fighting again. "The one who defeated a mercenary gorilla with just your little finger?" Lucy jumps in utter shock. "It'll be wonderful to have you on board. Thanks for your help." She takes another glance at the guys.

"M-My pleasure..." Lucy sweat drops at her. In her mind she thinks of a different situation.

"Erza. I'll come along, but on one condition." Natsu seriously said. Aira warns him not to do it.

"What is it? Tell me." Erza looks back at Natsu.

Natsu clenches his fist up to his face. "Fight me once we get back!"

"Hey! Don't get hasty! Do you want to die?!" Aira puts his hand on Natsu's shoulder.

"Things are different from last time." Natsu evilly grins at him. "I can beat you now!"

Erza smirks at Natsu, accepting his request. "It's true that you've improved. I feel somewhat at a disadvantage, but all right. I accept."

"All right! Now I'm fired up!" Natsu yelled as he clenches both of his fists, lighting his head on fire.

They aboard the train, waiting to arrive at their destination. Natsu gets motion sickness, almost passing out.

"Geez, you're pathetic. This, immediately after picking a fight? It's a good thing I drank water before we came, otherwise I'd be in the same boat." Aira rested his elbow near the window, staring at the outside.

"It's gotta be tough doing this every time..." Lucy felt bad for Natsu.

"Oh, all right. Come sit next to me." Erza said.

"Is she telling me to move?" Lucy gives her a straight face.

"Just relax." Erza puts her arms around Natsu. She delivers a hard punch to Natsu's guts, knocking him out as he lands on her lap. "There. That should be better."

"Th-This woman might be a little weird after all..." Lucy thinks to herself.

"Erza. Isn't about time you fill us in?" Aira asked. "What exactly are we doing?"

"Right. We're going up against the Eisenwald dark guild." Erza answered. "They plan to use magic called Lullaby for something big."

"Lullaby?" Aira and Happy questioned.

"That thing from before?!" Lucy asked.

"I see. So you've encountered Eisenwald as well." Erza said.

"Probably. They mention something about Lullaby." Aira stated.

"It sounds like they were guild dropouts." Erza commented. "The plan must've been too much for them, so they ran off."

"And that plan has something to do with Lullaby?" Aira asked.

"It's only a guess, but the shadow that dragged them off was probably Eisenwald's main squad." Erza answered. "They must have not wanted the plan to get out."

"What kind of plan are we talking about?" Lucy questioned.

"Allow me to explain everything in order. It happened the other day on my way home after that job. I stopped by a pub in Onibas where wizards gather." Erza explained. While she was in Onibas, in a bar, she overheard a group of wizards talking about Lullaby's location.

"Lullaby... Like a nursery rhyme, right?" Lucy asked.

"Yes. The fact that it's sealed away likely means it's powerful magic." Erza replied.

"And they were members of Eisenwald too?" Aira asked.

"Yes. Like a fool, though, I didn't recognize the name 'Erigor' at the time." Erza said. "He's the ace of the Eisenwald dark guild. He only accepts assassination-related jobs, for which he earned the nickname "Erigor the Reaper."

"Assassination?!" Lucy said.

"The council outlawed assassination requests, but Eisenwald decided that money is more important. As a result, it was kicked out of the wizard guild league six years ago. However, they disobeyed orders and remain active to this day." Erza explained.

"I think maybe I'll go home." Lucy nervously sweats. Erza slams her fist on the side of Natsu's head.

"I was careless! If only I had recognized Erigor's name then, I could've pulverized them and had them confess their scheme!" Erza angrily said.

"I see. So Eisenwald is planning to do something with this Lullaby, and you want to stop them because it's obviously something bad?" Aira asked.

"I don't believe I can take on an entire guild by myself. That's why I asked for your help." Erza said. "We're going to storm the Eisenwald guild!"

"Sounds interesting." Aira smirked.

"I shouldn't have come..." Lucy commented. The train stops at a train station for other people to aboard. "If it's not rude to ask what kind of magic do you use, Erza?"

"It's not rude." Erza replied.

"Erza's magic is pretty! It makes her enemies bleed a lot!" Happy said.

"You call that pretty?" Lucy commented.

"Personally, I think Aira's magic is prettier even though it's similar to Natsu's." Erza takes a bite of her strawberry cheesecake.

"Really?" Aira uses his Water Magic to make streams of water come from his finger. Lucy admires his magic. "I'm the Water Dragon Slayer."

"Oh! Is that why you and Natsu never get along? Because Natsu uses fire and you use water?" Lucy asked, making a point.

"Oh, I never thought of that." Erza commented.

"Does it matter?" Aira sweat drops at them.


The train finally arrives at Onibas Station. "Are the Eisenwald guys still in this town?" Aira asked.

"I don't know. That's what we're about to find out." Erza replied.

"That's going to be a wild goose chase..." Lucy commented.

"Huh? Where's Natsu?" Happy asked. Natsu is left behind on the train as it leaves. "There it goes." Happy waves the train goodbye while Lucy drops her luggage with a wide open mouth.

"I was so absorbed in our conversation that I forgot. I can't believe myself. He's terrible at riding vehicles, too!" Erza clenches her fist and blames herself for leaving one of her comrades behind. "This is my fault. Could you please hit me?!" Lucy tries to calm her down.


On the train, Natsu is feeling sick from the moving vehicle when he is approached by an Eisenwald member, Kageyama. He kicks Natsu in the face and says that they called the registered guild members "flies". Natsu starts to use his Fire Dragon Slayer Magic, but gets sick. Kageyama uses his Shadow Magic and knocks Natsu across the train car.

The train suddenly stops due to the fact that Erza pulls the emergency stop back at the station so they can catch up to the train.

"Now that it stopped moving, Natsu gets up and sees a strange looking flute that has a skull on top with three eyes. Kageyama looks panicked because Natsu saw the flute and then he defends himself against Natsu's attack. Suddenly, the conductor announces that the stop was a false alarm. At first, Natsu wants to take the battle outside. But when the train starts to move again, he jumps out and just happens to hit heads with Aira as Erza drives their Magic-Four Wheeler to catch up to the train.

"That hurt, you idiot!" Aira yelled.

"Shut up! How dare you leave me behind!" Natsu yells back in anger.

"My apologises. But you don't appear hurt. I'm glad." Erza grabs Natsu's head and slams it on her armor.

"That's hard!" Natsu felt the pain from her hard armor. "Urgh! I'm not all right! Some weirdo attacked me on the train!" Lucy questions him about a weirdo. "The one who dragged away the guys who tried to eat Happy. Said he was with Eisenwald..."

Erza immediately slaps Natsu across the face. "You fool! We're trying to go after Eisenwald! Why did you let him go?!"

"This is the first I've heard of this..." Natsu holds his cheek while he looks up at Erza in confusion.

"I explained it earlier! Listen when people talk!" Erza scolded him.

"I think it was because you knocked him out... She's unbelievable in various ways..." Lucy commented. Aira agrees with her while Happy reminds her that's just how Erza is.

Erza gets back on the vehicle and wraps the SE plug around her wrist. "He was on the train, you say? We're going after it!"

"What was he like?" Aira asked.

"He wasn't very distinctive, actually. Oh, yeah. He did have some sort of skull flute. The skull had three eyes." Natsu tries to remember.

"A three-eyed skull?" Lucy asked.

"That's creepy." Aira commented.

"What's the matter, Lucy?" Happy worriedly asked.

"I know about that flute... Lullaby... A cursed song...! It's death magic!" Lucy exclaimed.

"A cursed song? Like an incantation?" Aira asked.

"I've only read them about them in books, but there are some deadly, forbidden spells out there, right?" Lucy said.

"Yes. Cursed black magic that kills whomever its used on." Erza commented.

"Well, Lullaby is even worse than that." Lucy warned.


The citizens scream in horror when they see a man with a large scythe murder an official who worked at the station. The man, who happens to be Erigor, orders his men to empty the train and kill anyone who dares question them. The dark guild, Eisenwald, claims the train from Kungui Station as their property. Kageyama informs Erigor that he knows a way to break the seal on Lullaby.


Erza harshly steps on the gas of the Magic Four-Wheeler, rushing towards Eisenwald. "Slow down, Erza! Powering this thing takes up a lot of magic energy! Even for you, Erza!" Aira warns her.

"This is no time for complacency!" Erza shouted. "There's no telling what Erigor might do if he gets his hands on this death curse magic!" Inside the vehicle, Natsu gets sick once more. "Curse them... What is their aim?!" Erza thinks to herself while driving to the station where Eisenwald is at.


A/N: In case you haven't realized, water is a common element. Therefore, if Aira drinks his element, he doesn't get motion sickness. Kinda like Wendy's spell "Troia" (Idk if I spelled it right)

Just thought I would clear that up.

Hope you enjoyed!
