ARRANCAR – A Bleach Story

A/N :

Hey guys Mamikalp's here or MaouSatan or Almighty Acnologia, yeah all of these nicks are mine :)

My character's name is Natsu but this story is not a Xover in my opinion. The story was needing ONLY ONE OC and I decided to use someone I'm familiar with. (Yeah, I wrote FT fanfictions) Woops, I have to warn you he is not the same Natsu, his personality and body structure are different (He is an Arrancar for god's sake, you can't expect him to walk around grinning)

In this story there is no causeless power ups, especially for Natsu. He is not THE STRONGEST BEING IN THE WORLD or something like that, he is just trying to get stronger to take back his only reason for living. The story begins six years ago so he has enough time to train his skills.

Attention : This story contains emotional parts.

Evolution Arc – Part I

1995 – The year Masaki Kurosaki died

Karakura Town, Midnight

.

The town was quiet, sleeping in darkness. Several traffic lights were trying to illuminate the town but they were obviously not enough. The weather was cloudy, dark grey rain clouds. A group of teens were walking in a random street, they were drunk and talking about everything… and probably nothing. After a few foolish joke, something unexpected happened, a black line appeared one meter above from the ground with a strange tearing sound. It forced the atmosphere open like a window, a sinister, black window… Garganta.

Mere humans couldn't see the Garganta but the uneasy sensation was enough to make them run away.

Soon, a figure fell from the pure darkness like someone kicked him out. He fell to the ground face down and groaned in pain. He pushed himself from the ground hardly and managed to turn his body around, he was lying on his back now. He was a lean – built young man with pink messy hair who looked like 19 or 20 at most. He wasn't wearing anything except torn white pants, so his bare (a bit muscular) chest was exposed.

Based on this description, he was just a destitute man who is suffering in hunger. But the situation wasn't that simple. Left side of his face was covered with a HOLLOW mask and there was a large hole where his heart should be; left side of his sternum. The source was the hole in his chest, hollow matter was creating in there. Without a doubt, a soul was turning into a hollow maybe more… an Arrancar.

The mask was alive, it was trying to spread(devour) on his face like cancer cells. Unlike the other Arrancars it was polished jet black and demon-like, there was no hint of white in that mask. No mouth gap, just small narrowed eyes and pale-yellow vertical flame pattern.

Suddenly pink-haired boy's eyes snapped open and revealed his obsidian orbs, actually one of them because the other one was hiding behind the mask.

"What the?!" He felt the weight on his face and caught the mask immediatly. He tried the get rid of that but it was already attached his body like an organ. He tried to seperate it but when he couldn't feel any power in his arm he gave up, the mask calmly continued its job.

He sat on the ground and looked at an invisible object with dull, lifeless eyes. He was completely lost. He couldn't remember anything for a second, why was he here? Why there was a hollow mask on his face, wait what was a Hollow? And Why-

His eyes widened when the only thing he could remember hit his brain like a meteor. He turned around with all of his might and placed his hands on the ground just before a disgusting liquid left his mouth. Yes when he remembered THAT scene, he vomitted. Pale orange liquid flowed to the ground and splashed around. He looked at the ground, frozen. His pupils trembled in terror.

After a second, some kind of wet circles began to appear on the ground. He didn't make a move, it was raining and the mask was doing its best to cover his face. His entire body soaked under the rain but the rain couldn't hide the tears rolling down his cheeks and mixing the other drops. Finally he couldn't keep it inside, he trew his head back and screamed to heavens.

"AAAAAAAAAAAAAAA!" a never ending scream.

The hole in his chest wasn't hurting him, the brutal creature on his face wasn't hurting him… at least they were nothing compared to the real pain he was feeling. Like, someone was trying to shred his body apart and stabbing his non-exist heart. He turned his face to the ground and let the tears fell when his thoat began to hurt.

"I couldn't do anything…" He sobbed when the scenes of his previous life flashed before his eyes. He punched the ground.

"I couldn't do any DAMN THING!" He punched again but he wasn't aware of the piece of glass on the ground. It was cutting his hand. Despair and sadnees filled him, actually they accelereted the hollowfication. He sent another hard punch to the ground and caused his hand to bleed more but the tears were flowing faster than the blood. He sobbed again.

"He… did THAT to her right before my eyes." He couldn't say the word, he couldn't use 'her' and that indecent word in one sentence. She was too valuable for him to make a sentence like that. THAT scene came to his brain again and forced him to puke. He slammed his head to the ground and hoped that pain would go away.

Not gonna happen.

He hit his head again and again but nothing happened. His muscles were sore and his body was burning. He couldn't stop his body trembling in terror, in chaos, in fury…

He slammed his head on the ground one more time and let the mud dirt his face. He panted heavily and waited there without a move.

After seconds, he suddenly straightened his body and opened his eyes. He tilted his face and saw his reflection on the glass but it wasn't him, it was a horned demon. Scary enough to make an ordinary human faint. He didn't care about that anymore, he was looking for something else. He moved his face a bit and noticed a katana lying on the ground.

'Zanpakuto.' He thought althought he didn't know anything about that katana, he just… knew its name for some reason. He took the zanpakuto and pulled it out from the sheath. He held it in both of his hands and pointed the sharp side to his abdomen. Yes, he was going to do this. He took a deep breath and stabbed himself.

'I love you Natsu…' A soft but womanlike voice echoed in his head and reminded him the golden haired woman.

Fortunetely, he stopped the blade inches away from his body. He narrowered his eyes when the anger pressed the sadness down.

"What the HELL am I doing…" He hissed in anger and stabbed his zanpakuto to the ground. He grabbed the mask covering his face with both of his hands and tried to get rid of that again, this time… harshly.

"Gah!" He groaned as he felt an unbearable pain on his face. The mask was already glued on his face, it was tearing his skin when he was trying to pull the Hollow matter. Who cares. He didn't gave up this time, it was hurting him like hell but it just caused him to pull even stronger. He gritted his teeth too tightly, drew some blood.

There was no way he can forget her last words, he wasn't going to die that easily, not without suffering, not without revenge. Left side of his face began to bleed when he continued to pull. He didn't aware but, the air got heavier when he unconsciously unleashed his reiatsu. Nearest houses were effected from it too, the glasses were on the ground broken just like the flowerpots on the window edges. Blood flowed down his hands and soaked his arms.

He opened his jaw (almost tearing his cheeks) and roared to the heavens one last time.

"RAAAAAAAA!" One more time and he ripped the mask off completely, caused him to bleed even more. His arms fell to ground lifelessly and the reiatsu pressure disappeared. He just managed to sat like that, he couldn't even raise an arm. Everyone in the houses rushed to streets and wondered if it was an earthquake. Of course they couldn't see him, he wasn't a human anymore.

The scene was brutal, the skin on the left side of his face was mostly torn like he was attacked by a predator. He felt like he just seperated his ear from his body by pulling, the warm blood was dripping from his jaw to his legs. He couldn't scream, trembling of his body was telling the pain he was bearing. He did the unexpectable again. He slightly smirked and let the blood enter his mouth, the red liquid turned his smirk to a bloody one.

"I deserved this…" He whispered before he passed out. He didn't fall to ground just lost consciousness on his knees.

The certain pink haired boy stirred and slowly opened his eyes, strangely there was no pain in his body. He sensed the soft floor he was lying on, he was wearing a white kimono. He looked around and noticed that he is in a room but for some reason everything was yellow.

Soon he figured out the cube shaped yellow barrier surrrounding him, he straightened his body and sat. He turned his face to side then noticed a black haired little girl looking directly at him. Her cheeks were pink and there was a worried expression on her face, Natsu thought if she was worried about him but her expression didn't change for a while so he understood that her expression is permanent.

"How long I've been sleeping?" He asked before he placed a hand on his head. The girl stood up without the same expression, Natsu was right about that.

"One day, two hours, five minutes and 34 seconds." She replied with a monotone voice and walked away, the hollow just watched her leave with a suprised expression. After a few minutes, he heard something like 'What?' 'Really?'

He waited there without an emotion on his face. He looked at his reflection on the barrier, the wounds on his face was mostly gone. But his body was nothing like before, it felt more cold yet powerful. He was a hollow without any hollow matter covering his soul.

Meanwhile, the door opened and two figure stepped inside. One of them was a blonde man with a green hat on his head. The other one was a dark skinned muscular guy with a mustache. Blonde man approached to Natsu and hid his face with the fan in his palm.

"Oh my, he really is awake." He sat cross-legged in front of him when the others did the same. Natsu stared at the blonde man's face with a blank expression. The man narrowed his eyes a little then smirked.

"Sorry about that barrier, oh where are my manners… I am Urahara Kisuke owner of the Urahara Shop and these are my employees Tessai and Ururu." He said. Tessai raised a hand.

"Yo." And Ururu nodded her head.

"What's your name?" Urahara asked with a polite tone. The pink haired boy stared at them for a second then sighed in defeat, silence was pointless.

"Natsu." He replied simply. Urahara raised an eyebrow.

"No surname huh?" He asked and wondered if he didn't want to say his surname.

"I can't remember..." Natsu replied then raised his hands, looked at them like they were not his. Urahara looked directly in his obsidian eyes, it was so obvious that the boy was in pain. He changed the topic.

"Can you explain the hole in your chest Natsu-kun? It's like…" Urahara couldn't finish.

"Hollow." Natsu finished sharply. Urahara and the other ones were a bit suprised.

"So you know about Hollows and Shinigami, yes?" Urahara waited for his reply. Natsu ran a hand through his messy hair and tried to recall his missing memories.

"Yeah… I don't know how but I am aware of the basics. When I opened my eyes I was on the ground, figthing with hollow matter on my face" He replied. Urahara's eyes widened when he remembered what happened years ago, it was so similar. Just one name formed in his brain and made him narrow his eyes. 'Aizen.'

He took a deep breath and tried to calm himself then pointed the wounds on Natsu's face.

"How did you managed to get rid of the mask." He asked with curiosity. Natsu's answer was simple.

"I ripped it off."

Even Urahara couldn't hide his shock, Tessai frowned.

'What are you…' He thought. Urahara snapped.

"It's impossible, you can't stop the hollowfication like that. In your case it must have become your real skin." He said with a loud voice, didn't want to yell at him then hid his face behind his fan. On the other hand, Natsu was unfazed.

"Yeah, it hurt like hell." He pointed the wounds on his face with his index finger. Urahara's eyes widened, probably they found him a little late. Most of his wounds must have healed with high-speed regeneration, a natural hollow skill. He couldn't help but smirked.

'That boy…'

"So what are you going to do, if we release you?" Tessai decided to ask. Urahara looked at him then turned to Natsu again, he was going to ask the same thing. Natsu frown a bit, he looked at their faces. They weren't bad types at all.

"I…" He hesitated then decided to thrust them.

"Someone precious for me died at the same time with me. Her soul must be in that Soul Society place right?" He looked directly at Urahara, his obsidian eyes looking into his soul. Urahara felt a bit uneasy but he didn't complain.

"Oh my, sorry for you. For your question, probably… but there were other options. Human World or Heuco Mundo…" He replied, not sure if he said the best thing. He didn't say 'Hell' of course, he was too young to be hollow meal.

A disgusted expression covered Natsu's face, she wasn't in H.M right?

Pink haired Arrancar-like shook his head and turned his face to Urahara again.

"I'll find her." He said with a confident tone. Urahara stared at him with suspicious eyes, Natsu did the same. Either of them was not stepping back. After seconds Urahara sighed and gestured Tessai to let him go, the boy earned his trust. Tessai waited for a second then made a hand motion, lifted the barrier.

"Let's make a deal…" Kisuke's sound echoed, he approached to the boy without a fear and moved the fabric which was covering Natsu's hollow hole. Natsu was suprised but didn't make a move, allowed him to finish. Urahara noticed the black matter around the hole, trying to spread again. He was expecting this but why it was black?

"Deal?" Natsu asked in confusion. Urahara was a caught off guard but he recovered himself quickly. He forgot about the black matter, Aizen was really a dangerous human. He turned to the young man.

"Your actions didn't stop the hollowfication, I know who did this to you and probably it wasn't his real goal." He pointed at the black hollow matter and made Natsu look at there. Pinkie's eyes widened when he saw the same thing before. "You must be an unsuccesfull experiment."

Urahara didn't stop.

"I want you to stay here as an employee of mine. Of course you can search for your GIRLFRIEND when you are not working. As a salary I will give you…" He took a pillbox from his pocket. " ..this."

Natsu looked at the thing in Urahara's palm, he forgot about the experiment part for a second.

"What's that?" He asked. Urahara suddenly stood up and smirked.

"THIS IS MY ULTIMATE INVENTION SO FAR! HOLLOWFICATION BLOCKER!" He raised his arms to air in a 'I am a god.' motion. Everyone except Urahara sweatdropped.

"You're holding the wrong box Urahara…" Tessai deadpanned. Suddenly Urahara froze and read the name on the box. Aspirin. In a second he was sitting in the edge of the room, hugging his knees.

"I ruined the promotion again…" He said with a sad voice. Natsu felt the edge of his lips rising up, he felt heat in his abdomen. Soon, he couldn't hold it inside anymore.

"HAHAHAHAHAHAHA" He burst into laugher and caused everyone to look at himself. They watched a hollow laughing his ass out. It was short but he felt good for a few seconds. Natsu's eyes glowed in excitement as he turned his face to Urahara.

"So be it. I accept your offer Urahara Kisuke!"

.

That's all. Evolution Arc – Part II is ready but I'll wait for a while and edit the other chapters. There is no other OC character in this story so you can guess the woman Natsu is searching (I fell in love with her a while ago). Hope you enjoyed, don't forget to REVIEW it means a lot for me!

Psst, Little Ichigo in the next chapter...
