- Prologue: The Truth Behind it All -

It was a hard fought battle for them.

They never thought that this battle would give the scars weighing down to their hearts as sacrifices are made between friends and families in order to break through the hopelessness of the situation. There are times where they have come to decisions that soon changed them into many different ways and move on to the future.

The battle between fairies and demons has finally ended although it was unprecedented that Acnologia made his appearance once more and caused more destruction and despair among the people.

Everyone would've died in his hands if not for the dragons who also appeared out of nowhere and helped the humans against their fight with Tartaros and the Black Dragon of the Apocalypse altogether.

For sure they drove him back but with a heavy price as Natsu stared tearfully at the torn body of his foster dragon who now lay defeated and was on the verge of death after taking a brutal hit from the black dragon. He was just right there, standing helplessly as his father was mercilessly killed in front of him, unable to do anything to save him even after all the years he's been training to become stronger.

For years, he's been searching to reunite with his foster dragon yet-

.

.

-it was for a moment until he was gone once again, this time finally forever.

He didn't want it. He wanted to share all the things he had experienced in his life during his sudden disappearance. The things that he wanted to tell to him for not seeing him for all these years. Not to mention, the number of people and friends that he met along the way.

There's just... too many things for him to tell him about his life but-

.

.

It was all over.

He never got the chance to say anything nor to say something to remind him of all the memories he shared even without his presence.

"Igneel... Don't leave me." His words followed by a wave of tears from his eyes as the body of the defeated dragon king begins to glow in bright light, seemingly disappearing in his eyes once more.

Despite his cries, there was no response. Nor any words to part him with as a large array of light shone over the distance. Natsu probably thought the same thing that would happen to the other dragons as well since he caught a glimpse of them flying around it before disappearing for eternity.

He's pretty sure that the others also felt the same but not to the extent of this sadness and despair as him.

"Why?! Why am I so goddamn weak?!" He cursed himself for not being able to become stronger that his father wanted him to be.

Dragonslayer? Is that title even worthy to him? He can't even take down a single dragon on his own dammit! There is a huge gap between him and the dragons that he fought back at the Eclipse Gate. He hated himself for not being able to fulfill the role of the dragonslayer that Igneel entrusted him so much about.

Is it really unavoidable? For him and the others to be not powerful enough to stand up on their own against these enemies? Are they just fated to lose their parents at the very first place?!

Those questions simply buried right inside his mind, remaining unanswered as the flickering lights from his father's body finally disappeared right in front of him forever, leaving him alone once more in this ravaged battlefield.

And finally for the first time ever, he felt cold.

"So Igneel even never stood up a chance, huh?" It was then a voice resounded from out of nowhere as Natsu was able to recognize its voice and alarmingly turned towards his side as he saw the infamous Black Mage standing over at a distance, staring at the place where Igneel last disappeared into.

Despite his usual expressionless nature, it was odd to see him showing signs of sympathy over to the fallen dragon as if he was related to it.

"Zeref!" Uttering the name of Black Mage himself, Natsu gritted in anger as he found the perpetrator who's behind all of this.

Without thinking, he lashed out to him in pure rage as flames spew out from his fists and launched his attack on him. However, Zeref never showed any signs of backing away as he met his flaming fists directly, staggering himself in the process but sustaining no damage at all as if it didn't even hurt a single bit.

He never even regarded the dragonslayer's hostility and capability to be a threat to him. After all, he could kill him anytime he wants to with his magic alone but-

.

.

he never wanted to all that since he was his...

"You killed him! I'll never forgive you!" Natsu shouted in rage as he continuously poured out his power towards him without stopping as his attacks hit their marks and was pushing him back in the process but Zeref never showed any signs of pain in him and was freely taking his attacks head-on.

"This was still the same ever since back at Tenrou Island... Natsu." He spoke in a monotone but Natsu ignored him and continued on his onslaught against him.

"This time will be different!" He declared as his body suddenly begins to form up scales and his face having scaly-like features, signifying his use of the Dragon Force at his own free will for the second time.

True enough, the power delivered towards him got even more powerful as Natsu sent the black mage away from the vicinity and crashed into a distance but not before long Natsu caught up with him and continued deliver more powerful attacks on him without stopping.

.

.

However, despite his new power and final form as a dragonslayer, Zeref never once took any real damage. His face was full of scratches but there's not a single pain to feel with as the pinkette's attacks were nothing to him. With an instant regeneration, he returned back to his normal self as Natsu felt shocked to see that his attacks had no effect on him whatsoever.

Even with the use of his Dragon Force, there was no real damage at all.

Just how powerful is this person?

Eventually, he was beginning to lose power and the form cannot stay for a bit longer as Natsu had his scales disappear on him once more, giving him a huge wave of exhaustion as he went down on his knees, heavily panting from the overuse of his powers just now.

Even with that, Zeref only looked at him with the same expression as before.

"It seems that you're not even strong enough to kill me, Natsu... ... Should you become stronger at this era, the world might stand a chance once again and probably end the cycle of destruction but-

-you're not that powerful enough to even match against him. Igneel had his own way to making you stronger but it seems like he failed."

Hearing the name of his foster dragon, Natsu looked at him with confusion despite his weary condition.

"W-What do you know about my father?!" Instead of answering him, he simply gazed off into distance, recalling the past events that he had with the late Fire Dragon King in which Natsu had no knowledge of.

There was a moment of silence between them until he began his side of the story.

"E.N.D." He spoke in which caught Natsu's attention as he began to mention the same book that Igneel wanted him to retrieve back from Mard Geer but right now, the book is in the Black Mage's possession. Who knows what would happen if ever tried to use the book right now?

There would be a massacre since he and his friends are still coping at the loss and energy from their fight against the last head of the Balam Alliance.

"What are you talking about?" He replied with irritation as eyes narrowed in suspicion.

"The book that Igneel wanted to take from the demons of Tartaros... He longed to get it in his hands since that book resides the most powerful Etherious that I've ever created."

"Of course he would! That book is dangerous for anyone to be held by someone like you."

"You're wrong... It is not by the reason that it's dangerous to him but rather-

-it's something that he wanted to keep it in order protect you." He revealed which only surprises him even more as he somehow knew his relation with Igneel as his foster son.

"H-How did you know about that?!" He demanded an answer but Zeref could only shook his head with his eyes closed in wonder.

"It's a memory of the past... However, with things right now, I guess there's no need to hide it any further..." He paused before looking back at the exhausted dragonslayer in front of him.

"I'm Zeref Dragneel... I'm your brother, Natsu Dragneel." He placed a blank smile as if it heeded no emotions that fits his character.

It was then Natsu was shocked to hear such a ridiculous claim.

Zeref? His brother? That's total bull! How in the world would he be related to a man from the past to the him?

Sure, he knew his relationship between him and Igneel but that doesn't mean that he claims to be his legitimate brother. He had no family other than Igneel himself. There must be some sort of mistake here!

"Stop all saying such crap! That's impossible!" He shouted in defiance.

"Perhaps I could prove it to you in some other way..." He paused as he summoned the book of E.N.D on his hand which caught his attention.

"... This has been the attention of some other cults as well since I created this to be the most powerful Etherious that may even rival that of Acnologia as well. It's no coincidence of why Acnologia wanted to destroy E.N.D. because it's a threat to his domination. I'm not here to explain the history of it. Rather, I'm here to show you what this book really is and why it was important to Igneel as well."

He dropped the book down to the ground as Natsu carefully watched it fall as Zeref continued once more.

"E.N.D- No, or should I say Etherious Natsu Dragneel." He slightly smirked as Natsu widened his eyes in shock at the real meaning of the book itself.

"W-What!"

"That is you, Natsu... You're the strongest demon I've ever created. My own brother infused with the power of the strongest Etherious."

"Cut the crap already! I ain't listening to the same shit you're trying to say-" A striking pain went up from his bottom chest as Zeref launched a dark beam towards the book itself in which case, it reacted to the same as Natsu's body who could only scream in pain as his body was instantly shot up with huge loads of pain afterwards.

"See? You were never one to listen... ... I'm here for you to acknowledge your existence."

"I-I-I won't!" He denied.

"Then I'll remind you something again, Natsu... ... In time, only two will be able to meet me again in the future. Whether it would be you or E.N.D. himself will be able to make it to the very end." He turned around to leave as he left the book before it started glowing it dark red as flames surrounded it before vanishing completely and turned into a sea of red fire before flying towards Natsu who could only shield his eyes in response.

The flames sipped into his body as a large surge of power was felt by him in which his body also goes for a dramatic change. His hair was starting to turn crimson and his eyes glowing in bright red color, signifying that of a beast.

The once bright color of his flames, forever replaced with dark crimson color. His canines become more sharp than ever and two protruding small horns slowly began to appear above his head until a large pain surged again all over his body, causing him to lose his strength and succumbed into its torture as the transformation continued.

"W-What's happening?!"

"I simply returned right where the book is... ... Mard Geer was oblivious of this. There is no such thing as the revival of E.N.D... After all, he is just sleeping, waiting to be awakened once again. You and him are one... Both loved by Igneel so much that he didn't want to finish you after all. And instead, he tried to teach you the ways of life..." A light smile went on towards his lips as he turned around away before vanishing but not before he parted with his last words over to the pinkette once more.

"The final battle is approaching... ... I want you to surpass me, Natsu... I hope that you would gain your power enough to eradicate both me and Acnologia altogether..."

And with that, his body faded into distance, leaving the distraught pinkette alone with many shocking truths and revelations that he still wanted to process inside his mind. The truth behind his past and his nature has finally come into light.

There was no other way to deny it.

He was E.N.D.

The person behind this pain and suffering. The one who inflicted a lot of scars towards his friends and brought them sadness.

Guilt instantly went through his heart as tears immediately poured out from his eyes, ignoring his transformation but rather realizing the fact that he caused all this mess and hurt his friends without even knowing it.

He started it all.

"W-What have I done?"

A/N: And stop! That goes for the prologue. Hope ya like it.

Alright, this is the part where the journey begins with Natsu as END from now on. Of course, I would try to retain some of his personality but some would be changed since the truth was finally revealed to him. The awakening is just beginning of course, the story might focus on his inner turmoil between his END nature. Should he deny the powers or just accept it as part of his own kind of thing.

Anyways, the story is just as the same with the others so it will receive some updates but not regularly unless I got the drive. Even so, I'd like to hear out your thoughts on this new story in order for me to think up all the new things that might come in the future chapters also.

Thanks again for reading, I'll see you in the next chapter.
