Hello everyone, sorry I haven't been uploading lately. A lot of things have been happening lately. I've been feeling a little depressed about my progress in school. I'm not sure if it's anything too serious, but my motivation for the things I like to do has been going down. I'm starting to get back into the swing of things though. I still want to take my time with this story so I can do it some justice. I really like both of these anime, so I really want to get this right. Sorry if updates aren't as fast as they could be, but I'm doing the best of my current ability. Without further ado here's Chapter 4 of Demon Fairy. Also Fairy Tail is owned by Hiro Mashima and Blue Exorcist is owned by Kazue Kato.

{Earthland – Kingdom of Fiore, City of Onibas – Train Station}

"HOW COULD I HAVE DONE THAT!" Erza yelled as she paced around in frustration. The red haired woman had been stating her disbelief for a few minutes now. "I was too focused on talking that I failed to notice that Natsu wasn't with us! Will one of you please hit me?" The re-equip mage asked while dramatically turning for no reason.

"It's okay Erza no one blames you, right Rin?" Lucy asked trying to calm down Erza

"Yeah, besides Kuro's with him, so he's going to be fine" Rin said

{Earthland – A Train head towards Kunugi Station}

Kuro had just woken up from his nap. Rin was moving around too much he moved towards Natsu's lap since he wasn't moving. Everything was clam and peaceful until someone came and sat down in front of the flame wizard.

{Back at the Train Station}

"Sir please it's for our friend" Erza said to a conductor

"Miss for the last time, we can't just stop a train because your friend was too stupid to get off!" The conductor said as he tried to explain for like the fifth time

"Okay, I understand complete- HAPPY NOW!" the red haired mage yelled out as the blue cat flew towards the control panel and pulled the emergency break.

"Was that necessary?" Lucy asked

"Now that the train's stopped we must go after Natsu" Erza said ignoring Lucy's question

{Back on the Train}

"You know now that I think of it, that hottie Mirajane is in your guild right?" The man said as he continued to talk to Natsu about guilds. Kuro was barely able to keep up with what was being said but because so far this guy was just talking about girls that were in the guild. Honestly it was a little creepy especially since he could tell that Natsu was still unconscious. This guy was giving Shima a run for his money.

"I can't help but notice that there a lot of cute girls in your guild, unfortunately there are no girls in my guild. Think you could spare some?" The guy asked bringing up girls again. Kuro was about to grow and pounce on the guy when he suddenly kicked Natsu in his face.

"Don't go ignoring me just because I'm from a dark guild you punk!" The mystery man said as he kept kicking Natsu. At this point the fire mage had woken up and was fully aware of what was going on.

"Man your guild must be pathetic if they don't even fight back!" The man said angering Natsu

In response Natsu began to activate his dragonslayer magic, but since he was still on the train it began to fizzle out as soon as it started.

"Haha! What kind of magic is that!" The man said as he got up "You have to use your magic like this!"

The man's shadow then morphed from the ground and formed a fist and punched Natsu onto the floor. This caused the man to laugh hysterically. Kuro couldn't stand this man any longer, so he finally grew to his full size and pounced on the creep. As Kuro pounced the train came to a complete stop. As it did the man's bag fell to the ground and a weird skull flute fell out.

"Oh no you saw it!" The man said as he tried to grab his flute.

Before he could pick it up Natsu got back and was at full flame. He rushed over to the man and punched him at full power through a few train cars. Natsu wanted to finish the fight and Kuro seemed to want to help him out, but an announcement from the train conductor stopped him cold in his tracks.

"Sorry for the inconvenience passengers. We have just confirmed that the emergency brake was a fake. We will resume movement temporarily"

Hearing this Natsu grabbed his bags and began to jump from the train.

"Stop! You just picked a fight with the Eisenwald guild! Don't think you can just run away that easily!" The man said as he struggled to get up from the wreckage that Natsu had caused.

"The same goes for you too! Don't think you can just badmouth my guild and get away with it!" Natsu yelled as the train began to pick up speed. "Oh no! Let's get out of here Kuro!"

The cait sith then lowered its body for Natsu to jump on. Once he was secured Kuro jumped out of the train with Natsu on is back.

As this was happening a magic four-wheeler was coming up next to the train at dangerously high speeds. On it you could see Erza driving while Lucy and Gray were inside, and for some reason Rin was on top of it holding on for dear life.

Rin then looked ahead and noticed that Kuro had managed to get Natsu out of the train, but now they were directly in the path of the magic car that was about to run them over.

"Erza stop!" Rin yelled out as the scarlet haired mage stopped feeding power into the four-wheeler. This caused Rin to be flung forward as he collided into Natsu, causing the two to fall to the ground.

"Sorry Natsu" Happy said as he and the other Fairy Tail mages ran over to the two

"I'm fine too you know." Rin said as he got up.

"Sorry Rin, we were in a hurry." Kuro said as he shrunk back down

"Wow, I didn't know that Kuro could grow like that!" Happy said as he wondered what he would look like if he could grow.

"I'm so happy you're safe" Erza said smiling as she grabbed Natsu by the back of the head and forcefully slammed his head into her breastplate.

"Wow, it's times like these that I'm really glad that my friends don't worry about me the way these guys worry" Rin thought as he looked on at another bizarre display of comradery that the Fairy Tail guilds tends to give

"I'd be better if that Eisenwald jerk didn't get away!" Natsu said just barely recovering from the blunt force trauma that his fellow guild mate had just inflicted upon him.

Hearing this the red haired mage pulled a hand back and slapped the dragonslayer with all her might, sending him back 10 feet.

"YOU IDIOT WE'RE AFTER THE EISENWALD GUILD!" She yelled "WHY WEREN'T YOU PAYING ATTENTION?!"

"It might have something to do with knocking him out?" Rin suggested

"It doesn't matter now." Erza said ignoring Rin's previous statement "If we follow the train we can catch up to him. Did he have any distinguishing features?"

"Not really, expect he had some weird wooden flute with a skull that has three eyes in the end." The fire mage explained thinking back to his encounter on the train.

It took a minute for everyone to take in what Natsu had just said. He didn't really give a good description of who they were after, but he did manage to confirm their mission objective.

"That was the lullaby flute!" Lucy exclaimed "A wooden flute with a skull that has three eyes, that's the death magic flute Lullaby!"

This caused everyone around her to tense up for a moment

"Anyone who hears music played by that flute is marked with death magic, I've only ever read about it in books but I never thought it would be real." The blonde finished

"We have to hurry now!" Erza commanded as they all got into the magic four wheeler while Rin and Kuro ran beside them.

{Earthland – Kunugi Station}

The train that Natsu and Kuro were previously on had been stopped by the entire Eisenwald guild. Currently all of the guests and even the conductors were being forced off of the train.

"That's right, everyone off. This train is now the property of the Eisenwald guild!" Erigor declared as his underlings cleared the train.

After making sure that none of the guests or any of the conductors were still on the train Erigor shifted his attention to Kageyama.

"We heard that you were taking this train so we've been waiting here for a while." Erigor said grinning like a madman.

"You have great timing, I managed to break the seal." Kageyama said as he handed Erigor the flute

"So this is Lullaby huh?" Erigor pondered as he examined the flute "It's said that this was just a regular 'death curse' flute, but the Dark Mage Zeref went further in developing it. Now it's a 'mass murder' death curse. Anyone who hears a melody played on this flute is instantly marked for death."

The rest of the Eisenwald guild began to cheer as they heard this.

"Yeah not even those Fairy Tail flies can stop us now." Kageyama said as the cheering began to simmer down.

Hearing this Erigor's grin began to disappear and was replaced by a look of dissatisfaction.

"what do you mean by, 'Fairy Tail flies' Kageyama?" Erigor asked trying his best not to kill the person who just handed him one of the most powerful death curses in all of Earthland.

"Some Fairy Tail wizard was on the train about a minute ago, but I dealt with him"

After hearing this Erigor sent two gusts of wind towards Kageyama. They traveled so fast that they sliced both of Kageyama's ears. Kageyama wailed in pain as he clutched both of his now separated ears and fell to the floor.

"Tell me Kageyama did he see the flute?" Erigor asked not sounding happy that one of his men screwed up.

"So what if he did?! No one can stop our plan at this stage, not even Fairy Tail!" Kageyama yelled as he continued to hold his ears.

"I know what much, but I still don't want anyone getting in our way." Erigor said "Alright listen up everyone here's what we're going to do."

{Fairy Tail Mages – Currently in Motion}

The magic four-wheeler that the Fairy Tail mages were using was barreling down roads so fast that they were knocking over tables and breaking street signs. Behind them Kuro was struggling to keep up with them, but he was still able to stay on their tail.

"Erza slow down! You're going to overload the S.E. Plug and I don't think Kuro can keep up with us at this speed!" Gray said holding onto the roof of the four wheeler for dear life.

"If that flute get played, too many lives will be lost!" Erza said as she focused more on the road

"I get that, but if you use all of your energy before we reach them you won't even be able to use your magic" Gray said trying to convince his friends to slow down.

"I don't care about that, besides if it gets that bad I can always just use my bare hands" Erza "Not to mention that I have you guys helping me too"

Gray couldn't say anything else after that so he just remained silent for the rest of the ride.

Not too shortly after their conversation they noticed smoke coming from ahead.

{Earthland - Oshibana Station}

There was a large crowd outside of the train station as multiple conductor tried their best to keep every from entering the building. Their pleas of "Remain calm" fell on deaf ears as news of Eisenwald's occupation of the station reached the public.

Meanwhile Erza had disengaged the magic four-wheeler and began to cut through the crowd with everyone in tow. Lucy was currently carrying Natsu while Rin let Kuro rest on his shoulder.

"Erza, I don't think we can just go in there." Gray said trying once again to be the voice of reason.

"We don't have time for that!" Erza said as she made her way to the front of the crowd.

"Tell me what's going on inside!" Erza demanded from one of the conductors. The man was just confused as to what she meant and before he could answer her, Erza headbutted him so hard that he fell unconscious.

"What's going on inside!" She asked another conductor only to be met with the same result. This continued for some time until all of the conductors were laid out on the ground.

"Oh man, she's scary." Rin said with a fearful expression on his face

"She really doesn't like people who take too long to answer her huh?" Lucy asked with the same expression on her face

"Yup, now you know her a little better" Gray said with same expression

Hoping to avoid ending up like the conductors the three of the plus Natsu who was still sick went into the train station to see a bunch of soldiers on the ground.

"What happened to these guys?" Rin asked

"They're military soldiers, but since they were going up against a guild they didn't stand a chance" Erza said as they all made it to the main concourse area to see the entirety of the Eisenwald guild in front of them.

"I knew you'd be here Fairy Tail. Welcome to your doom" Erigor said holding his scythe behind him

"So you must be Erigor." Erza said as she stared down the leader of Eisenwald

"Natsu now would be a good time to wake up!" Lucy said trying to shake him awake

"It's impossible, he went from a Train, to a giant cat, to magic four wheeler, then to you it's a massive combo!" Happy said exaggerating

"Wait why is Kuro included in there? Why am I included in there?!" Lucy asked as Rin set Kuro down next to Happy.

"Hey can you watch him for me?" Rin asked as Happy nodded

"Tell me what you plan on doing, if I don't like your answer then you're going to have to pay for it." Erza said as magic began to flow around her.

"We're not doing anything besides killing time." Erigor said as a few goons began to chuckle. While they were doing this Erigor floated up to the second floor with a mighty gust of wind. "Think about it, what's inside of a train station that would benefit us right now?" Erigor asked with a sick grin.

The Fairy Tail mages stopped for a moment to think about what Erigor had said. They had a head start on them and could have gotten away by any other mean, but they decided to take a linear track and highjack a train station. What could be here that can't be found anywhere else in a short amount of time. Erza then looked up near where Erigor was and saw a loud speaker and put two and two together.

"YOU'RE GOING TO BROADCAST LULLABY?!" Erza yelled in shock as she had deduced their plan

As if to confirm her fears Erigor began to laugh like a mad man. "There are hundreds if not, thousands of people outside. If we broadcast Lullaby's sound through the PA system, we'll kill them all! This is for taking away our right to being an approved guild, and those who live to benefit from guilds must be killed!"

"But if you kill those people you won't get those rights back, if anything you'll just prove that you don't deserve them in the first place!" Lucy shouted out

"You don't get it, we aren't out to right any wrongs. We're going to clear the map so we can control the narrative" Erigor said holding their attention "You're such a fool!"

"Take this you damn flies!" Kageyama said a shadowy hand made its way past Erza and Gray straight towards Lucy.

Hearing Kageyama's voice Natsu woke up and made a flame so bright that it caused the shadow to dissipate.

"So we meet again, this time we're an even playing field." Natsu said as he created a fireball in his hand. The Fairy Tail mages and the visiting Exorcist were face to face with each other as a clash was about to begin.

Okay so I originally intended for more action to take place in this chapter, but it already got too long. By the time I got everyone at the train station this thing was already at seven pages. So next time we finally get to see Rin fight along side the Fairy Tail mages. Sorry if this follows the canon a little too closely but trust me when I say that Rin is going to shine more in the next few chapters. Until next time I've been Dragolianx-Unlimited and I'll see you in the next chapter

P.S. Thank all so much for following and favoriting this you don't know how happy that makes me.
