'Thoughts'

"Speech"

"Attack"

It had been one day since Natsu's screaming ended and yet the young pink-haired boy had still not awoken.

Acnologia watched over Natsu silently. There were no signs of danger yet. His breathing was normal and with his heightened senses Acnologia could tell his pulse was as well. "When will you decide to wake up brat" thought Acnologia. Acnologia lay his head down beside Natsu's body and closed his eyes. "You better be up by the time I'm awake."

Acnologia smirked at his own thoughts, or at least as close as close as a dragon can get to a smirk, before sleep claimed him. And unbeknownst to him Natsu smiled a little as well.

Inside said boys mind.

A white space with seemingly no end or beginning floated two figures. One was a young pink haired boy. Natsu Dragneel and the other was an unidentifiable was having a casual conversation with said unusual creature.

Natsu sat with his legs crossed and his arms folded his brows were furrowed as he leaned towards the creature. "So let me get this straight" Natsu said to the creature "you're a demon that lives inside me?." The creature nodded in confirmation. "And your name is end?." The creature sighed. "I already told you before it's pronounced E.N.D!" said the creature now identified as E.N.D. He looked exactly like Natsu apart from the black hair, blood red eyes, black tendril markings, wings, horns, claws, talons and the fact he was basically twice his Natsu's height.

"Yeah but end sounds waaaaay cooler" was Natsu's reply. E.N.D let out a frustrated sigh before pinching his bridge, which lead to accidentally lead to blood being drawn "goddammit" E.N.D muttered before he spoke again. "It seems like you weren't paying attention so I'll start again from the beginning."

Approximately 23 hours ago.

Natsu opened his eyes expecting to be welcomed by the forest he grew up in but alas he was denied this.

Instead all Natsu saw was a white space. Natsu then realized he was floating. Panicked by this he made a sudden movement. This of course led to him flipping and spinning around continuously.

He eventually stopped and immediately after heard a voice call out to him. From the voice Natsu could tell one thing. Whatever was calling out to him was strong. It's voice was powerful and cold it sent a shiver down his spine.

But the odd thing was it was familiar. But how? He'd never heard any voice like that ever before. And yet the familiarity would not disappear.

"The answer is simple child" the voice spoke, it was a whole lot closer now. "We belong to the same body. It's only natural for you to have heard my voice." Natsu started to spin around frantically searching for the source of the voice. "Just like how I have heard yours."

Natsu froze the voice was now directly behind him. He breathed in deep summoning up his courage. He clenched his fist tightly before twisting his body around and sending a fist towards the source. Contact could be heard but what his fist connected with surprised Natsu. It had been caught in a jet black palm. It had four claw like fingers protruding from it. Each had a grip on Natsu's fist and each were drawing blood.

"Hmm you have an impressive amount of strength for your age. It far exceeded my expectations." Natsu could tell that the creature was smirking. "I guess I should have expected that from my host." Natsu finally pried his eyes from where his fist was residing and looked towards the creature.

He was shocked to see it's appearance. It had wild spiky black hair, slitted blood red eyes. A pair of thick black horns that pointed upwards. It had jet black patterns covering his forearms and calves.

It had four claws on each of its jet black hands and feet. A pair of black bat like wings sprouted from it's upper back though if you asked Natsu he'd say they looked more like dragon wings with the way it had a leather type material in-between it's spines. And last of all it had a thin arrowhead tail that would reach down to its ankles.

"Woah" was Natsu's reaction to which the creature raised an eyebrow. Natsu quickly shook his head to after remembering something. Wait what do you mean by host? The creature released Natsu's fist. Natsu began rubbing it as the creature put on a look which made it look like it was in deep thought. "I will tell you about that in due time. For now I believe introductions are in order."

The creature locked eyes with Natsu. "My name is E.N.D and I am a-" E.N.D started before he was interrupted by Natsu "E.N.D you mean like end? Why don't you just call yourself End?" A small tickmark appeared on E.N.D's forehead "because that is how it's pronounced. Now where was I oh right. I am a de-"

E.N.D started to speak again but was once again interrupted by Natsu "Ehhhh but End is way cooler. Here say it End, End, End, End." Natsu continued to chant "End" before a fist made contact with his head. *Whack*

"shut up and let me finish you pink-haired moron!" shouted E.N.D. Natsu gritted his teeth in annoyance "Hey! It's salmon! not pink!" Retorted Natsu.

"Yeah and it's E.N.D. not End!" Was E.N.D's reply. Natsu huffed in annoyance before muttering "whatever." "Anyways" E.N.D started to talk once more "I am a demon from the book of Zeref." He stopped to check if Natsu was listening it looked like he was. He wasn't really. "More specifically I'm an etherious.

Etherious are the most powerful demons created by Zeref as such they require a vessel in which they are sealed into. You are my vessel. By the way I am the strongest etherious." E.N.D explained to Natsu. "You get all that?" Asked E.N.D. "Yeah" Natsu replied as he checked his nails. A tick mark appeared on E.N.D's forehead before he raised and brought it down onto Natsu's head. "Owwww" groaned Natsu.

"What was that for?!" E.N D facepalmed before speaking. "I've definitely got to do something about your attention span. Anyways continuing from before since you are my vessel you can obtain the knowledge that I posses and vice versa. Basically whatever I know you know and whatever you know I know.

For example the reason you could speak fluently when you were three years old was because I did" Natsu looked up as he rubbed his head "then why are you telling me this shouldn't I already know."

E.N.D sighed "Information on etherious, magic and a lot of other things can't be shared for…..unknown reasons." Natsu frowned at that. "That's stupid" E.N.D chuckled a little "yeah I suppose it is."

E.N.D stretched out his hand which caused Natsu to flinch. "What? It's just a handshake you know" E.N.D grinned and Natsu hesitantly stretched out his hand. "For a demon you're pretty human friendly."

Natsu said although his voice was a bit shaky. "Well I'm going to be stuck with you all my life. I might as well make the most of it." To that Natsu smiled. "Hey end. Have you ever killed people before? I mean aren't demons supposed to be evil or something?" Said Natsu. E.N.D didn't hesitate to answer "yes I have. If you searched my memories you would've known that. Natsu seemed saddened by that.

He'd never met any other humans before and hearing that they'd been killed before ever seeing one was a bit depressing for him. Hell the only things he's talked with are a menacing black dragon and a murderous demon that he just met. "Oh yeah" Natsu said while recalling something "If I am your host then why haven't you talked to me like this before?"

E.N.D made hummed before answering "

To put it into simple terms you weren't strong enough." Natsu 'ohhh'd' before realizing what that meant. "Wait are you calling me weak!?" E.N.D shook his head. "In a way yes. If I had shown myself sooner it would've put a strain on your body.

"That's why I could never possess your body for longer than 15 minutes before." E.N.D nodded to himself before realizing what he had said. Natsu's eyes widened at what he had said. "You possessed my body! How?! When?! How many times?!" E.N.D sighed at Natsu's many questions. "Calm down I only did it once and I don't plan on doing it again. I like it here mainly because I don't have to deal with humans."

Natsu let out a sigh of relief. "So why did you possess me in the first place?" asked Natsu. "I had nothing better to do." Was E.N.D's reply. "So you won't do it again right?" Natsu questioned E.N.D who simply nodded.

"Okay good. By the way." E.N.D hmmm'd as he glanced at Natsu.

"Would you mind explaining that again?" E.N.D would have face planted right there had there been a floor but he ended up flipping instead. "I seriously need to work on your attention span."

Present time.

"So you definitely have it now right?" Natsu nodded to E.N.D. "Good because you need to leave. I'm afraid being in your presence is going to affect my well-being if you stay any longer." Natsu frowned.

"Hey you don't need to be such a jerk about it." E.N.D didn't reply and just sent a fist on a collision course with Natsu's face. Natsu didn't have time to dodge and his eyes began to feel heavy and everything went black.

Natsu began to stir. The sounds of birds chirping and loud breathing had awoken him. He opened his eyes to be greeted by an orange sky. It's sunrise. Natsu sat up and began to rub the sleep from his eyes.

He glanced over his shoulder towards the source of the breathing. There lay the familiar black dragon. Acnologia. Natsu smiled a little. Acnologia stirred as he felt the gaze fall upon him he slowly stood up on his hind legs and spread his wings. Acnologia set his gaze upon Natsu. "Ah finally awake are we.

"Good magic training begins immediately." Natsu's face brightened at the thought of learning how to use his magic. "Your punishment for taking a day off comes first however. Three times the amount of training. Permanently." Natsu's face fell in disbelief and he had comical tears running down his face. "This is the worst."
