- Prologue: Forgotten Dream -

..

..

The time has finally come.

Centuries of embracing cold, the once great fires will be lit once again.

Beings bearing the incarnate of destruction will return,

and claim its rightful place in the sky.

In the age of strife between mortals and gods, a red earth will be imminent.

The endless cycle of discord will be shaken down to its very core.

The long fated day will come upon the rise of a being mingled in both human and dragon.

The long awaited time is over.

It's time to awaken..

Son of Igneel

..

..

Kuoh Academy... (Morning..)

Natsu slowly opened his eyes awake for some reason as he tried readjusting his surroundings once more to the bright and vibrant classroom of where he's currently at. The cause of this uncomfortable awakening was due to his enigmatic dream earlier. Images of destruction and flames rising from the earth and brought forth an image of a red sky with the aid of a red moon right from the above. It's already been two weeks ever since experiencing the same dream over and over again. He might need to get a psychologist to examine his mind since it doesn't often happen to most people.

Yawning silently from his seat at the corner of the room, the pinkette outstretched his arms in front of him to give him a bit of a stretch from his growing sleepiness. Despite having to sleep at an early time last night, he still haven't gotten enough to shove the feeling out from his system.

However, as he was about recomposing himself, a mildly loud tap was soon heard from in front of the table as both eyes of the other classmates darted over to him while he simply looked towards the front with the teacher slamming her book right on her desk which was the cause of the unwanted noise.

"Natsu Dragneel, I see that you're probably awake now... Care to explain your reasons of falling asleep?" There was a hint of displeased tone on her voice as the class went quiet all of a sudden and focus on him solely, mush to his irritation of being the center of attention.

"No, none at all... Just bored." He bluntly replied while making at least some of the other classmates to chuckle at his response but it only fueled the teaher's discontentment towards him.

"Oh, I see... While I'm surprised that you're being honest this time, I still have you to report for detention after class so be warned, mister." After informing of the punishment, the teacher returned to teaching, subsiding the intense stare of the other students, causing the pinkette to breathe a sign of relief before gazing towards the window right beside him in thought.

It was a normal day occurrence for him to be sent to detention like this. It's a miracle that he managed to get all through the middle-school without ever being repeated at the same time. His grades were average but his relationship towards teachers and other students are below at that. It's not like he had any ill will against them, it's just that he doesn't find himself to be among them.

A confusing mindset really.

Despite that, he still has some connections with other students who were more open to him rather being judgmental just because of his bizarre hair color. That's right, everyone seemed to think him as a problem child because of his pink hair. It's not like you'd see a person having pink hair that often and being a male is a such a rare sight to see. There are even others who would think that it was purposely dyed to increase his popularity. Like he cared all of it though.

Taking a second sigh underneath his breath, Natsu lowered his head to rest upon his arms while looking wearily at the teacher, teaching stuffs and other baseless craps for the betterment of his future.

'Screw studies!' is what he said inside his mind. Why would something as boring as this be part of the institution? Although, he might need to not proceed that question any further if doesn't want to become paranoid.

And with that, he simply closed his eyes once more to sleep. He would hope that the same dream wouldn't have to haunt him this time.

..

..

..

A loud sound of a ringing bell soon sprung him back to life as his eyes twitched open before readjusting them towards his surroundings before catching a glimpse of some of his students, leaving the room while others staying to converse with their friends. It's probably lunch time so he might also need to move out as well to save time.

"Another detention again huh, Natsu..." A male voice resounded from his side as Natsu tilted his head slowly to the right and met up with the person before instantly recognizing him.

"Looks like it." He spoke nonchalantly before taking a wide loud yawn from his seat to completely knock his sleepiness away before returning his attention towards the person.

"You know, mom and dad are not gonna like it if that keeps going though it has nothing to do with me but still-" He was cut in mid-sentence as Natsu began to speak for himself.

"Don't worry, it's the just the start of the second spring semester and this is just the first so I can handle it."

"Come on, Natsu... It's not like it's going to keep them from getting worried."

"Well, I would be more worried about your perverted nature, Issei." The boy named, Issei snorted irritably as he suddenly retorted in defense of his personality.

"To become perverted is a way of becoming real men, Natsu... It's more fun than you being... uhh... uninterested to girls and oppais!" His declaration soon caught attention of the other girls who could only look at him in scorn and disgust.

"See? Even the girls don't agree to that... Myself included.." Natsu joked.

"I somehow don't get why you wouldn't have anything to interest you in any way involving oppai except for fighting..." Issei pondered.

"Who knows... Fighting is also part in human nature..." Natsu replied.

A sigh from Issei soon followed as he simply looked at his pseudo-brother with worry. It's already been a long time since Natsu became part of the Hyoudou family. Apparently during the time of Issei childhood, his parents eventually caught sight of a severely injured yet alive kid just outside their residence. The injuries were mostly from burns and scars that made all of them to worry as they sent him immediately to the nearest hospital for treatment.

No one sure knows of what caused him to inflict such a deadly wound. They couldn't even figure out his parents since he was left alone except for a engraving sign that was seen on the pavement beside him from where he was seen, spelling out "Natsu Dragneel"

It was the only thing that gave information of the kid. Even after being recovered from the burns, it came to a surprise as well as the boy named, Natsu wasn't able to remember anything that could've linked to his past. As a result, the Hyoudou couple could not help but adopt the poor kid out of sympathy about his painful experience. Being abandoned without anyone or anything to remind him except of his name, Natsu pretty did have a rather bad childhood at that time, seeing that he did not harbor any emotion at the start of his recovery.

It only came at a time when Issei was finally able to establish a strong bond between them despite him being an adopted brother of the family though he didn't expect him to turn out to be a energetic person who loves fighting without the same feeling towards the opposite sex. Even so, the two brothers maintain a stable relationship between each other and had been the best of friends ever since.

While briefly reminiscing their pasts, Issei could only smile in relief towards the pinkette before another pair of boys came into view, particularly looking for the brown-haired boy specifically.

"Yo! Issei! I see you have been talking again to your brother huh? Quite a straightforward answer right there, Natsu-kun!" The boy with glasses smiled with a thumbs-up towards him, making it seemed like a compliment or an insult for that matter.

"You're welcome, Motohama." Natsu warmly welcomed the statement.

"Well, since you have bad reputation like us, why not join us and strive for our goal to create a harem in this recently co-ed school?!" The other boy suggested in which Natsu passed a disapproving wave on his hand before resting himself on the desk once more.

"No thanks... I'd rather not have myself be beaten up by most of the girls here in this school than risking for some stupid oppai.."

"IT'S NOT STUPID!" Both three shouted in irritation towards him, deafening his hears in close proximity as he instantly stood up and back away from the three.

"What the hell? You three could've broken my ear, dammit!"

"You started it... You said oppais are stupid..."

"I bet you never even experienced one."

..

..

"I never did once and would never be in the million years." Natsu stated which only shocked the three who on the other hand, turned stone-faced due to the shocking answer to them.

"He really did say it... He's not a man."

"Oi! Shut up..." Natsu retorted and not before long he sighed once again before turning his attention towards the door and started walking out, leaving the other three behind. "I'll be getting some food in the cafeteria... I'll come back later."

But just as he was about to leave, his eyes soon caught sight of a red hair flowing right past him, prompting him to glance back and eventually saw a young woman walking right past the hallway with red hair as the other females stopped for a moment and watched her walked right towards the corner and turn once more. But just as she was about to disappear from the corner, Natsu was able to notice a slight glimpse of her gaze towards him that soon made him uncomfortable all of a sudden.

A moment of trance soon followed until the three boys from earlier also arrived by the door though missing the wonderful spectacle of the woman walking right past the hallway.

"Ah damn, we missed her." Matsuda gritted.

"Who was that girl?" Both Natsu and Issei asked in confusion, not entirely aware that such a person would be here in the campus.

"Rias Gremory... 99-58-90. A senior and the president of the Occult Research Club... She's rumored to come from Scandinavia." Motohama explained.

"I didn't ask for the sizes though." Natsu deadpanned.

"I'm surprised that you two never even knew her. Well normally, she stays around the old building just at the other side of the campus and she rarely comes out." Matsuda stated.

"What's with her to you anyways?" All three soon turned towards the pinkette in curiosity.

"It's nothing... I just felt something wrong or ominous when she's around."

"I can't say that I'm surprised either... Her aura is definitely strong and... ... arousing." Motohama drooled which only made the other boys to look at him in disgust.

"Anyway, thanks for the unwanted information, I'll just have to get my own food..."

"Ah, Natsu... Would you also buy me some food? Sorry but I have a schedule running up this lunch with Matsuda and Motohama so..." Issei pleaded.

"Alright... I don't mind... Just don't get killed, Issei... There are more things valuable than oppais." Natsu advised though he guessed that it won't engrave right inside his brother's mind like that easily, seeing his strong perverted nature.

Leaving that aside, Natsu simply glanced around and turned to the other direction before disappearing into a corner before going downstairs and lined up with the other students who were also waiting in line for the order of food. It didn't take a few minutes for his turn as he took out a simple meal from the cafeteria along with some drinks for himself before settling himself towards the edge of the table in the far corner and started eating.

This is the only time he would gladly enjoy his time during school. Eating without any interruptions is almost heaven to him. He didn't care getting any peers at the moment. He'd rather wanted to be left alone and deal with his own problems without any care in his surroundings, including people. It's one of the reason of why he was one of the neglected students in the campus with a bad reputation yet he didn't care.

He was content with the life he had right now. A normal family and a slightly... perverted brother is enough... Slightly was such an understatement though.

..

..

After eating, Natsu ordered a handful of snacks for Issei and started to return back towards the room but stopped afterwards, seeing the bell range right before he could even enter. Thinking for a moment, Natsu pondered about going in or not. After experiencing of the lazy staring at the teacher on class, he might have to choose not to and skip the class and rest somewhere else.

Taking a step away from the classroom doors, Natsu walked upstairs and eventually turned to settle down on the rooftop to clear his mind there. With the food still on his hands, Natsu placed it right at the ledge and decided to also lie himself there, facing the bright sky.

A warm breeze of wind swept past through him, giving his body a soft and comfortable feeling to ease his troubles. In an instant, a wave of drowsiness came back like a flash as his eyes immediately closed and rested once more throughout the day.

Unknown to him, a white-haired figure is seen standing right below the school grounds, gazing above the rooftop and stared stoically at the sleeping figure before turning her attention back to the old building in secret.

..

A few hours passed and the sound of the last bell rang as the school was finally over. Natsu woke up just right after the last ring and started going downstairs and went to his room. After reaching the room, he found it empty, leaving only his bag slung on the side of his chair. Quickly grabbing it, Natsu made his way right away and intended to forget the detention as he went straightly towards the gate in which he saw a familiar figure waiting for him.

"Yo! Issei!" He waved before finally catching up to him and it was not before long he was smacked to the head by the brown-haired boy with an annoyed look.

"Where the hell have you been?! I was so hungry throughout the class and have been holding it up ever since!"

"Sorry... I skipped but I bought your food." Natsu apologized before giving him the food he order earlier, much to his delight.

"Thought so... It's not so uncommon for a potential delinquent like you."

"I'm not delinquent..." Natsu reasoned.

"You're turning into one if you didn't stop that bad habit of yours." Issei reminded.

"Class is boring... I'm surprised that you and the others were able to cope up with it."

"You're making it seem like you're not human, Natsu." Issei sighed.

"Is that so? Everyone has their ups and downs but this one is not for me, you know..."

"I know... Anyways, we better head back... Mom and Dad are probably worried."

"Seems like it..." And with that, the two simply walked their way towards the street as the sun sets towards the western horizons before darkness slowly crept its way on the other side of the globe, signifying the end of the day.

It didn't take them long enough to reach to their home as both of them entered and left their shoes just by the entrance and went to the kitchen to greet their parents who were patiently waiting for them to come back.

"We're home!"

"Ah, welcome back, you two... How's school?" Their mother asked.

"We're good." Natsu lied though Issei simply went along with him for the sake of not worrying them.

"I'm glad... but we're having dinner so be sure to come downstairs, okay?" The two brothers nodded in response before turning over towards the staircase and went to their separate rooms as Natsu carelessly dropped his bag and crashed on the bed, seemingly tired as he glanced sideways, thinking about the recurring dream earlier in his class.

Although it might seem unusual to remember as mysterious as that, he felt that it had to do something about his past. Apparently, he doesn't have anything to remind him of that past except for his name. Despite being adopted to the Hyoudou family, they permitted him to retain his original name instead of replacing it in honor of his past.

It's already been years since that happened and he moved on along with the life of being together with his newfound family. Delving right into the past with nothing to prove or make him remember is simply useless to do so.

A knock soon came out from his door as Issei's voice soon resounded over to the walls.

"Natsu... Dinner's ready... Mom asked me to fetch you downstairs."

"I'm quite full... Eat without me." There was no response for a moment until he heard him finally gave up and went downstairs to eat along with their parents.

The darkened room was accompanied with the faint illuminating light of the moon just beside his window as a small gust went inside, causing the curtains to move and revealed much of the outside world to him as he saw the clear sky with the moon being the center of the background, prompting him to gaze at it momentarily before heavy wave of drowsiness came about and overwhelmed his body and eventually succumbed to the slumber.

He had a feeling that he might experience the same dream once more.

"Are you sure about this?" A female voice was soon heard from behind the darkened room, masking her presence towards the other female who was standing still at the open window, facing the bright moon illuminating the night sky as her crimson hair reflected back to its light.

"I cannot be right all the time, Akeno... That's why I'm having you and Koneko to give surveillance to those two."

"And you want me to observe this person... I don't sense something inside of him so why would you want to give importance to him?" Akeno asked curiously from the shadows.

"Even without a Sacred Gear, you cannot expect me to just ignore all the other non-Sacred Gear users..." The female replied.

"I never said that, Buchou. But what I'm asking about is your decision for that boy... You were still confirming about the other one but this one is completely..." Akeno stopped for a moment to put a proper word for it.

"That boy is not special, alright. But I sense something rather different from what I've seen from the others so far."

"And you want to find out why?" Akeno clarified.

"Exactly... Although it might come as a stretch for our resources, it's worth a look... Plus, with him being related to the other boy, there's a chance that they might both possess the same results." The red-haired female smiled as she turned back from her gaze and into the shadows where Akeno was standing.

"Alright... I guess I should trust your intuition on this, Buchou..." Akeno reaffirmed.

"We should also make our move soon... The other factions are starting to move as well, especially the Fallen Angels."

"What are we going to do with them, Buchou?"

"For now, we should ignore them and be on alert, at the very least. They don't seem to make a move yet so we won't do so either. In the meantime, we should focus in the two."

"Of course..."

And with that, Akeno disappeared from the shadows, leaving the red-haired beauty to stare into the sky once more as the small wind blew past right in front of her, causing her hair to flow gracefully as time went further through the night.

..

..

"Things are really turning for better or worse. I should make a move soon."

A/N: Here's the prologue for you guys. Sorry for the long wait. As you can see, I tweaked Natsu affiliation by being an adopted brother from the Hyoudou residence in order to fit in with the crossover. Originally, I was intending to replace Issei with Natsu but after thinking about it for quite some time, I decided to keep them both together.

Of course, there's the question of harem... There's no denial of a harem here so I'll just post a poll about the separate harems for the two if you're fine with that. It's up to you readers if you want Natsu to hog all the girls but you're leaving Issei out of character but it's your choice. My decision of the girl chosen for Natsu and Issei are still unknown so a poll and opinions from readers would also help.

On the side note, this will be also receiving rarely updates just like the other two recently posted stories. I had to post this in order to prevent from total forgetfulness of the plot.

That's all for now.. Feel free to PM me for questions about the story and I'll try to reply as soon as I can.
