I own only my OC.

Rouki stood in the middle of a forest looking at his opponents. They stood with one to his front, two at his back and three at his right side. Each of them as big as a house.

"This is all you are? Insects? It looks like this is going to be more simple than I might have thought. But in all honesty why did they see this as an S-level threat?"

Indeed his opponents were insects. Giant beetle like insects with armored hides and whipping antennae. Each of their mandibles were snapping with what Rouki figured was their anatomical equivalent to saliva.

"I hope your exoskeletons are strong," Rouki said while unsheathing his sword. "Because my friend has had so little sturdy opposition to cut."

The insects screeched in reply as they charged him making the earth slightly rumble...

~ ~ ~ ~ Back at Fairy Tail ~ ~ ~ ~

"Sworn to kill us?"

"What the hell did we do?"

"Why do so many people want to kill US?"

These were only a few of the responses that suddenly were spouted when Makarov finished his sentence. Many of the members had wide eyed faces and open mouths. Some people were complaining that someone was trying to kill them again. Which was considerably understandable with Phantom Lord having done their deed.

"Quiet down and I'll give you your answers." Makarov stated to the small crowd now quieting down. "Rouki, as I said was a member of Fairy Tail. It was many years ago when you were all children and not even in the guild. Our older members will remember him though."

"Oh yeah, you don't forget someone like that kid." Macao said.

"Just think...if he was like that back then, just think of how he is now that he's all grown up." Warren shuddered at his thoughts of his words.

"Come on how bad of a guy could he have been if he was in Fairy Tail?" Lucy turned to the two older men as she asked her question. In response she received from the two a look that matched that of a person who were about to tell her a relative had died. "That bad huh?"

"Indeed, Rouki was a very...unique boy." Reedus spoke with a grim tone in his voice.

"Unique and powerful." Cana spoke as well.

"Powerful? How powerful?" came from a guild member.

"At age twelve we considered him one of our most powerful younger mages." Macao answered.

"He was that strong?" Lucy gasped along with many other guild members.

"Why didn't we know about him? Why did he leave the guild? Just what exactly happened to make him want to kill us all?"

"Master, we are all listening, please tell us about this man." Erza asked as she stepped to the front of the group. Makarov breathed in deep and let out a heavy sigh almost to prepare him for what he was going to say.

"I have every intention of doing so Erza, as such I will start at the beginning."

With that Makarov began his tale...

~~~~Years ago in Fairy Tail~~~~~

"Ah, another day passes on, and off to another good night's sleep." Makarov was just walking out of Fairy Tail as the moon was shining down on the town making it a beautiful night. As he was starting to make his way home, his walk was interrupted by a small voice.

"Are you Makarov, Guild Master of Fairy Tail?"

Makarov turned to see a small boy of what he guessed to be around twelve years old. He was wearing old ragged clothes with a hood covering his head. On his back was something wrapped in an old black cloth. In the moonlight his eyes slightly reflected a faint light. Makarov guessed that the boy must have had a very light eye color for his eyes to shine like that.

"What's a young boy like you doing out at this hour?" Makarov asked the boy.

"Please answer the question sir."

Makarov was taken aback by the seriousness in the the boy's voice as well as the respect by calling him sir.

"Yes I am, who are you?"

"My name is Rouki sir, and I request that I become part of your guild."

"Hmm? Oh, eh well you've caught me at a bad time I'm afraid, I've closed up the guild and I'm heading home for the night. But if you'd like to stop by the guild

tomorrow I'd be happy to talk to you."

The boy simply stared at him and replied with a simple "If you'd like." Then turned to walk away.

"Interesting boy." Makarov said turning back to walking home.

~ ~ ~ ~ The next day ~ ~ ~ ~

'click'

The locks holding Fairy Tail's doors closed were unlocked and Makarov grabbed the handles and opened them.

"Ah, another morning another new day."

"Good morning sir."

"Gah!"

Makarov grasped his chest as he turned around to see the child from last night.

"Oh, it's you. You startled me. I didn't expect you to be around this early. In fact, how did you know when I open the guild?"

"I stayed in the tree until you came back sir."

"Oh...so you did." Makarov sweat dropped slightly at the boy's words. "Well, come inside and we'll talk."

Makarov walked inside with Rouki behind him. When he turned to face the child he folded his arms.

"So my boy, what makes you want to be part of Fairy Tail?"

Rouki took off his hood to reveal his short strawberry blond hair.

"I would like to further my abilities as a mage sir. I already have a preferred magic and I would like to continue training myself in it."

"Oh, so is that the only reason?"

"Well sir..." Rouki looked down as if in embarrassment. "I would also like to make more friends."

Makarov smiled at this and walked behind the counter to open a drawer and pull out a small box.

"You know, I think you would be a welcome addition to the guild." Makarov opened the box and revealed the Fairy Tail guild stamp. "Where would you like to have your mark?"

"Here please sir." Rouki pulled back his left arm sleeve up to his shoulder and pointed to the underside of his forearm.

"Hmm." Makarov looked to where he wanted the guild symbol and stared intently at it. Along the underside were scars that lined many spots on his arm but they stopped before the reaching his wrist.

"Is there something wrong sir?" Rouki asked.

"Oh, no not at all." Makarov quickly patted the stamp onto Rouki's arm and made the mark. "There, now you are officially a member of the guild. So you know, here at Fairy Tail we treat our own as family, not just friends. So as long as you have that mark on you, you will always be welcome here and you will always be considered family." Makarov finished his words with a warm smile for the boy, happy to have a new addition to his guild.

"Thank you sir. Now if you will excuse me, I will start with the guild tasks." Rouki immediately walked over to the commission board. As he started to look at the papers Makarov made a suggestion.

"For someone your age, I suggest something small. That way you can build up from there. A step at a time."

"Yes..." Rouki said softly, "One...step...at a time." Rouki reached up and grabbed a paper that read 'Guard needed for estate- 200 jewel'"

"Yes I think that will do very well for you." Makarov said with a kind smile. He knew the family that commissioned the job and knew them to be rather worrisome when it came to their property and had a fear that children would vandalize it. So scaring away other kids and keeping them from throwing toilet paper into trees wouldn't be a big deal for Rouki.

"Thank you sir."

"Well then I think it's time to to start setting things up for our waitresses. The others will be here in a while so feel free to introduce yourself." Makarov said once again with a smile as he walked into the back of the guild.

When Makarov was gone Rouki looked back to the commission and took down two more papers. They read 'Subdue Bandits- 1,600 jewel' and 'Hunt Down Mountain Devils- 10,000 jewel.'

"These will make good steps and they'll probably take a few days. Are you ready?" Rouki looked over his shoulder as if there was someone behind him when he said this.

"That's what I wanted to hear."

Rouki turned and started to walk out of the building, pulling his hood over his head as he did so. The instant his feet touched the outside ground Rouki started running.

A while later Makarov came out and found Rouki gone. "I guess he went home, at least I hope he did. Wouldn't want to go into a mission unprepared."

"Good morning master!" Came the voice of Elfman as he entered with his sisters at his sides.

"Oh good morning!" Makarov said to the young siblings, "How are you three today?"

"I don't know about these two but I'm ready to get to business." Mirajane said as the walked to the commission board.

"Yep Mira is all fired up as always." Lisanna Said.

"Well don't worry Mirajane, we have quite a selection for you, bandit and Mountain Devil hunting commissions."

"Freaking sweet!" Mirajane looked around the board and found no such papers. "Hey! Where the hell are they?"

"Hmm? I set them near the bottom so they should be there." Makarov said when he walked over to the board. When he got to it he found both the papers were gone. "Oh no...he didn't take them did he?"

"What? Who? Who took my jobs?" Mirajane yelled.

"Oh, we have a new guild member but, I guess he left with the commissions." Makarov sighed when he realized what had happened. "That kid, he's gone way over his head."

"A newbie took my commissions? He better not come back or I'll kick his ass!" Mirajane yelled in her anger.

~~~~Three days later~~~

Makarov was going through the guild's mail at the moment. It had been three days since he had seen the newest member of Fairy Tail and Makarov was starting to get worried. What he didn't know was that his worries were about to be put to rest when he found a letter sent to him from the family that had put up the Estate Security commission. Makarov opened the letter and read it silently. As he read it his eyebrow raised. "Well I'll be." He said.

"What is it master? Bad news?" Wakaba asked from the table he was drinking at.

"No actually, we've merely received compliments for our services."

"Complements? What's that all about? We've never gotten any of those before." Macao also said.

"No but we may in the future now. Our newest member has made quite an impression. It says here that the security provided by him was beyond exceptional."

"The gutsy kid who took little Mira's jobs? How did he turn out?"

"It says he stood guard over the estate for an entire twenty four hours. Constantly patrolling and investigating any noise the client requested him too. Then when the job was done he assured the client that no one was ever trying to get into the estate in the first place, but was just the client's...and I quote 'Overactive paranoia that has been hastily removed.'"

"Well hey, the kid did a good job! He should get a pat on the back."

"But if the commission was to watch over the estate for twenty four hours, why hasn't he come back?" Makarov said aloud, not noticing a figure walking into the guild.

"Probably afraid of what Mirajane would do to him once she got her hands on him. Say master, what's the kid's name again?" Macao asked.

"My name is Rouki sir, and I didn't come back because I had other jobs to do."

Many heads turned to see something that made many eyes widen. Rouki was walking up to the counter that Makarov was sitting on and was dragging a considerably large sack behind him. When he reached the counter he let go of the sack's straps and looked to Makarov.

"This is the payment for the jobs I had performed. I took what I needed, you can have the rest."

"Rouki, what jobs did you take?" Makarov asked.

"These." Rouki said as he pulled out papers from his clothes. Makarov looked at them and saw that they were the commission papers for the subduing local caravan thieves, and for hunting the Mountain Devils.

"Rouki what were you thinking? These sort of missions are too dangerous for someone like you."

"No they aren't, I've done them and I'm fine." Rouki said in response.

"But Rouki you're too-"

"Hey!" A voice yelled behind Rouki and caught his attention. He turned to see a silver haired girl wearing a bow in her hair and dressed in gothic styled clothes walking up to him angrily. "You're the guy who took MY jobs aren't you?"

Rouki pulled back his hood and looked at her almost in a confused matter. "Your jobs? I didn't think that jobs could be marked as someone's specifically."

"They can't." Said a young boy with black hair.

"Shut it Gray!" Mirajane yelled at the said boy.

"Sister be nice!" said Lisanna.

"If they weren't really yours specifically then I don't think that I did anything wrong." Rouki said before he walked past her.

"Hey don't you walk away from me!" Mirajane shouted as she reached out to grab Rouki's shoulder but suddenly Rouki turned around and lashed out with something.

Mirajane jerked back as she felt a stinging on her stomach. She looked down and saw a small slash across her abdomen. She looked back up to see Rouki looking at her with wide eyes and lowered eyebrows, looking at her in a way that made him look like he was completely enraged at her. In his hand was what looked to be a piece of metal wrapped in cloth for a handle. It looked like it had been shattered at the tip.

"If you want to hurt me, THEN COME ON!" Rouki shouted. Mirajane had an angered scowl grow on her face in response.

"Fine, you want a fight I'll give you one, get ready for pain!"

"Stop both of you!" Mirajane and Rouki turned to see Makarov looking at both of them sternly. "You are the same members of this guild you shouldn't be fighting."

"Oh boy this speech." Said Gray from his seat.

"Usually this is reserved for you and Natsu, Gray but I guess it works on other people too." Cana said.

"He started it! Master he-"

"Mirajane, no commission is just one person's. Everyone in the guild has a right to the board, not just you."

"Humph." Mirajane crossed her arms and looked away.

"Rouki, I told you that you needed to take small steps first. Going on missions like these are dangerous." Makarov held up the commission papers as he said this, "Especially with such a small and near useless weapon like that." Makarov said motioning to the blade in Rouki's hand.

"It's not small, it's still growing. And it's not useless."

"All the same Rouki, think before you act. Mirajane can handle these jobs because she's proven herself to be able to."

Rouki closed his eyes and sighed before he reached behind him and sheathed the metal piece he had in his hand. Mirajane kept a strong gaze at him with a smirk on her face at the master's words.

"I'm a little tired right now, I'll be back tomorrow for another job." Rouki turned and walked out of the guild building without saying any more words. But in his mind he kept thinking one thing.

'I need better challenges.'

~ ~ ~ ~The next day~ ~ ~ ~

Rouki was sitting while reading a book and eating a sandwich. He looked to be deep into the book when he thought to himself 'Actively performing these maneuvers will make one's body physically memorize the actions. The more they are practiced, the more easily they can be done.' Rouki looked up from his book and to the commission board. 'Yes I know that, but how can I be put myself to the test when I have such menial tasks.'

Rouki thought back to remember how he fought the road roaming bandits, and how he hunted down the Mountain devils. The bandits were just men who threw around swords and axes blindly with no skill, the mountain devils turned out to be minor devils that were more annoying than deadly. He needed something that he could actually challenge himself with. He looked around until he noticed something upstairs. It was another commission board but it had fewer papers on it.

'Maybe that board has more worth while requests for me to try out.' Rouki thought as he got up to investigate. But before he could even set one foot on the stairs a giant hand blocked his way.

"Rouki, what are you doing?" Makarov asked from his seat at the counter.

"Master I was just going to see the jobs that are on the commission board upstairs, I haven't seen any of the jobs from that one."

"Yes for good reason. The second level is for the S-Class and more experienced mages in the guild, you do not fit into either of those categories."

"But master, I-"

"No buts, you're not experienced enough."

Rouki looked at Makarov for a while before saying "Yes Master." and walking back to the table he was at. Makarov noticed that he kept looking to the board on the second floor and back at the first floor board. The Makarov heard in just the slightest whisper Rouki saying the words 'More experience.'

~ ~ ~ ~Present Time~ ~ ~ ~

"It went on like that for a while." Makarov said to his audience, "Rouki would go out to do a job and come back only to eat, sleep, and go back to do another job."

"Each job was the same," Macao started, "It was either something that involved protecting, or escorting something, or it involved having to hunt down something. All the same he was doing all these jobs because they had one thing in common."

"He was fighting...always fighting." Makarov continued. "Not even once did he take up a job that involved anything else. It soon became clear to me what he was doing."

"He was training." Erza said. She knew because she herself was guilty of doing such at times.

"Yes, training himself through fighting instead of practice. Rouki decided that putting himself in such predicaments would make himself stronger, and they did."

"Every time he left he came back with less and less injuries, and he always took a job that usually the adults of the guild would take. The guy could just sneak in and grab what he wanted and left. For about a month he did all of that." Wakaba said taking another drag of his cigarette.

"We also noticed that the kid had some strange habits." Macao said.

"Like what?" Lucy said, already caught up in the suspense of the story.

"Every time something minor happened to him that he didn't like he looked like he wanted to murder someone. If he stubbed his foot on a chair, it was like he wanted to shred it to pieces. If he was doing something like a puzzle and was having a hard time he looked like he was restraining himself from tearing it up or something like that. He would just be angry at the slightest notice and the smallest thing."

"Then something happened that shocked us all." Makarov breathed deep trying to relax himself. "He had snuck into the guild at night and taken one of the commissions from the second floor board."

~ ~ ~ ~Back then~ ~ ~ ~

"How could you do this Rouki?! Not only have you broken our rules but you have endangered yourself and look what has happened to you!" Makarov shouted in frustration at Rouki who had his right arm bandaged greatly as well as his legs and his forehead. His left arm was in a sling. When Rouki had come back to the guild he was wobbling and merely asked for water with a slight smile on his face.

"The mountain bear-men are ruthless and savage, the fact that you survived is a miracle! I told you that the second floor was for more experienced members! To think that you had the gall to do something like this is sheer stupidity!"

"It worked." Was what Rouki said to Makarov's yelling.

"What?"

"The maneuver I learned. It worked. I was able to defend my left side while able to attack the left immediately after. I just need to go back there and do it again."

"YOU WILL NOT! I will not have you be endangered just for your own fighting prowess!" Makarov took in a deep breath and looked down at Rouki, "If you want to get better at fighting then take the time to practice. Don't recklessly throw yourself into a fray."

"But master, doing so will make me stronger much faster."

"But it will get you killed Rouki. There is much more to life than battle but you won't know what those things are if you get yourself killed!"

Rouki looked to Makarov with sheer determination shining in his eyes. "No."

"No what?" Makarov asked wondering if this child was intent on defying his orders as guild master.

"I will not die. Not for a very long time. I won't allow myself to do so. I need to get stronger. Much, much stronger. But if you insist on keeping me from doing so, then you are of no use to me."

"What?" Makarov's eyes widened at Rouki's last words.

"I joined this guild because It's known as the strongest in Fiore. I also heard it had strong members. I thought that you had such strength because of the commissions that you took. But I have learned that you are only slightly stronger than the last guild I was part of they were holding me back as well."

Many people gasped at this. Rouki's words seemed to be without any compassion or regard to the people in the guild.

"Come on kid, you don't really mean that do you?" Macao said as he reached to Rouki's shoulder. But suddenly Rouki spun around and pushed away Macao's left hand with his own left hand, his arm no longer in the sling. While he pushed Macao's arm away he kicked at his leg behind the knee and forced Macao to fall to a knee. Then Macao felt something cold and hard against his throat. It was the blade that Rouki always had on him, now seemingly slightly longer and less broken looking.

"Macao!" The other guild members called, worried for their friend's safety.

"Let him go!" Natsu screamed as he ran to try and help his Macao. Rouki however flicked his arm out at Natsu and his blade was sent flying at him. The butt of the handle hit Natsu square in the forehead, making him stumble back with his eyes closed. When he opened them again Rouki was right in front of him and was sending a fist at Natsu's face. It connected to Natsu's right eye and made him fall. When Natsu looked back to try to see Rouki he wasn't there. Instead he was directly at the entrance of the guild.

"I could have killed one of your more experienced members Makarov. As well as one of your younger ones. But I won't for now. I know that your guild members can be stronger, and I know I can be stronger! So I'll use you. I will leave and become stronger. Stronger than any of you!"

"Rouki, think about what you are doing!" Makarov pleaded as he looked to Rouki while Macao was being helped up.

"I am. I have always been thinking. I left my home, I created my own form of magic to practice, I've been going through guilds learning what they know to help me. And I've learned that not one of you have anything to teach me other than weakness. I am severing my ties to you here and now Makarov."

Rouki lifted his left arm to show the fairy tail symbol and drew his blade. In one swift motion he slashed a line through the symbol making his blood run out from his flesh.

"I promise you, on this scarred symbol, I will become stronger. I will continue growing stronger and shall continue with my plans to reach my goal. When I feel that the time is right, and I have grown to a point when I feel my power is at it's greatest, I will return to this place. Then I will kill all of you to affirm that power. First the strongest members, then the rest. It will be like you said Makarov, one step at a time."

Makarov looked at Rouki with his eyes showing an unfathomable amount of shock. This boy had been merely staying with the guild to further his own power. He hadn't wanted to make friends, he just wanted to be a better combatant! The tone in his voice alone was enough to convince Makarov of this. He spoke it with no confidence or arrogance. No rage or anything signifying it was caused by a grudge. It was spoken as a fact. Rouki, the twelve year old boy, was assuring everyone that he was going to kill them as if it was a part of nature or that it was planned to happen by the gods themselves.

Everyone in the room was silent. Everyone looked at Rouki, save Lisanna who was being held by her brother Elfman in a protective embrace and Mirajane was standing in front of them ready to protect them.

"Mirajane," Rouki spoke her name and looked her in the eyes. "for being the strongest person at my age in this guild, I will kill you first. When I return our powers should at least be matched."

Mirajane had heard death threats before, from bandits, fools with swords, assassins and the like. All of whom she had fought on a job from the board. But not once had those words been said in such a way. There was no arrogance, no confidence, so absurd snobbish belief in oneself just because they saw her as a weak child. Rouki said it in a way that sounded like he was making a solid promise to her. It quite honestly scared her. It scared her very much.

"Goodbye to all of you, and prepare yourselves. Because one day I will be calling your names."

With that Rouki turned and started walking. Then he disappeared all together. The only thing that could be heard was the shocked breathing of the members of Fairy Tail.

~ ~ ~ ~Back to Present Time~ ~ ~ ~

Those who were listening were stunned. They had just learned that a boy of twelve years old had joined Fairy Tail, only to make a vow to kill everyone within it.

"It was a few weeks after that when Erza came to the guild. We made it kind of an unofficial rule not to speak of him. If only just to ease the memory of him out of our minds so nobody lived in paranoia or fear of him." Makarov finished.

"That is why he has returned. Rouki wishes to test his strength against us. Should he prove strong enough, he will kill us." Macao said grimly.

"If he's back then...Mirajane..." Lucy turned to see the said girl had her hands in a death grip. Elfman had his hand on her shoulder with a determined look on his face.

"He won't do anything to my sister! Not while I'm around." Elfman said.

"Me neither! He wants a piece of us, he'll have to struggle for it!" said Natsu.

"We're all going to be right here, and he's just one guy. He thinks he can win? He's wrong, big time!" Gray shouted along.

"No one is hurting Mirajane!" Levi shouted as well.

Soon every member of Fairy Tail was shouting their voice to fight Rouki.

"When he comes master, we will be waiting." Erza said to Makarov before going to the crowd to talk to Mirajane, most likely to comfort her.

"Maybe Rouki won't get his way after all huh master?" Macao said.

"Maybe..." Makarov said.

"It gives you that much trouble doesn't it?"

"It's not Rouki's words, Macao, that troubles me. It's his motivation."

"Hm?"

"What was it, that drove a boy that young, to have developed such a desperate and dire need to rise above all others in terms of strength and power? What could have put such malice into his heart? It must have been something... horrible."

Swip!

Rouki slashed the air with his sword to make the blood fly off of the blade. Around him were the remains of his adversaries. Perfectly cut pieces of the once huge monster beetles. Their hard outer shells sliced open and their insectoid innards were now laying on the outside of their bodies. With a harmonic ringing sound, Rouki whirled his sword into it's sheath. He breathed in deeply and looked to the sky.

"I...am ready."

And he disappeared.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ So the run down is as follows as people have asked me this.

Rouki joins Fairy Tail to become stronger because they have the claim of being the strongest in Fiore. He figures he would grow stronger with them but due to their rules he sees them as holding him back. This does not make Rouki stronger any faster so he leaves to get stronger. Knowing that they will only get stronger in time he figures if he defeats 'the strongest in Fiore' he will have risen to the height of power he is trying to reach. He is targeting Mirajane first because out of all the children she was the strongest and Rouki sees her only getting stronger due to what Makarov said about her and deduces that in time she would grow to be the strongest in the guild. Rouki also has no knowledge of Gildarts.

By all means please review and tell me what you think!
