Whew... Sorry this took so long, but thank you all for your patience! I hope you enjoy! I'm heading off to college this week, so I've been busy staying with family and friends since I won't get to see them till Thanksgiving! Not to mention packing! Ugh, I think I'm getting motion sick just from that thought... Blergh...

"Foolish Otouto," Natsu spoke, "fighting is a lot more fun when you are fighting with a limit. Both Lucifer and Samael never want to fight, and everyone else is so weak. What fight could there be when I am the third strongest in Gehenna?"

He heard an interesting sound below, and focused his demonic hearing on the guild below.

"Oy!" He recognized the voice as Loke's, "Erza's back!"

The clamors below brought Natsu great enjoyment as he heard the shouts below. "Erza's back!" "What do we do?" "Quick, hide!" He heard everyone froze as stomps were heard approaching the guild door. He could almost imagine the stares everyone was giving the door. He walked to the other side of the guild and saw her approaching. "Oh, I thought she sounded heavier than usual." There she was, Erza Scarlet, S-class mage of Fairy Tail, carrying a big-ass horn.

He heard the entire guild just freeze, while waiting for the part he enjoyed most.

"Erza, what is that?"

"Oh, just the horn of a monster I played. Is there a problem with that?"

"No ma'am!"

"Oh? I thought that horn looked familiar…" Natsu recognized the horn from a demon, a kin of Amaimon. Not that he cared much for Amaimon. "That's impressive. Not very many humans are capable of dealing with demons, much less mid-class demons. I might be able to release some of my limits against her…"

"Now I've heard of Fairy Tail causing trouble again. This is absolutely unacceptable! Master may be lenient about it, but I'm not! Vijeeter, save your dancing for outside! Wakaba, clean up your cigarette butts! Gray, put your clothes on! Nab, stop standing there and find a job! And Macao…" She stopped there.

"Say something!" Macao panicked.

Ezra sighed, "Now, where is Natsu?"

Gray answered for her, "He got a little out of control in one of our recent fights, and he just suddenly went somewhere."

Erza stomped over to Gray, who very quickly started sweating.

Natsu decided he may as well make his own entrance, and he jumped high up in the air. When he was high enough, he changed direction downwards and readied his fist.

"Where is Natsu?" Ezra loomed over Gray.

"Karyu no Tekken! Fire Dragon's Iron Fist!" And the roof exploded. There landed Natsu, laughing his face off. "Yo, Erza! How's it going?"

Everyone was so sure that Erza was going to castrate him and then dispose of his corpse, but their jaws dropped when Erza walked up to him. "Natsu, Gray I have a favor to ask."

"Hm?"

"I need your help with something. It's a matter of the utmost urgency. Are you willing to help?"

Gray looked at Natsu, 'Me and him… on a team?'

Natsu just smiled, "Sure thing!" He mentally added, 'Plus things have been getting boring. Yesterday only showed me I need to drop some more bodies. This might be the perfect chance to curb some bloodlust.' Apparently he already forgot he massacred a prison…

"Good, we meet at the train station tomorrow."

One train-ride later after some more introductions were made, and Gray showed his magic to Lucy who got dragged along as well. On the trip, Erza explained what the mission was: to find and eliminate the dark guild Eisenwald, who were planning something with a dark magic artifact called Lullaby. Natsu was side-lined by motion sickness though. They reached the destination, but once there, Erza realized something. "Where's Natsu?"

Happy interjected, chewing on a fish, "We left him."

While Erza was busy terrorizing the conductors, back on the train, we rejoin Natsu. "Ugh, they forgot me again." He just laid there slightly limp, until he felt a presence near him.

"Oh? You're a member of Fairy Tail? Well, aren't you lucky?" Natsu felt a small sting on his face, and he realized that the speaker had kicked him in the face. "Don't get cocky just because you're one of the weak flies!" Although he quickly jumped back when Natsu burst into flames. "Whoa! Our information told us you have motion sickness though! What makes you think you could do anything on a train!"

He sweated when he saw Natsu just stand up, apparently unaffected by the train. "Well, it seems your information is a little misinformed. I just happen to be selective about when I get motion , you kicked me in the face. I'm going to pay you back just for that."

"Well, you're going to have a little trouble with that! I'm Kagayama of Eisenwald, Erigor-sama's right-hand man! There's no way I'll let you win! Take this! Knuckle Shadow!" And his shadow formed into fists that headed towards Natsu at high speeds. They impacted where Natsu was standing and created a lot of smoke.

"Ha! Take that fair -Ungh!" Kageyama went flying back into the train door, and a wooden flute feel out of his coat pocket. The temperature started rising in the cabin as the seats started to combust and the metal started to melt. Kageyama started to sweat not just from the heat, but also the intense pressure. "What the hell is this?"

"What the hell indeed." The smoke cleared, and Kageyama saw Natsu, completely unharmed. However, he was wreathed in flames like some kind of demon out of hell, and his eyes were literally glowing red. "Now you made two mistakes. One, you assumed you were stronger than me. Two, you assumed I was weak." Kageyama rushed to pick up the flute, and hurriedly put in his pocket. Natsu didn't care much about it, but he did notice it had a skull with three eyes. Regardless, "Now, what do you think the penalty for that is?"

Whatever Natsu's plans were, they were put on hold when the train suddenly lurched. Back at the train station, Erza had pulled the emergency brake switch, albeit surrounded by unconscious conductors. Natsu stumbled as he was unprepared for the sudden stop, and Kageyama took the opportunity. "Knuckle Shadow!" He reformed the shadow fists and punched Natsu through the train's side.

He crashed into the landscape, carving a very large trench while the train kept on its passage. "Ouch. Well, that's embarrassing that a human could catch me off my guard." He tried to get up but grabbed his torso in pain. "Ugh, I think I'll just lay here a while…"

Kageyama coincidentally grabbed his torso in pain as well, right where Natsu had punched him. He pulled out the flute Natsu had seen earlier. "Lullaby… Man, Erigor-sama's gonna kill me when he finds out I let a fairy see this…"

Natsu didn't know how long he laid there, but he heard a magic vehicle drive up. "Natsu!" He recognized the voice as Erza's.

He raised his hand up, "Yo, Erza!" He got up from the dirt, and brushed it off, "Heh, just thought I'd lay around waiting for you guys to show up!"

Erza walked up to Natsu, "I apologize! I got so caught up in my conversation I forget to get you! Please hit me!"

Gray and Lucy who were still sitting in the magical four wheeler just sweat-dropped at Erza' usual antics.

"It's no big deal! Although I do want to pay that one Kagemaru guy or whatever his name was for punching me out of that train. What was the guild he said he was part of? Eisenwart or something like that?

Erza grabbed Natsu, "Eisenwald?! Where did you see them? Why did you not try to stop them!"

'That must have been what they were talking about on the train… I was to busy zoning out…' Natsu replied to Erza, "Well, I tried, but I sort of got motion sick… He did have this weird flute though…a skull with three eyes."

"I've heard of that flute!" Natsu and Erza turned to Lucy, "It's death magic! Lullaby! Anyone who hears its sound will instantly be killed!"

Erza threw Natsu back onto the vehicle and took off. "Oy, Erza, slow down!" Gray shouted, "You'll overload the SE plug!"

"No choice! That train was headed to Oshibana station! If anyone hears that flute, they'll die!" Ezra forced more magic as they headed to Oshibana. "Natsu!"

"Is incapacitated…" Lucy sighed, gesturing to a car-sick Natsu as they arrived in the city as high speeds.

"Lucy-san. There was something I needed to tell you…" Happy said. "What was it?"

"I can't handle it anymore!" Natsu tried to jump out the window, but Lucy grabbed him.

"Natsu don't! You'll fall!" He struggled against her, "Ugh, you're heavy!"

"Maybe that was it? Lucy's heavy? Weird? Delicious? Fish? Hmmmm."

"What is up with this neko?" Lucy asked.

"We're coming up to Oshibana station!" Lucy say the train station, which had a huge crowd of people in front of it, while conductors tried to calm the people.

Erza stopped the vehicle in front of the station, and quickly disembarked, heading to the conductors. "What's the situation?" Then head-butted them before they could respond. She repeated the process continuously until almost all the conductors were unconscious.

Gray just face-palmed while Erza interrogated the only conductor who was smart enough to respond quickly, "Now you know why she's such a handful."

Erza walked back while the conductor passed out from fright, "Eisenwald has taken over the train station. A army unit has moved in, but they haven't returned! Let's go! Now!"

They quickly ran into the train station, but Lucy gasped when they come across the massacred bodies of the soldier regiment. Lucy tried to look for survivors, but Gray grabbed her. "No time! We need to do what we can to prevent further casualties!"

"Okay…"

They headed into the main hall, only to find an the entire guild of Eisenwald waiting for them. "Oy! How are we going to deal with them!" Lucy shrieked.

Natsu slammed his fists together, "Alright! I'm all fired up!" He added in thought, 'Finally, I get to to maul something!'

"Oy! Don't count me out either!" As Gray stripped his shirt off. Pervert…

"I wouldn't be so sure, Fairies." A gust of wind rushed through the chamber, as a white-haired man armed with a scythe descended from above.

"Erigor!" Erza shouted.

"Now, you might be willing to hunt me, but what do all train stations have, especially for emergencies?"

Erza's eyes widened, "A broadcast system!"

Erigor grinned maliciously, "Exactly!" He started floating away, "And there's a nice crowd of people gathered right outside this station. All it takes is one note, and they'll all die! This is what they get for their freedom, trampling on our rights!"

"Those rights were because you killed innocent people!" Lucy countered.

"It doesn't matter! They'll be dead soon! Gya ha ha ha!" Erigor vanished with the wind.

"Damn it! Gray, Natsu, you look for the broadcast room, and stop them!" Lucy and I will take care of these grunts!"

"Understood!" They both ran off.

"What can we hope to do against them!" Lucy yelled, until she felt a comforting hand grab her shoulder.

"I'll handle them, Lucy." Ezra shined with a radiant light, "Konso, Za Naito! Reequip, The Knight!"

Natsu ran down the hall, he and Gray having separated some time. He came to a room filled with crates, and looked around. He took a few sniffs, and proceeded to walk away, seemingly unaware of the shape materializing from one of the shadows. Kageyama smiled evilly as he took shape, and began his strongest magic spell, "Orochi Kage! Shadow Orochi!" Multiple snakes streaked towards Natsu's exposed back. "Ha! Die fairy!" Kageyama laughed, before the snakes were shredded, and a flaming fist punched him into the wall.

"Ouch… What the hell was that…" Kageyama got up from the rubble, as he felt an extraordinary heat fill the slowly looked to find a fiend personified. Natsu was wreathed in flames, so that his form was barely visible, but Kageyama could see the glowing malevolent eyes in the hellfire. "What kind of fairy is this!" He shouted in fear.

"I owe you back for that cheapshot on the bridge." Natsu said, as Kageyama watched horrifyingly as his form shifted to a more demonic one. The flames cleared to reveal the form of Iblis. "Now, let me show you true fear."

While Kageyama shrunk back in horror, back with Erza and Lucy, the members of Eisenwald were lying unconscious, while Lucy marveled at Titania no Erza's strength. "Amazing! she really is strong!" Lucy said.

"Aye-san! That's Fairy Tail's strongest wizard for you!" Happy replied.

"Now, we need to get the people away from here." As Erza walked back out, "Lucy go see if there's anyone else!"

"Okay…" they both headed their separate ways, unaware of the Eisenwald member emerging from the wall. One of the other members, Byard, gave him a message that even left him trembling. To kill Kageyama.

Outside, people were still gathering around, wondering what was going on outside, until an armored Scarlet-haired mage appeared, who made an announcement, "Attention everyone! You need to get as far away from here as possible! The dark mages here have magic that will kill you upon hearing it. Get away now!"

While everyone went into a panic, one of the conductors approached her, "Why would you cause a panic?!"

"It's better everyone get away now, than have them die here." Although she noticed the wind picking up. She turned back to the train station, and saw it was engulfed in a giant swirl of wind. "What is this?!"

"Heh, that's be my Mafu Heki: Wind Wall, fairy." Ezra turned to see Erigor coming down from the sky.

"How dare you!" Ezra readied her sword.

"Not right now, fairy, I won't let you interfere. Stoma Buringa, Storm Bringer!" A giant gust of wind pushed Erza back to the train station, where a hole opened up in the Wind Wall.

"Damn you!" She rushed back against the wall and punched it, only for it to shred her gauntlet. She didn't want to imagine what would happen if she didn't have them on…

"Ha! There is no way out of this Mafu Heki! Just stay there and be good fairies! Gya ha ha ha!" She felt Erigor's presence outside the Wind Wall vanish.

Erza nursed her arm, "Damn it…"

Back with Kageyama, things were not going so well. He had been slammed into walls, ceiling, the floor, and he was fairly certain he had more than a few broken bones. "Ugh, what the hell kind of fairy are you?!"

He gazed up at the form of Iblis, who grabbed him by the throat and bashed him against the wall, "That's because I'm no ordinary fairy." He grinned, and Kageyama swore he could see judgment. "Allow me to make proper introductions. I am Iblis, demon king of fire, and your executioner." He prepared to punch Kageyama's head clean through.

"Wait wait wait!" Kageyama held his arms in front of him, "You need my help to get out of here! Erigor-sama has set up a Wind Wall around us, and only I know how to get out!"

Iblis' fist stopped an inch from Kageyama's face. "Very well, what do you know?"

"Well, I know- hngh!" Kageyama gassed as a hand suddenly protruded from his chest.

Iblis gasped, "What?"

Kageyama collapsed as the assailant was revealed, another member of Eisenwald. He was absolutely terrified as Kageyama collapsed, only to double that terror when Iblis glared at him. "How dare you…"

"What?" Karacka gasped.

"How dare you steal my prey! He is mine to kill, and mine alone! You will pay very dearly for this!" Iblis grabbed Karacka by his throat. He struggled in vain, as Iblis lit him on fire. He screamed as his flesh melted and his hair and clothing burned away until he was reduced to nothing but a pile of ash. Iblis then turned to Kageyama. "This is a pain! However, we still need to complete this mission." He sighed, "I guess it can't be avoided."

He grabbed Kageyama by his wounds, ignoring his gasps of pain. "Demon magic! Curare!" And foul red energy streaked from Iblis into Kageyama's wounds. He shreiked in pain as the wounds painfully stitched themselves together enough to where Kageyama could function on a basic level. "If he wanted better treatment, he should have asked an angel!" Iblis muttered. After some rudimentary treatment, Kageyama woke up, but Iblis grabbed him again.

"Hey, what are you doing! You need me!"

"Yeah, but I can't very well let Fairy Tail know my true identity now, can I? Nobody I've ever shown my true identity has lived, but I can't kill you right now. Fairy Tail can give me at least a decent challenge, so I intend to stay for me, however, you put that at risk since you know. Fortunately though," Iblis' eyes glowed red, "there are ways around that. Submitte!" Foul magic worked its way into Kageyama from Iblis' eyes, completely destroying his free will.

Kageyama collapsed limply, his head down. When he finally lifted his head again, his eyes had a red outline to them, "Now lead me back to the Wind Wall."

"Yes, Iblis-sama…" Kageyama soullessly responded.

Iblis heard footsteps coming as Erza, Lucy and Gray barged into the room. Erza looked around and she saw two people, Kageyama standing with... Natsu. "Natsu! We have a problem! Erigor's set up a barrier around us!" Erza responded.

"It's alright!" Natsu gestured to Kageyama. "This guy's willing to help!" Though he telepathically communicated, "Around them you will call me only Natsu. Follow exactly what I say, and answer truthfully."

Natsu ran out, "Let's go!"

They headed out to the Wind Wall, where Erza approached Kageyama, "So is there way out of here?"

Kageyama replied, "No. The barrier is absolute."

Natsu grabbed him, "What?! But you said there was a way out!"

"I lied."

"Why you-" Natsu readied his fist.

"Natsu!" Erza grabbed his arm, "Now is not the time! We need to figure out where Erigor is going and how to get out of here!"

"Erigor-sama is going to the guild masters' meeting to exterminate them all."

"WHAT?!" Was the unanimous response.

"Oy oy oy! We need to get out of here now!" Gray shouted.

"Well how do you propose to do that, stripper!"

"AHHHHHH!" Happy suddenly exclaimed.

"What?!" They all shouted.

"Lucy, I suddenly remembered what I needed to tell you! And he pulled a golden key out of his knapsack.

"This is Duke Everlue's key for Virgo! Did you steal this neko!" Lucy started stretching poor Happy's face.

"Virgo approached me after Everlue was arrested, and said she wanted to be your spirit."

"Well, why didn't you say so, baka neko! We can use her to dig us out of here!" She pointed the key away from her, "Open! Gate of the Maiden! Virgo!" And a maid popped out, with pink hair and chains on her wrists.

"Punishment time, Hime-sama?"

"Wha-?" as Lucy thought back to the giant gorilla she was before. "What happened to you?!"

"I take the form of what my master desires me to be. I can go back to my old form if that is what you prefer." She shifted to a giant hulking gorilla behemoth of a maid.

"No thank you!" Virgo turned back to her new form. "Anyway, I'm sorry to do this without a contract, but are you willing to dig us out of here?"

"Very well, hime-sama." And dug a hole.

Erza gave a command. "Let's go! We need to stop Erigor! NOW!"

However, Natsu glared at Kageyama. He does not appreciate being used or lied to. He is the one that does the using, and he is the one that does the lying! He gave his last mental command. "Kageyama. Walk into the Wind Wall."

Kageyama started forward, as Lucy and Gray were starting through. But Gray noticed, "Oy, what the hell is he doing?! Erza, stop him!"

Erza turned but she was too late. Kageyama jumped head first into the Wind Wall, and blood splattered everywhere as his head was shredded by the intense wind. Natsu just smiled, satisfied he had gotten his revenge.

Lucy gasped, "Why did he do that?!"

Natsu stared at the headless corpse of Kageyama. "Who knows? No time to mourn now! We need to get going!"

After they had all crawled through, Erza gave her next command. "Natsu, you and Happy are the fastest among us. You follow Erigor. We will follow you on the four-wheeler! GO!"

Natsu nodded, "Understood!" And he and Happy took off in hot pusuit.

Further away, Erigor was flying as fast as he could towards the meeting hall of the guild masters, "Soon, we can avenge the injustice done to us at the hands of the legal guilds!" Before he felt a magic spike, and a burst of flame flew past him, which he barely dodged.

He turned back to see the Salamander flying behind him at high speeds. "You won't get away with this Erigor!"

"You won't interfere, not when I'm so close! Take this! Storm Burst!" And he fired extremely fast-flying spheres of air towards Natsu and Happy. Natsu dodged most of them, but one struck Happy and sent flying far away, while simultaneously dropping Natsu.

"Natsu!" And he vanished into a light in the sky.

"Happy!" Natsu shouted as he fell into the cliffs below.

"Ha! Take that fairy! Not so useful without your wings, are you! Gya ha ha ha!" Only as a very swift moving form punched him in the face. "What the hell?"

The form kept moving and moving, delivering vicious punch after punch, until Erigor had had enough. "Bastard! Storm Bringer!" He unleashed a tornado that caught that shadow in its path.

"Ha! I don't know what you are, but nothing has ever escaped from that spell!"

"Until today." And the tornado exploded in a burst of flame.

Erigor shielded his eyes, until the smoke cleared, and stared in shock, "What?!"

There was Natsu Drageel, the Salamander, but not the one he had seen before! This Natsu was flying without his cat, with a pair of leathery wings. Demon wings! His eyes also glowed red, and he seemed to have some small horns on his head. He froze as Natsu fixed his crimson eyes on him, while smiling.

"Oy, Erigor. I'm going to kill you."

I hope you all enjoyed! I hope you also enjoyed it enough to leave a review! It honestly started out rough, but as I typed more and more, I think it got better. But it took me a while. I pretty much got through 4 Naruto movies, and the ANE movie before I finished it... (I can multi-task! I swear!).

Again, please review, or else I will have the Jiggle Butt gang gas you... Cheers!
