Chapter 6: Eisenwald

Dragneel Household

It was early in the morning, the sun has just rise and majority of the population in Magnolia Town were still sleeping, it was very quiet on the streets but that was not the case in Dragneel Household, in the basement of the mansion, there was a huge training ground that seemed endless, it had some trees and a hot spring. In the middle of the training ground sounds of fighting could be heard as two blurs were darting from one place to another, if one were to see the state of the training ground they would think that a war has been fought here since there were numerous craters and various trees were toppled down. When they two figures separated from each other, we could see a heavily panting Mira and a lightly panting Natsu, they both have been training for past two hours non-stop.

"You have gotten stronger Mira," Natsu commented.

"Yes but I still can't effectively land a hit on you," Mira pouted.

"Its only a matter of time before you do that, you are already as strong as I was after I started training with Gildarts," Natsu said as both of them left the training ground to get ready for the day.

After they had gotten ready and ate breakfast both of them made their way to the guild. When they both arrived at the guild, they noticed that not many people have arrived to the guild. After about two hours later, every guild member strated arriving at the guild hall and it wasn't long before a guild brawl took place but that all stopped when suddenly the doors of the guild hall busted open and a heavily panting Loke had a look of horror on his face, "Guys it's bad, she is back, Erza is back!" he shouted and the next moment was completely chaotic, every member save for Mira, Natsu, Happy and Lucy, who had a confused look on her face, was running around in panic like headless chicken.

"Shit! I better get out of here!" Gray run to the door. Not wanting to be with Erza at the moment.

"Who is Erza?" Lucy asked.

"Erza is the second strongest female in the guild after Mira," Happy replied to her, "And you don't stand a chance against her, Luigi!" he added last part cheerfully.

"Its Lucy you damn cat," Lucy shouted as she started chasing the Happy, "Get back here stupid feline so that I can skin you alive!"

"Natsu, Mira help Lucy is trying to kill me," the blue feline said as he hid behind Mira.

"Happy you shouldn't tease people like that," Mira scolded him as everyone waited, holding their breaths, for Erza to arrive. They heard the sound of heavy pounding, like somekind of monster was walking toward the guild hall, making Lucy feel uncomfortable at sight of the looks of normally happy guild members turn into completely frightened ones.

Suddenly a beautiful red head came into the guild hall holding a giant horn of somekind, "I'm back," she announced, "Where is the master?" she asked.

"Welcome back Erza," Mira greeted her, "Master went in a meeting," she informed her. Erza's expression turned stern and she glared at everyone present in the guild causing all of them save Mira, Natsu and Happy, to flinch in fright.

The silence was broken when a poor soul decided to speak, "Umm Erza, what is that huge thing?" asked a member named Max.

"Oh this," started Erza as she placed her palm on the horn, "The local townspeople decorated the horn of a demon I had defeated. They gave it to me a souvenir. Will it be a nuisance here?" she finished with a glare at his direction daring him to say Yes.

"Not at all!" all of terrified mages shouted even though she only adressed Max.

"You think she knows about the incident at Mount Hakobe." Cana teasingly wishpered to Macao who was sweating buckets.

"Oh man! I'm a dead meat." muttered Macao nervously making the bruentte giggle.

"She is quit different from what I imagined." Lucy wishpered as she gazed at Erza in awe. She was fascinated by the woman's beauty.

"All of you!" Erza suddenly exclaimed as she glared draggers at the mages making them sweat, "I heard some rumors during my absence. About how Fairy Tail keeps causing problems. Master might forgive you, but I will not!" she then began to scold them for their behaviours, "Cana! how dare you drink in such a shameful manner!"

"Bigitar! take the dancing outside!"

"Wakaba you're dropping ashes everywhere!"

"Nab! stop staring at the request board and pick up a damn job already!"

She then turned to Macao, "Macao!" she stared at him before letting a sigh.

"Say something!"

"Geez you're all so troublesome. Anyway, I won't say anything today." she said and pinched the bridge of her nose.

"She said quite a lot already." wishpered Lucy and turned to Happy, "Is she with the disciplinary committee or what?"

"That's Erza!" Happy said with a fish in his mouth.

"Anyway, is Gray here?" Erza asked Mira.

"H-H-Hey E-E-Erza!" stuttered the ice mage as he appeared in front of her. He wrapped his arm around Natsu's neck, "I-I'm getting along with N-Natsu! Like g-good friends!" he was clearly shaking in fear, Natsu decided not to say anything in that regard since he knew how merciless Erza can be when it comes to discipline even more so with him and Gray since she knew that both of them can take a heavy beating.

"Best friends fight from time to time." she stated with a smile, "But i'd like to see you getting along."

"B-best friend is a little..." Gray weakly protested.

"Why is Gray so scared of her?" asked the curious blonde.

"One day, she caught Gray walking completely naked and beat him within an inch of his life. Loke suffered the same fate when he tried to hit on her." answered Happy giggling at the memory.

Lucy gulped a little, this woman seemed scary! She would have to keep herself from upsetting or irritating Erza and Mira both.

"Natsu, Mira, Gray I need your help," Erza said shocking everyone, "Normally I would have consulted master about something like this but since he is not here I don't have a choice and what I have overheard when I was on my way back from my last job request is troubling," she added, "So will you guys help me?" she asked.

All three of them dumbly nodded still processing what just transpired. "Great meet me at train station tomorrow at 8 in the morning," the red head said before she left the guild hall, leaving everyone stunned and a blonde female confused.

"W-W-What just happened?!" Gray asked.

"I-I believe that we just formed the strongest team in Fairy Tail," Mira said equally stunned.

Meanwhile there were muttering all over the guild.

"What's going on?!"

"This is the first time Erza teamed up with anyone from the guild!"

"Those four in a team?!"

"The world is ending!"

They were really being way too overdramatic...

"Lucy why don't you come with us? It might be a good experience for you!" Natsu said after he got over his shock.

Lucy thought over it for a moment, "Sure, who knows it might be fun!" she said excitedly.

Next Day

Natsu, Mira, Happy, Gray and Lucy were the first to show up at the train station.

Natsu, Gray and Lucy were in their usual outfit while Mira's was completely changed, Mira was wearing a black shirt with black tight pants, a pair of black steel-toed shoes, fingerless gloves on each hand similar to Natsu's and a with coat that reached her knees similar to Natus's but except for a Dragon, there was a Demon on the back of the coat.

Gray was shouting and glaring at Natsu while the latter was cleaning his ear with his pinky, having a bored expression on his face as they waited for the red head to arrive.

"Why do I have to be stuck with you?!" The ice mage shouted with a vein poping on his forehead, "If Erza wants help, I can handle that by myself!"

"If you don't want to go with me, then fine! Stay home and get beaten by Erza afterwards!" countered Natsu as he waved his arm at his friend.

"What did you say?!" Gray shouted as he rediated himself to use his magic.

"Gray I think that's enough, it is still too early in the morning for you to blow up your fuse," Mira said with a sweet smile, she had hands crossed over her bust and was radiating a menancing aura, causing Gray to gulp in fear.

"I-I-I'm sorry Mira, it won't happen again," Gray stuttered out and sat down on a bench waiting for the red head. It wasn't long before Erza arrived at the station pulling a massive cart full of luggage behind her, freaking Lucy out.

"Sorry did I made you wait?" she asked.

"No Erza, we haven't been here for long," Mira replied and the red head nodded.

"That's a lot of luggage!" she shouted with bulged eyes and dropped jaw.

"And you are? I think I saw in the guild yesterday."

Lucy began her introduction, "I'm the new recruit, Lucy. Nice to meet you." she finished with a bow.

"I am Erza. It's nice to make your acquaintance. So you are Lucy, you beat a Gorilla monster with one finger." Erza said with an impressed tone.

Lucy's sweat dropped, "Uhh... That was Gray, when we went on our mission."

"This mission will be a bit risky, but with your performance in the last mission. I am sure you'll be fine." Erza completely ignored Lucy's words.

"R-risky?!" the busty blonde shrieked.

"Anyway let's go, the train is about to leave." Erza said.

They all nodded and headed onto the train Natsu was sitting with Mira and Happy, and Gray was sitting with Erza and was until Gray decided to break it. After the train took off they all sat in silence as they left past the station.

"Erza, it's about time you told us what are we supposed to do." he said.

Erza nodded and began to explain, "Our opponents is the dark guild: Eisenwald. They intend to cause trouble with some magic called Lullaby." she informed them, everyone seemed confused by it except for Natsu and Mira who were having a mental conversation between them and Natsu's tenants.

"I can't believe that overgrown tree is still alive considering how weak it was," Igneel said to Mira and Natsu.

'Natsu what are we going to do about Lullaby!' the busty white haired mage asked.

'When the time comes I want to fight it alone, so make sure that everyone is out of the way.' Natsu replied to his wife who agreed with him and turned their attention back to the conversation.

"When did you get this information?" asked Gray.

"I will explain everything." Erza started as she recalled what she had heard, "It was on the way back on my last job. In the city of Onibas, I stopped at a bar where Mages gather..."

Flashback

Erza was seated at a table near the bar drinking quitely. She just finished the mission and it was boring for her taste. She was snapped out of her train of thoughts when she heard some yelling from a nearby table.

"Hey! Where is my booze?!" a voice echoed through the bar and even people outside could hear re-quip wizard turned her head and saw four people seating on a table, the one who yelled seemed to have whiskers on his face. he had a great resemblance to a rat.

"Hey calm down!" one of his companion told him as he leaned back into his chair.

"How can I calm down?!" he shouted as he slammed his empty mug on the table, "We finally found where Lullaby is hidden, but that damn seal is an obstacle!"

"You talk too loud!" a hooded man shouted at him.

"No need to rush." a man with black hair said, "I will take care of the rest, you guys can retuen to the guild. Tell Erigor that I will be back with Lullaby in three days!" he stood up and smiled at them.

Flashback End

"What the hell is this Lullaby?" Gray asked with confusion laced in his voice while both Natsu and Mira decided not to say anything just yet.

"I don't know. But it has been sealed, so it must be a very powerful magic." Erza replied

"So those guys were part of Eisenwald." said the ice mage seriously.

"Yes. I didn't realize it at first. Until I remembered the name Erigor, Eisenwald's ace. He is called 'Reaper' because he only accept assasination requests." Erza's eyes hardened like steel as she spoke.

"Reaper?!" Lucy asked in panic as she began to sweat buckets.

"Luigi! your juice are leaking out!" Happy chirped.

"It's sweat and I am Lucy you damn cat!"

"So in short, Eisenwald plan something really bad with this 'Lullaby' and that's why you want to stop them." Gray concluded as he locked eyes with the red head.

"Yes! I didn't think I would be able to beat an entire dark guild by myself. That's why I asked for your, Mira and Natsu's help," said the knight.

"Sounds interesting!" declared Gray with an excited smile, "But don't you guys know what is this Lullaby?"

"I know what is Lullaby."

Everyone turned their eyes to Natsu who spoke. His face was completely serious.

"Lullaby is a Living Magic spell and one of the creation of that cretain Black Wizard." spoke the Dragon Slayer as his eyes briefly turned dragon-like when he mentioned Zeref.

"The Black Wizard?!" asked a shocked Lucy.

"You mean one of Zeref's demons?!" Gray asked throught gritted teeth as he remembered Deliora.

"Do you know more about it, Natsu?" Erza asked. This were more dangerous than she initialy thought.

"It's an Etherious. Also known as Mass Murder Curse Magic that is capable of putting a death curse on everyone who hears its melody except for the Caster." it was Mira who explained about Lullaby as both her and Natsu had done research over all of Zeref's demons.

"I've read about it in books! It's Black Magic!" Lucy added her two cents. She was now trembling from fear.

"Right. A Black Magic curse that saps the life out of the person it's cast upon." Mira said as she recalled one of the books she had read about Black Magic.

Erza gritted her teeth in self-anger, "If I had remembered the name Erigor, I would have beaten up those mages so hard until they told me about their plans!" she said with clenched fists.

"S-scary..." Lucy sttutered in fear while Gray and others sweat-dropped at her.

Natsu laughed a little, there were somethings that never change and one of them just heppened to be Erza's personality especially her temper. "No need to beat yourself over this Erza. Lullaby is one of the weakest, if not the weakest of Zeref's demons out there, just one of us will be enough to destroy it." Natsu's words relieved everyone. He continued talking but with a more excited tone, "Now we have to focus on pulverising that sorry excuse for a Guild!"

"Yeah!" they shouted enthusiastically.

Later

"By the way, what kind of magic do you use Erza, Mirajane?" Lucy asked curiously.

"Erza and Mira's Magics are so pretty! Erza's magic make her opponents's blood squirt everywhere! And Mira can transform into really pretty looking Demons!" Happy chirped cheerfully as he munched on another fish. It looked like he had an infinite appetite for fish.

Lucy turned blue and a huge sweat-dropped on her head, "T-that's pretty?"

"I use Requip Magic, it allows me to use different armors and weapons for any situation." Erza declared while eating her beloved Strawberry cake.

"I use Take-Over Magic and because of Natsu now I use use Dragon Slayer Magic." Mirajane followed with a proud smile, confusing Lucy, Erza and Gray about the last part.

"Personally, I think Gray's Magic is more prettier than mine." Erza said, still confused about the last part that the white haired beauty said, making said ice mage raise an eyebrow.

"You think?" he asked before putting his right fist on his left palm gaining Lucy's attention. Frost began to generate before he opened his fist showing an ice sculpture of Fairy Tail's mark, "It's Ice Magic."

"Waoh!" exclaimed Lucy in awe. Relization hit her then, "so that's why you and Natsu don't get along! Because Natsu use Fire and you use Ice!"

"Whatever!" Gray turned away making them chuckle at him.

"What about you Natsu?" Lucy turned to him.

"Hmm?"

"I didn't see your Dragon Slayer Magic since I joined. Can you show it to me?" she asked like an eager child who found a new toy.

Naruto sighed and held both of his palms out, he carefully manipulated the temperature of his flames to not hurt them or burn anything nearby in his right palm while he carefully manipulated the intensity of his lightning in his left palm. The other looked in fascination and awe as his right hand turned completely into orange fire and left hand turned into blue lightning. It was as if his hands become the fire and lightning themselves. They could feel the power, intensity and strength of both the fire and the lightning. He then brought both his hands together and merged both of his elements causing the blue lightning to dance over the orange flames, it was a sight to behold.

Others were looking at him with the same fascination that Lucy had been looking at, ever since Natsu has returned from his training trip, Makarov have forbidden him from using his Slayer Magic due to the strength behind it so they had not seen it since then, only Mira had seen it when he was training her in Slayer Magic, although they were confused about the lightning part. While Natsu was showing his magic to others Mira was doing the same thing as Natsu and all of them could feel the power, intensity and strength behind the magic, not as strong as Natsu's but still strong enough to defeat any of them.

"This is my pride and joy, I'm a Lightning-Flame Dragon Slayer," Natsu said, he decided not to say anything about his Lightning-Flame Demon Slayer Magic just yet, "Although I know some other magic as well like Crash Magic, Requip Magic, Wind Magic."

"Amazing!" Lucy breathed out, "What can it do?" asked the Celestial Spirit wizard wanting to know more of the magic.

"A lot." Natsu started as his mind wondered over all the developements that has come to his magic over the years, "I can burn and fry or electrify almost everything including magical attacks. Because of it, heat and cold or storms doesn't bother me." he let out some things as he didn't want to reveal his cards just yet.

Lucy stared at him with stars in her eyes freaking him out slightly. Maybe he said too much...

"Since when can you use lightning?!" Erza asked.

"I always had the lighting element just like my fire element but Igneel sealed my Lightning Dragon Slayer Magic and some of my Fire Dragon Slayer Magic away because my body was not strong enough to handle the strain from using two different elements or the full strength of my Fire Dragon Slayer Magic." Natsu said.

"The part that I find most confusing is that how can Mira use the same magic as Natsu?!" Gray wondered out loud.

"I can use same magic as him because of him being a Dragon Slayer," Mira replied.

Seeing that they were still confused Natsu decided to elaborate, "As you know, we Dragon Slayers take on the traits of dragons like their sense of smell, sense of hearing and many other things and one of them is that just like dragons we dragon slayers can fall in love only once in a lifetime no matter what. If our mates love us back, then we mark each other with dragon slayer mating mark indicating that both the slayer and their mate love each other. With mating marks comes several perks like we can talk telepathetically, we can sense each others emotions, we will always know where our mate is and if they are safe or not, our mate's magic power increases significantely, their aging process matches the dragon slayers', since we dragon slayers age slower than other humans after a certain age, their life force also increases to match ours, since we slayers live longer than average human, our mates gain our magic and both the slayer and their mates are fiercely loyal to each other and would do anything to protect each other," he informed to the group, they all looked surprised by the new information.

Later

When the train was near Onibus station and everyone prepared to get off the train, Natsu smelled something that wasn't in the train, 'Mira, I'm sensing Dark Magic right now and I'm also smelling death and blood, so I want you to get off the train with others and wait for my signal to stop the train, meanwhile I will check it out,' Natsu said telepathically to his wife.

'Alright but please be careful,' Mira replied to which Natsu nodded. When the train she and the others got off the train, while Natsu stayed on it. It wasn't long before the train left the station and a young man of average height and weight with black eyes and black hair which he tied in a short, spiky ponytail, came toward him.

"Excuse me. Is this seat taken?" he asked as pointed to the seat opposite of Natsu. Natsu said nothing just nodded his head as looked at the man in front of him.

'He reeks of death, definitely the same guy I've been smelling,' Natsu thought to himself. "Nope, go ahead," he grinned and gestured toward the seat.

"Thank you," the man sat down and looking out the window. "It is quite a nice day."

'Cut the Crap!' Natsu thought but kept himself in check, "Sure is."

The man's gaze then turned down to Natsu's guild mark, "Ah, so you're a member of Fairy Tail, huh?"

"Hmm…oh yeah, that I am," Natsu replied as he kept his fake grin up.

"I envy you, being in a normal guild and all. You legal guilds, acting all high and mighty because you think your status means you're worth a damn. You fools are nothing compared to me and my guild, Eisenwald!" He told him and Natsu had to suppress a smirk that threatened appear on his face, "And the thing that I envy most about your guild is that it has so many hot girls while we don't, especially that Mirajane woman, what I would give to have my way with her," he added lecherously.

Natsu hearing this snapped, a ginormous amount of pressure was felt by the man as temperature of the compartment starting rising and when he looked up at Natsu he nearly wet himself, instead of his normal eyes, they looked similar to that of a dragon as a visage of a huge red dragon appeared behind Natsu but everything came back to normal just as quickly as it happened. The man feeling what just happened and knowing that it was caused by the slayer sitting in front of him, launched a kick at Natsu, who caught it.

"You know…" He said before tightening his grip on the foot. He then bent it causing a pop, effectively breaking the man's ankle, he also noticed the Lullaby with the man's and he had to admit that it was a creepy looking flute that gave off an aura of death and it's three eyes just screamed danger and death. Before the man could even register the pain, Natsu had caught hm by his throat, lifting him from the ground, "Its people like you who kills for joy, that pisses me off but what you just said about my wife has made me really angry and now you are going to feel my wrath, the wrath of a Dragon," just as soon as he finished he smashed the Dark Mage into the ground causing him to cry in pain before grasping him by the ankle and throwing the guy to the other compartment. He was about to follow him but the train suddenly stopped, 'Damn it Mira, I told you to wait for my signal, I found a guy from Eisenwald guild,' he told her.

'It was Erza who did this, I told her and others about what you told me but she didn't listen and pulled the emergency breaks here on the station and now we are on our way to the train in a magic mobile,' Mira told informed. Naruto just sighed and went after the guy whom he just threw away but as he approached the place he noticed that his opponent was nowhere to be found, the other passengers were looking at him strangely and there was a hole on the side wall of the compartment, indicating that the dark mage had ran away from Natsu.

Natsu just sighed at that as he felt the train start moving again and felt his wife's presence near him, he approached the doors of the compartment and used Flash Step to meet his friends. He arrived just few meters away from the magic mobile and saw that Erza was driving the vehicle while Mira was glaring at her and Gray, Happy and Lucy were seating on the passenger seat. When they noticed Natsu, Erza quickly stopped the vehicle and all of got the magic mobile, they got near him and were about to talk to him but noticed the glare that he was giving them and decided to keep their mouth shut.

"Can any one of you tell me why did you stop the train when I asked Mira not to?" Natsu said while taking deep breaths to calm himself. It was Mira who explained everything to him.

Flashback

"Hey guys where is Natsu?" Lucy asked after not seeing Natsu with them.

"He stayed on the train because he was sensing death on the train and was also smelling a lot of blood, so that he can investigate it and make sure that everyone on the train is safe," Mira replied.

"What but why didn't he, or you for that matter, tell us, we could have helped him!" Erza said.

"You and I, we both know that Natsu doesn't need our help and if there is someone out there who can beat Natsu in a battle then how long do you think we will last," Mira argued.

"It doesn't matter, we are going to see if he need our help," Erza said as she made her way to the emergency breaks and pressed it in order to stop the train on which Natsu was riding.

"Damn it Erza, do you know how pissed Nasu is going to be now, he said that he would give me a signal to stop the train," Mira shouted as they made their way to the magic cycle that Erza had 'borrowed' just now.

'Damn it Mira, I told you to wait for my signal, I found a guy from Eisenwald guild,' she heard Natsu's voice and he sounded pissed.

'It was Erza who did this, I told her and others about what you told me but she didn't listen and pulled the emergency breaks here on the station and now we are on our way to the train in a magic mobile,' Mira replied, she felt Natsu had calm down a little she siged in relief.

Flashback End

"Do you know Erza that because of your impatience and lack of confidence in me, I lost the guy that I found was the source of the Dark Magic that I had been sensing for quite sometime on the train!" Natsu said causing Erza to look down, "And do you know that he was from the Eisenwald guild, I could have extracted some valuable information from him about their guild and their plans with the Lullaby, it's lucky for us that I am a Dragon Slayer and caught his scent otherwise we may have lost him." Natsu said and signaled everyone to get on the magic mobile and he himself sat on the driver's seat and started driving it and a fast speed in order to catch up with the guy he fought in the train.

Unknown Location

"What do you mean that he saw you and the Lullaby?" shouted a furious Erigor.

"It's just that he caught me off-guard and he was also stronger than me but that doesn't matter since he or any of those flies won't be able to find us on time or ever." Kageyama said while trembling a little.

"It doesn't matter if they find us not, you said it yourself that he was stronger than you, he could have caught you if the train hadn't stopped when it did," Erigor said furiously.

Sudenly all of the guild members heard a comotion outside of the place where they were staying, a member of their guild suddenly came running, "Erigor this is bad, it's the fairies, they have arrived and two of them are Natsu Dragneel and his wife Mirajane Dragneel," he said in a panicked tone.

"Oh so they have arrived and have the infamous Salamender and the Demon of the Fairy Tail, let them come they won't be able to stop us no matter what, even if they have those two monsters with them," Erigor arrogantly as he flew up a little, preparing for thr coming confrontation with the Fairy Tail guild.
