Disclaimer: Don't own anything named Fairy Tail…except Kuro Tenebris!

Normal speaking: "Why hello there."

Normal thinking: "This guy's pretty good."

Demon or higher being speaking: "I will crush you!"

Demon or higher being thinking: "Wonder who I'll have for dinner..."

A young boy ran through the dark forest, hands over his head so it wouldn't get hurt or any wetter than it already was due to the rain. He had to get away. He cursed as he cut his leg. He kneeled and cursed again before a roar could be heard from behind him. He looked back…a flash of lightning was all he needed as it provided enough light to see two red orbs glaring at him. He screamed and starting running away.

It was amazing what adrenaline did to the body. It numbed any pain and it also kept you going. Fighting or in this case, running. He slid under a tree before running again. He felt so grateful at his mother for drilling those parkour lessons into his skull. Now they were like second nature. He looked to the left. A large tree with many leaves as right next to him. He thought for a bit before running again. He stopped suddenly and retraced his steps before climbing the tree with ease.

Now all he had to do was wait for the demonic being to pass by and he could rest easy. The demon showed up after a few minutes. He was lucky that all the mud and rain masked his scent. He was pretty sure that the monster could smell him. The being tilted his head before running forward, following the footsteps. A flash of lightning was present once again.

The ten year olld boy sighed as the demon was out of sight. He looked down as tears fell from his eyes.

Why did it have to happen?

Why?

His mother didn't do anything wrong dammit!

His father was never present to begin with…it was his damn fault for not being there to protect her and him.

He sighed again before he fell to sleep.

Morning came and with it the boy woke up finding himself stuck to the tree. The mud that was on him dried up and he was stuck now. He groaned and shook himself.

Good news, he wasn't stuck anymore.

Bad news, he fell down.

He groaned again as he got up, thankful for not breaking anything. He looked back from where he ran away from and frowned. He shook his head and went back.

He wasn't going to let his mother's death go unpunished, he was going to get stronger, find the demon bastard and kill him.

He entered his house with a heavy look on his face. He ignored the mutilated remains of his mother as best as he could and went to the family portrait. He tore the large portrait off the wall and grabbed what was inside the hole in the wall there.

A katana giving off an ominous red glow with black trails of smoke coming out of it.

"That sword was passed down from generation to generation in our family. No one could ever use it though, said to be possessed."

His mother's words rang through his head. He shook his head and grabbed the sword with a determined look on his face.

He was immediately plunged into a dark mansion.

"Well, well, well. Look what the thirst for revenge dragged in!...that sounded so much better in my head." A voice echoed from around him.

"W-Who are you?" he asked.

"Wow. The way you ran away from that demon guy made you seem like a little coward. But now you seem like a little idiot." The voice cackled.

"…" the boy remained silent.

"The calm, cool and collected type huh? Okay kid." A tall teenager with scaly black skin, large bat like wings and long tail appeared in front of him. Between the black scales there was a red glow that dimmed and brightened with the beat of the teenager's heart "As for who I am well…I, am Kira." he bowed mockingly, his long hair falling down before he got up "Save the autographs for later." He grinned cockily.

"Kira?"

Kira's grin grew larger if possible "The most powerful devil in existence, stronger than even anything made by that bastard Zeref." His grin turned sadistic "So. You must really want revenge." Kira began circling around him.

"Huh?" Kira unnerved him.

"Why else would you grab my so called prison?" he asked before putting his face mere inches away from the boy's.

"Y-Yeah. I need your help!" he said.

"…Meh. I'll help. Got nothing better to do as it is. Seeing you struggle would be fun."

"You'll really help?"

"Yep. Now get outta here! I'll establish a permanent mind link so we can keep in touch!" he waved before Kuro woke up with a startle. He looked at his left hand suddenly, it held the katana but it was also changed. It was completely black with a red dragon circling it. The dragon's head was on the back of his hand and its eyes seemed to glow black. He stopped staring at it and got up.

"You're probably wondering what's the deal with your left arm."

"Who said that?!" he yelled and looked around.

"Sheesh, relax kid. Permanent mind link is permanent!"

"Oh right…sorry,"

"Whatever. The tattoo is basically my influence on you I guess. As long as you have that left arm I'll stick around, giving you advice and what not." He could feel Kira shrug.

"Thank you."

Kira chuckled "Oh don't thank me. By the end of our training you'll be hating me. Welcome to your tortu-training!"

The boy gulped.

Six years have passed since then.

"Stop that thief!" a man yelled as a boy ran away from him, bread in his mouth and apple in hand. He found himself face to face with a group of men cutting his way off. He smirked behind the bread and turned towards an alley. The man followed but the boy was agile. He started to tic-tac up the walls before he eventually climbed to the top of a building. He pulled himself up with his left hand and gave the men below him a two finger salute.

"Argh…get him!" one yelled and everyone started running up the stairs. The boy kept running, vaulting over some objects and sliding under others. He looked behind him, the men were catching up. He frowned and started balancing on a cable leading to a different building. He was halfway before he heard another yell "Cut the cable!" He looked behind and a man crouched down with a knife in hand. The boy grimaced as the man cut the cable. He grabbed it and swung into an apartment through the window.

"AAAAAAAAAHHH!" a woman yelled as he rolled through the fall and out of the door. He quickly ran up the stairs. He found himself on the roof in mere seconds. He smirked before he heard rapid footsteps. He grunted and ran.

"You're enjoying this too much."

"Yeah I am." He smirked before gulping down the last of the bread. He stopped suddenly as he reached the ledge of the house roof. He looked down below, he couldn't climb down quickly.

"End of the line kid. Now how about just giving back what you stole and accepting your punishment." A man slammed his club in his hand with a smirk on his face. The boy looked as if he thought for a bit. He looked behind him and inched backwards a bit.

"Hey now, don't do anything stupid kid." A different man said hurriedly. He didn't want a kid to die just because he had to steal.

"…" the boy smirked before throwing the apple to the people and leaning off. As he fell he gave them another two finger salute. The men there went over to the edge and saw the kid laying on a carriage while eating a red apple from the pile next to his head with a smirk on his face.

"Damn brat!" a man yelled as the carriage was dragged away by the horses. He got off in the next town. He stretched a bit before looking around.

The town he was in was bustling with activity. People were doing their jobs, mages were off on their requests and children were playing. He sighed.

"It ain't gonna help if you dwell on it kid. The best thing you can do is move forward."

"I know."

A massive slam shook the earth.

"The heck?"

"It came from the mountain. You should check it out, get some more experience kid."

He nodded and started running towards the mountain.

Why did she take this job?

That question kept plaguing her mind.

If she just swallowed her pride and refuse this job then she wouldn't have her arm broken and her sister be put in danger.

Their brother stood in his beastly form above Lisanna.

"Let's go home, Elf-niichan." The younger sibling smiled before she was brutally slammed away.

"LISANNA!" she yelled before the dust settled. She widened her eyes.

A boy clad in a black coat with a grey shirt and dark blue pants along combat boots of the same color blocked the strike with his sheathed katana.

"Tch." He frowned before throwing the beast away "You two okay?" he asked without looking "If so, then run away." He prepared to draw his sword.

"Wait, don't hurt him! He's our brother!" Lisanna yelled.

"Eh?"

"Wow. Didn't see that one coming. He must be using take-over magic but got taken over by the beast instead."

"I'll just knock him unconscious."

"Any ideas how Kira?"

"First you got to grab him by the horns…"

He shrugged before he advanced forward. He sidestepped a blow before climbing on the arm and staying there. He impaled his sword in the arm, making the beast roar before trying to shake him off. He smirked and held on before his opponent raised his arm in the air. He let go and was sent flying into the air.

The boy smirked before bullet diving towards the giant monster. As he was about to strike, he leaned to the left and dodged the punch. He sent out a burst of dark energy out of his left arm, propelling him to the right before he grabbed the horns of the beast…

"And slam him into the ground. That's how you'd take him out without killing him and in a stylish way too!"

…and, using the incredible momentum from the drop, dragged the whole body of the beast with him into the ground where he slammed it with a giant crash. He sighed and dusted himself off before grabbing his katana and pulling it out. The giant body soon transformed into a tall man.

"Elf-niichan!" Lisanna said and hurried to him.

"He'll be fine. Just bandage the head and his arm." The boy shrugged before he went to walk away.

"Wait!" the older girl stopped him "Who are you?"

"…Kuro Tenebris. What of it?" he asked with his head tilted towards her.

"Why did you help us?" she narrowed her eyes.

"Did I need a reason?" he asked and raised an eyebrow.

"You don't look like the type that just helps people out of the blue!" she yelled and pointed at him.

"Ouch. She's got a point kid."

"Mira-nee!" Lisanna yelled before turning to Kuro "You'll have to excuse her. It's nothing personal, she's like that with everyone."

"Lisanna!" she whined before glaring at Kuro "So what do you want?"

"Nothing." He shrugged and walked away. He stopped suddenly "…Actually. I could use some help with directions. Mind telling me where Fairy Tail is? The guild?"

"Why?"

"I want to join." He shrugged.

"The fastest way to get stronger is to join a guild. Lots of tough opponents can be found in those jobs of theirs. If you are going to fight a lot, you might as well get paid…and I heard that there are a lot of hot babes."

Kira said that around their first year of training. He looked for a guild for quite a while but never found one that fits. Fairy Tail seemed to be the best one.

"Yeah we can show you. We're members of it actually!" Lisanna smiled as she worked on her brother "Can you help Mira-nee with her injuries?" she asked.

He sighed and went to the girl. He looked her over. Broken arm, twisted ankle and dozens of bruises and cuts. He got on his knees and extended his arm.

"What are you doing?" she asked with a glare.

"Your sister asked me to help you. That's what I'm doing." He kept his hand extended. She sighed and put her right foot there.

He couldn't help but notice how soft her skin was and despite the many injuries it was flawless.

"Looks like lil'Kuro has his first crush~ I approve kid. She's hot!" Kira laughed from his mindscape. He blushed lightly before shaking his head to clear the improper thoughts.

Mira glared at him before he roughly twisted her ankle back in place. There was a crack and he smirked. The bone was set back reasonably well. All she had to do was not put stress on it and it will heal with time.

She hissed in pain before he went over to her left arm. He touched it a bit, seeking the broken segment and noting the skin was as soft as her foot and leg. He found the broken bone and winced a bit, that was going to take a while to heal without magic. He sighed and got up before going towards a nearby tree. Cutting a branch and making a make-shift splint. He put it near her arm and fished around for something in his coat's pocket. He took out a couple of bandages before he tied her arm up.

Mira had to admit, he was good at this and fighting as well. She already felt better and the make-shift splint didn't feel wrong any bit.

"…" she muttered something as he got up.

"What?" he raised an eyebrow.

"I said thanks!" she yelled at him with a glare. He helped her up and she winced, her ankle still hurt.

"Lean on your sister." He said "I'll carry your brother." He went over to Lisanna "What are your names anyway?" he asked before picking Elfman up with relative ease.

"I'm Mirajane Strauss, she's Lisanna and the guy you're carrying is our brother Elfman." He nodded in acknowledgement before going to the train station near the town.

The three Strauss siblings were in a compartment with Elfman sleeping on two of the seats there. Kuro was in the hallway watching the scenery go by while leaning on the window.

"So, what do you think about him Mira-nee?" Lisanna smiled with a certain glint in her eyes.

"W-What are you talking about?" Mira looked away.

"Just wanted to know what you think about him." She shrugged.

"…He's good at fighting and patching people up." She said eventually "Though I never saw anyone with magic like his."

"Maybe he's like Natsu and uses Lost Magic." Lisanna offered.

"Maybe." She looked at the boy. He had unruly black hair with a single strand sticking up. His eyes were a cold blue on his heart-shaped face. He had the body of a seasoned runner and was quite tall. Taller than her by around a quarter of a head.

Her gaze was drawn to his left hand. It was covered up completely by a black leather glove and bandages if she saw it right. What could he be hiding?

She sighed and got up "I'm gonna go talk to him." She exited the compartment.

Lisanna giggled to herself. Her sister definitely liked the black haired boy.

"Hey Kira?"

"What is it kid?"

"I don't say it too often but thanks…for everything."

"Don't you go all mushy on me kid." Kira growled but smiled and chuckled afterwards "Just did what any diabolical, psycho demon would do. Just make sure not to forget."

"That things have a way of working out? I know. That's why I'm not looking for that demon bastard. I have a feeling he'll be looking for me."

A hand on his shoulder snapped him out of the conversation with Kira.

"What is it?" he looked at Mirajane with a deadpan expression.

"Hey look, I was kind of a piece of shit when you helped us and I'd like to apologize." She looked out the window.

He chuckled.

"What's so funny?" she glared.

"Didn't take you for the kind of girl to apologize." He chuckled again "Apology accepted." He shrugged and kept looking out the window.

"So, what kind of magic do you use?" She asked suddenly.

"…" he thought for a bit "A form of darkness magic." He shrugged "I found this sword and now I use its magic." He looked at her "What about you? Take-over?"

"How'd you know?"

"Just a hunch. Figured your brother was using Take-over so I thought you two were using it as well."

"Yeah. We all use Take-over."

"Which branch?"

"…Satan-soul." She said while looking away. She knew her magic was frowned upon. She did turn into a demon after all. Heh, who's to say he won't join the guild now?

"Interesting." He nodded before everything was quiet.

The rest of the ride was made in blissful silence.

"Well here we are, the Fairy Tail guild." Lisanna proudly proclaimed before she and Mira opened the doors "We're back!" she smiled and everyone looked at them.

What happened to them?

"Lisanna! Are you alright? What happened to Mira and Elfman? Who's that guy?!" a pink haired boy assaulted the white haired girl with questions.

"I'm fine Natsu, It's a long story but he saved us and wants to join the guild." She pointed at the black haired boy carrying Elfman.

"So I guess that was all bark and no bite eh Mira?" an armored girl smirked.

"Shut it Tin-can! I can still beat your ass!" she growled as everyone laughed.

The master of the guild went up to Kuro and asked "Who are you boy?"

"Kuro Tenebris." He said simply before setting Elfman down on a table "I want to join this guild. I heard some good things about it."

"Where do you want your stamp?"

"The back of my right hand, in black."

The old man pressed the stamp on it and after a few seconds the Fairy Tail guild mark appeared.

"Why do you want to join anyway?"

"To kill someone."

The old man glared at him, unleashing his magic power and creating quakes while putting an insane amount of pressure on Kuro.

"This is insane! Are all guild mages this strong?"

"Holy crap! Abandon ship! Mayday, mayday! The old man is too strong!" Kira yelled in his mind.

"Kill who?"the old man asked with a much deeper voice.

"It's a demon." The magic power faded and the pressure was gone along with it "It did something horrible to my mother and I want revenge." Kuro continued.

"Well then as long as you won't bring harm to the guild, then you can join!" the old man smiled "I'm Makarov Dreyar and welcome to Fairy Tail."

Everyone cheered at their new member before a massive brawl erupted. Chairs, tables, bottles and even people were flying and crashing around.

Kuro watched in disbelief.

"What have I gotten myself into?"

"They are crazy…This is my kind of place!" Kira laughed.

The boy sighed before sitting at a table with that red haired girl from before. She wasn't taking part in the brawl so he assumed she was normal.

"Is this a normal occurrence?" he asked.

"Yes. They are complete fools. This is a guild not a place for fighting. I'm Erza Scarlet by the way." She extended her arm for a handshake.

The two shook hands before a guy was thrown into Erza's strawberry cake.

Kuro blinked and Erza was gone. He looked to the right and there she was, in the middle of the brawl already beating two boys up.

"Now that girl…is scary as hell."

"Agreed."

He heard a scoff from above him and everyone stopped to look at the source. He looked up and saw a blond man.

"So you're the new guy huh?" the man vanished in a strike of lightning before appearing in the same fashion on the seat beyond him "Wasn't aware Fairy Tail was recruiting weak members." He smirked.

"This guy is an idiot, kid. Beat his ass for me!"

"Then what are you doing here?" he asked with a smirk of his own. The guy scowled before chuckling.

"You got guts kid but guts ain't gonna help you when I beat you!" he growled before sending a punch towards Kuro. The punch hit, creating a dust cloud "Too weak." The man smirked.

"I almost didn't see that one coming." Kuro smirked as he sat on the balcony of the second floor "Got anything else up your sleeve, kid?" he mocked and twirled his sheathed katana around.

Makarov narrowed his eyes at that katana. It was very familiar. Where did he hear about it?

Natsu and Gray looked up at Kuro. That was awesome!

Erza and Mira couldn't believe that Kuro could be so fast. No human was that fast!

"What's the matter?" Kuro cooed "Cat got your tongue?" he tsked and got up standing on the ledge with impeccable balance "So are we going to fight or what?"

The man dashed behind him before hitting him into the ground.

"Ouch. Didn't see that one coming did you?"

"I thought you were supposed to be on my side."

"I am…though you know me. I like to make fun of you! By the way, dodge."

Kuro didn't need to be told that twice. He rolled out of the way before turning around.

"You should really respect those stronger than you, brat."

"When you see someone, let me know." He smirked and dodged a flying electrified kick by leaning backwards. The man disappeared suddenly before Kuro was struck, then again, and again and again.

"C'mon kid. Focus dammit!"

Kuro closed his eyes and expanded his other senses.

"He uses electricity right? Well lightning is faster than him. He just uses it as a medium. So wait for that distortion of air, feel your hair stand up and strike where he'll appear before he even thinks about it!"

Kuro smirked before hitting the man with his sheathed sword into a wall, destroying the poor structure in the process.

Makarov did a double take at that. He predicted where Laxus would appear? That took incredible concentration to pull off when you could see your opponent. But that Kuro boy did so with Laxus! Was he some sort of genius?

Kuro opened his eyes before cracking his neck. Lightning struck the location where the man was.

"I've had just about enough of this!" Laxus growled before charging up for a spell.

Kuro smirked before preparing to draw his sword. Black smoke covered him and the surrounding area as a red glow came from the blade "All will die before me..." Kuro muttered the small incantation of the blade.

Makarov's eyes widened. That blade was-

"Muramasa Sword Technique: Wicked Slash!" he yelled and dashed forward, becoming a black and red blur.

"Raging Bolt!" Laxus roared and sent his lightning towards Kuro. The guild master stopped them. He parried the lightning with his light magic and threw Kuro upwards. The black haired man found himself stuck into the ceiling with his katana there.

"There was no doubt about it, that sword is the Muramasa blade. That's why his name is so familiar. The Tenebris house had that sword in their family for centuries!"

"That looked more intense than a simple test of strength you two." Makarov berated them "We may fight from time to time but that doesn't mean we would kill any one of ours."

Kuro grunted before taking his sword out of the ceiling and gracefully dropping down. He sheathed his sword and scoffed. He absolutely hated when his fights would be interrupted "Tell that to him." He nodded towards Laxus "He's the one who started it. I just defended myself."

"That last attack didn't seem like defending to me." Makarov glared.

"Hey master, don't you think you're a little harsh here?" Mira stepped up "I mean yeah Kuro could have toned it down a bit but Laxus was the one who started it."

"And he will be punished for it. I was merely trying to get my point across. No more serious fighting from now on."

Laxus looked up at the ceiling and saw the single small cut that Kuro made there. He smirked and got up before dusting himself. He chuckled.

"What's so funny?" Kuro raised an eyebrow.

"I've seen what I needed to see. You're weaker than anyone here!" he laughed before teleporting outside the guild.

His smirk was still present as he started walking away. A wooden plank fell and he turned around.

He widened his eyes.

He couldn't believe this.

The whole of the rooftop was completely decimated.

He clenched his fist.

That attack…would have killed him if it hit.

"Kuro Tenebris huh…that guy might be a problem in the future."

"He wasn't fighting at full strength." Kuro nodded.

"That much was obvious. I think I'm going to like it here." Kuro smirked before calming himself down.

A couple of minutes passed and everything was back to normal.

"Yo Kuro!" the pink haired kid yelled "Come on over!" he grinned.

Kuro tilted his head in confusion before going to the kid "What is it?"

"That was really cool! We gotta fight sometimes!"

"Aye! Though Natsu'll probably lose!" The flying cat teased his friend.

"Uhh, kid you might want to have your eyes checked out. Last time I checked, cats don't fly…and talk."

"Shut up Happy!" Natsu yelled at the cat.

"Seriously flame-brain? Bothering the new guy already?" a black haired boy came up and extended his hand for Kuro to shake "I'm Gray Fullbuster, don't mind that guy, he doesn't think. His magic must have burned his brain into charcoal." He smirked as Kuro and he shook hands.

"Why in the holy hell is he naked?!"

"Just ignore these things Kira. I have a feeling that everyone here is quirky."

"You wanna fight Stripper?"

"Bring it on Matchstick!"

"Ahem." Erza coughed and the two were instantly nervous.

"So she's like some kind of enforcer around here?" he asked with a chuckle.

"Yeah, she's scarier than a monster." Happy whispered "You should see her on a bad day. Usually Natsu and Gray act like best buddies then." The cat laughed.

"Yo new guy!" a brown haired girl yelled from the bar "Think you can hold your liquor?"

"Not today." He shrugged.

"Well whenever you want to share a drink you let me know! Name's Cana by the way. Cana Alberano."

He nodded before he got up "I should go. I need to find a place to stay anyway."

"Bye Kuro!" Natsu grinned as he left the guild.

As Kuro searched for an apartment at this late hour he was unaware of the pair of black eyes watching him "Kuro Tenebris…perhaps you will be strong enough to finish what he started." The figure vanished into black dust before evaporating in air.

The young man eventually found an apartment for himself. He only needed to pay sixty thousand jewels each month as rent but it was well worth it. The apartment was spacious with a kitchen and two rooms along with a large bath. He shrugged and went to bed soon after.

One thing was for sure, nothing would be the same after he joined Fairy Tail. Everything was about to change and unbeknownst to him, he was going to be at the center of that change.

…

…

…

…

"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHH!" The screams of the guild master might as well have woken up the entire country. His screams of 'Money!' and 'Not another one!' pierced the serene silence that usually engulfed the night.

He smirked before looking out the window one last time. The stars were bright and the moon was full.

It was a beautiful sight to behold.

And it unnerved him.

There was something ominous out there.

He could feel it.

He yawned and shook his head. No reason to worry about that now.

In the streets of a city a woman was running for her life. She cursed as she ran right into a dead end. She turned around. Maybe she had enough time to escape!

The growls from the exit proved otherwise. She shuddered and closed her eyes before the creature pounced on her. She screamed just once as the thing tore her body and ate her very being.

"HUNGER!" the thing roared in the night and ran on all fours to find its next victim.

Chapter preview:

"A new mission just came in."

"So?"

"I want you to come with me. I'd like to evaluate your skills further."

"So what's this mission?"

"A series of murders in a city called Wolf's Den."

"Where were you on the night of the murder?"

"I DON'T KNOW!"

"Things just a got a whole lot more furry, kid."
