Here is the re-written version of chapter 2 enjoy.

Chapter 2: Dragon slayer magic and the siscon family

Itachi sat upon Tannin's head as they flew over the mountain valley. "What are we doing here?" Itachi questioned the dragon.

"Well since I have decided to adopt you as my own son. I figured you need to learn a special kind of magic, and this place is perfect for training." Tannin replied to his new adopted son.

"Why is this the perfect place?" Itachi questioned as Tannin flew down to the top of a mountain

"Because with the kind of destructive power I will teach you, we will need a place to destroy things that we don't have to replace." Tannin replied and Itachi sweat dropped.

'Couldn't there still be people or other dragons on one of the mountains?' Itachi thought and activated his sharingan looking around for any sign of life around them. Itachi then looked up to his new tall dragon father. "What are you going to teach me anyway?"

"Dragon slayer magic." Tannin replied.

"Dragon slayer magic?" The young Uchiha questioned.

"Yes, dragon slayer magic, it's the kind of magic that will give you the ability to slay a dragon." Tannin said while crossing his arms and looking down on his adopted son while they were standing on a mountain top.

"There isn't any final test where you and I have to fight to the death is it?" Itachi questioned with a straight face.

Tannin laughed which was so loud that Itachi had to cover his ears to not lose his hearing. "No there is no such test, but when you're done mastering it we can have a friendly match if you'd like?"

"No thanks I would rather avoid fighting anyone." Itachi said still with the emotionless Uchiha face.

"But I'm teaching you magic designed for combat so you can use it in a fight." Tannin said thinking Itachi was afraid of fighting.

"I don't really enjoy fighting even if it's a little sparing match." Itachi said thinking Tannin was trying to make him a soldier to fight in a dragon war or something.

"You don't enjoy fighting, what are you a pacifist?" Tannin jokingly said thinking Itachi didn't understood the word.

"Yes I 'am, I only fight when someone I care about is in danger or needs my help." Itachi said while thinking of his younger brother Sasuke and former lover Izumi.

"Then why not learn this magic for when such a time comes." Tannin asked with a small smile. (not that anyone could tell by looking)

"Wait so you're not going to make me into a soldier?" Itachi asked.

"A soldier why would you think that?" Tannin asked

"For some dragon war or at least to fight in some battle, why else would you teach me something called dragon slayer magic." Itachi replied

"Because that's the only magic I can teach a human like you." Tannin said but shocked that such a little boy would be able to think about such things. "And don't worry about some dragon war because there is no such thing, when a dragon fights another dragon its considered sacred and no one else is allow to interfere."

Itachi was relieved that the dragons had such a simple system of solving their own conflicts instead of dragging several people into it.

"But before I teach you anything, you said you know ninjustsu do you mind showing me some of your abilities?" Tannin was curious about what this kid could do.

Itachi thought about it and he found this to be the perfect opportunity to see if he really could use all five elements. "Alright then."

Itachi did a few hand signs he was going to try what element he knew he could use first

Fire style: Fireball jutsu

Itachi said and spitted out a large ball of fire.

"Impressive." Tannin praised. "Anything else?"

Itachi did another set of hand signs.

Water style: Water shark bomb

Itachi said and manifested a shark of water out of a small puddle.

"First fire and now water huh, can you do more?" Tannin asked surprised so far of what a four-year-old human child could do.

'Okay I had this element back in the element of nations but it wasn't very strong, oh well here goes nothing.' Itachi thought and performed the hand signs.

Wind style: Vacuum bullets

Itachi said and spitted out six wind blows that where shaped like bullets, they were able to penetrate a tree creating three holes that that put together were in the shape of a triangle.

"You really are interesting Itachi show me more." Tannin who felt a small sense of pride at what his adopted son could do.

'Okay time to test out an element I couldn't use back in the element of nations. If I recall the hand signs go like this.' Itachi thought and performed the hand signs.

Lightning style: Lightning beast runner

Itachi said and manifested a beast out of lightning that crashed into what remained of the tree and destroyed it.

"Alright then I don't need to see anymore now let's begin your training." Tannin said

"Wait Tannin-san I need to check something." Itachi stated knowing it was one more element to test.

"Fine, fine but you don't have to call me Tannin-san you can call father you know. After all I have adopted you as my son"

Itachi looked surprised, he knows that Tannin has adopted him, but that Tannin wants him to call him father. Itachi had a small happy smile on his face. "Alright then tou-san." Itachi performed the hand signs for a simple earth jutsu.

Earth style: Mud wall

Itachi said while slamming his hands on the ground and up came a wall made out of earth.

"Fire, water, wind, lightning and earth, you can use all the five elements." Tannin said while looking at Itachi. "That's my boy."

Itachi felt happy at first but that happiness slowly turned into sorrow, being reminded of those words that his father used to say when he had made an accomplishment.

"Alright then ready to start your first lesson?" Tannin asked knocking Itachi out of his train of thought.

"Yes tou-san I'm ready." Itachi declared.

"Alright then watch closely, first you gather a lot of magic power to your belly and then you release it out."

Blaze Meteor Dragon ROAR!

Tannin yelled while spewing out a huge amount of fire that ended up destroying another mountain in front of them.

"Well what do you think Itachi?!" Tannin proud fully shouted and laughed.

While Tannin was laughing Itachi asked him one question. "Tou-san, what if there where someone on the mountain you just blew up." Itachi said with a straight face. Which made Tannin stop laughing and pale.

"Uhhhh" Tannin didn't know how to respond as a crow flew past him.

"Ahou! Ahou! Ahou!" The crow shrieked as it flew past Tannin.

"Relax tou-san no one was there I was only joking." Itachi said with a smile

"You little brat don't scare me like that!" Tannin yelled which resulted in Itachi covering his ears.

"You're too loud tou-san."

"Well get used to it!" Tannin yelled. "Now it's your turn."

Itachi focused and found a power inside him that felt different then chakra and came to the conclusion that it was magic power, he couldn't believe how much of it he had it was almost as large as his chakra. He focused that power in his belly and released it.

Blaze meteor dragon ROAR!

Itachi spewed out a large amount of fire but not as large as Tannin's. Itachi looked a little disappointed, while Tannin was gaping that Itachi had actually done it.

"You did it you actually did it." Tannin said in a shocked voice.

"It wasn't as large as yours tou-san, I'll try again." Itachi said determent too get it to be just as large or larger then Tannin's.

"EHHHHHHHHHHHHhhhhh!?" Tannin yelled.

Later Tannin pov

The training for the day was over and Itachi was so tired that he fell asleep in Tannin's hand as they flew back home.

Tannin looked at the little boy and couldn't help but smiling. "You've done well kid now rest." Tannin said as he flew back home.

Later Itachi pov

It's been two years since Tannin adopted Itachi. And in just two years Itachi has mastered the art dragon slayer magic. His power had increased so much that he already felt as strong as he was when he first started in the ANBU back in Konoha.

Itachi was sitting on a rook eating his bentobox, when Tannin arrived.

"Itachi swallow this will you." Tannin said holding a small glowing ball at the same size as your average pill.

"What is it?" Itachi said holding the glowing pill ball.

"It's medicine just take it." Tannin had a serious expression on his face.

"Tou-san I'm not taking it until you tell me what it's for." Itachi said with a determent face.

"Huh, fine you win it's to prevent you from becoming a dragon." Tannin said with a sigh.

"What do you mean prevent me from becoming a dragon?" Itachi questioned narrowing his eyes.

"Look I'm pretty sure you're aware that you're not the only dragon slayer." Tannin said and Itachi nodded. "There has only and is only been one other dragon slayer." Itachi looked at Tannin curiously wondering who the other dragon slayer is. "His name is Yagura, his a water dragon slayer he was trained by my good friend Aquados the water dragon."

"What happened between Yagura and this dragon Aquados." Itachi questioned.

"Unlike you Yagura only desired power, and when he was fully trained he killed Aquados and bathed in his blood and became a dragon." Tannin replied and Itachi wasn't surprised judging by the way Tannin started the story it could only end badly. "It's a fate that happens to all dragon slayers that's why I'm asking you to swallow this lacrima so that you don't turn into one."

Itachi looked at the lacrima then back at Tannin. "And I didn't get this information 2 years ago because…?" Itachi questioned with his eyes narrowed.

"Hey it's not that easy to make one it takes time!" Tannin shouted dodging answering the question.

Itachi just shrugged his shoulders and swallowed it with some water. "There does this mean I won't become a dragon?"

"Yes I'm a hundred percent sure so don't worry." Tannin said when he remembered something. "Itachi, pack your things were leaving." Itachi didn't argue he went and grabbed his things and put them in a bag, then he jumped up to the top of Tannin's head and they flew up.

As they were flying Itachi noticed them leaving the dragon valley. "Where are we going?"

"I have arranged with an old friend of mine that you will be able to study with his little sister as well as living there." Tannin answered.

"But why?" Itachi questioned

"Look Itachi there are a few things that I can't teach you such as school stuff, and I'm busy with a lot of things now henceforward the living arrangements." Itachi knew Tannin's reason and didn't decide to ask anything more of the subject. "Besides you could use a friend, it's not healthy for a kid your age not to have friends." Itachi remained silent at that comment. "Uh and one more thing if she asks you if you want to be a part of her peerage please consider it, if you have a reincarnated devil body your strength, speed and stamina will increase." Tannin suggested.

"I'll think about it." Itachi replied. Having already learnt that this was the underworld and not the human world, and about how the devil's lost so many of their own during the war. They were low in numbers and created a system called evil pieces where they reincarnate humans into devils.

"Ah there it is the Gremory castle." Tannin said while going down to land on the ground. "Now I will come and visit you every now and then take care." Tannin flew off.

Itachi went towards the door to see a few guards guarding it." State your business boy?"

"I'm Tannin's son I'm here to study with Rias-sama." Itachi answered.

"Oh, yes Rias-ojusama is exited to meet you please go right in." the guard said opening the door.

Itachi walked around the castle and had but one thought it's ridiculously huge. He walked around when he heard the voice of a girl. "Hey are you Tannin's son?" he turned around to see a girl that was the same age as him she had long crimson red hair and bright blue eyes.

"Yes I'm Itachi Uchiha I assume that your Rias Gremory, it's a pleasure to meet you." Itachi introduced himself and bowed.

She looked at Itachi with excitement the kind of excitement Itachi only had seen in Sasuke and Izumi.

"Huh so this is Tannin's boy huh." A man with long crimson hair tied as a loose ponytail with a black hairband, he had bright blue eyes just like Rias, he also had a short red beard. "My name is Zeoticus Gremory, but everyone just calls me Lord Gremory."

A woman that looked like an older version of Rias only that her hair was short and brown and her eyes where violet. She also looked like she was in her teens, which got Itachi thinking. 'Doesn't she and Lord Gremory have a son that is already an adult? How is she so young?!' Itachi thought.

"Greetings I 'am Rias mother my name is Venelana Gremory." Rias's mother introduced herself.

Itachi bowed "My name is Uchiha Itachi, Uchiha is my family name." Apparently, devils tend to use their names first before their family name.

"Oh, since you say your last name first must mean that you're from Japan." Lord Gremory said as he looked down on Itachi. "But honestly aren't you here a little early?"

"Huh?"

"Well the deal my son made with Tannin said that you would be coming around fifteen minutes before class starts and it's not starting until 2 more hours." Lord Gremory explained meaning that Tannin brought him here 1 hour and 45 minutes too early. 'He probably couldn't wait to get me out huh, lazy dragon.' Itachi thought with an annoyed expression.

Itachi felt something grabbed his arm he looked and saw that it was Rias. "Let's go play."

"Play?" Itachi questioned.

"Yes play come on." Rias dragged him up the stairway as Itachi looked surprised at how much energy this girl had. It was almost like back in the day when Sasuke would ask him to train him.

While Rias talked about being exited to have her first male friend, Itachi was still wondering how Venelana stayed so young despite her actually being old from what he had heard. 'Did she use something similar as the fifth hokage Tsunade, or did she use a spell?' Itachi was broken out of his train of thought when he saw Rias looking angry at him with a pouty face.

"Were you listening to me at all?" She asked with the pouty look.

"Um no my apologize Rias-sama I was thinking about something." Itachi apologized. "So what were you saying?"

She looked away and blushed. "I wanted to ask if you would be, my friend." She started tearing up but then. Making Itachi smile a little.

POKE

Itachi poked her forehead and smiled. "Of course Rias-sama."

Rias then gained a wide smile that quickly vanished and was replaced by a pout. "Mou don't call me Rias-sama, just call me Rias after all real friends don't use honorifics."

Itachi blinked his eyes a little then he chuckled a little. "Alright then, Rias." Itachi replied with a smile.

She then hugged Itachi then dragged him into some sort of garden where they could play.

In the distance

A dark figure stood on top of a tree, speaking into a magic circle. "Yes boss I will release the test now."

Back in the garden

A magic barrier was suddenly formed around the garden. Although Rias didn't notice it, but Itachi did and Itachi sensed some evil presence, he felt a killing intent in the air. "Rias watch out!" Itachi yelled covering Rias before being slammed into a wall.

It was a large beast on the bottom it looked like a giant spider but it had claws like a scorpion, and half of what looked like a human body upper body the only thing was that it had six black eyes and on the spider part was a large mouth with sharp teeth.

It charged towards Rias and Itachi. Itachi quickly got up and charged with a blue orb that suddenly burst into flames. 'It took me long enough to master the rasengan, I haven't tested it out against an opponent yet. So here goes nothing!' Itachi thought.

Blaze Meteor Dragon Rasengan

It hit the beast in the stomach sending it flying into pillar. The beast then got up from the rubble while it roared at Itachi with rage. It grabbed the pillar with its claws and just as Itachi thought it was meant for him it threw it towards Rias, for the first time Itachi didn't think his body just moved on its own. He ran up to Rias threw her out of harm's way, but the pillar hit Itachi in the right arm causing his arm to break. "Argh!" Itachi grunted in pain.

The beast went to attack Rias thinking that itachi was out of the picture but then.

Blaze Meteor Dragon Talon

Itachi kicked it in the head with his leg covered in flames.

Itachi was standing in front of Rias facing the monster. His right arm was broken he had some bruises from a few rock pieces from the pillar that had hit him in the head which caused blood to run down over his left eye. "I'm still here monster." Itachi said.

The monster roared and charged at Itachi. Itachi grabbed Rias and leaped back to safety. Itachi placed Rias down and leaped towards the monster bringing out some kunai knifes from his pocket. 'Lucky me I know how to make my own kunai knifes.' Itachi thought and threw the kunais.

The monster dodged them and kept charging towards Itachi. Itachi then pulled his arms back as the sound of some wire was heard. The kunai's were then pulled back and stabbed the beast in the back making it shriek in pain.

Itachi couldn't risk dragging the fight on any longer. "Time to end this." Itachi said.

The monster charged at Itachi. Suddenly they were only a few inches away from each other, their eyes meet. Itachi saw the black eyes of a cold-blooded monster, the monster saw Itachi's eyes transform into red eyes with three black tomoes and a black dot in the center Itachi's eyes then morphed into a black pinwheel that had a red star in the center and the monsters fate was sealed.

Tsukuyomi

Meanwhile

Lord Gremory and several of his guards ran to the garden but then faced a magic circle and out of it came a young man with crimson red hair that reached to down to his upper back, he had blue eyes and was wearing some sort of robe with shoulder pads that had spikes on them, the man was Sirzechs Lucifer. "Where?" was all he asked and his father pointed at the garden.

They saw a stray devil charging at Rias and Itachi, they tried to reach them but a magic barrier was in their way. Just as Sirzechs was about to destroy the barrier, the monster stopped and feel dead on the ground. Sirzechs destroyed the barrier and the remains off the monster. Sirzechs went up to Rias to see if she was hurt but she just ran out of her brother's arms and went to Itachi who had passed out.

She cried. "Itachi wake up please wake up." She begged and cried over his unconscious body.

One of the maids went to check on Itachi.

"How is he?" Lord Gremory asked.

"His right arm is broken and losing much blood he has a few bruises that aren't too serious other than that he's just tired he should wake up in a few hours." The maid responded.

"Take him to his assigned room, and get some medical supplies to treat his injuries." Lord Gremory ordered as the maid lifted Itachi up and walked back inside with Rias quickly following behind.

A few hours later

Itachi woke up in a large bed, he looked around the room to see Rias crying with her face buried in the bed as she was holding Itachi's hand. "Rias are you all right?" She immediately looked up and hugged Itachi crying into his shoulder.

"I thought you might never wake up." She said with tears dripping from her eyes.

"Ah so the young hero's finally awake." Itachi looked at the door at the end of the room to see a male older version of Rias standing there with a white haired maid next to him. "I' am Sirzechs Lucifer one of the four maous and Rias's older brother, I wanted to thank you for saving her."

"I'm Itachi Uchiha, and you don't have to thank me I was only doing what was right." Itachi replied while Rias was hugging him.

Sirzechs's expression changed from a smile into a little jealous expression as he was seeing his precious little sister hugging Itachi while ignoring him. "Ria-tan come and give your onii-chan a hug." Sirzechs said as sparks flew around him, although nothing happened since she still ignored him. "Waaah Ria-tan how can you be so cruel! I just want a hug!" Sirzechs cried with a dark cloud hanging over his head. At that moment, the maid began to pinch Sirzechs cheek.

"You've said you're thanks to the young man it's time to get back to work." She said with an emotionless expression while dragging him out of the room.

"Argh! Graifya it hurts! It hurts!" Sirzechs cried as he was dragged out.

"Rias?" Itachi said with an emotionless expression while looking at where Sirzechs stood.

"Yes Itachi." Rias said still hugging him and she had stopped crying.

"You have a strange family." Itachi bluntly commented.

"I know." Rias responded.

Location: unknown

"Boss, the test of the new dragon slayer was a success he annihilated the stray devil with ease, he might not even have been injured if the Gremory girl wasn't there." A man in a knight armor said bowing before a hooded figure who was sitting on some throne. "But there was one unexpected thing boss."

"Do tell." The hooded figure said with his hand on his cheek.

"The dragon slayer had sharingan, just like you boss." The knight said as the hooded figure opened one of his eyes reviling a glowing red eye with three black tomes and a black dot in the center.

"Really, now that's interesting, I wonder how you will face off against him in the future Yagura." The hooded figure said suggesting to the teen that was hidden behind a pillar. Yagura was in his teens he had long spiky white hair that reached to his shoulders, and green eyes, and he was wearing a green shirt with a symbol of a black western dragon on it and some black pants.

"I just hope when the time comes it won't be boring." Yagura said with an evil grin. "Itachi Uchiha the son of the blaze meteor dragon Tannin, I can hardly wait."

And that's it for now!

Anyway, some people have asked why there is someone that has knowledge of sharingan and possesses it. Well all I can say is that this OC villain of mine here has had the ability to use it since he was a child, as for why he could awaken it well that is explained in chapter 22.

Anyway, I will keep re-writing some chapters this summer. So far, I have planned to re-write from chapter 1-10, I will see if there is any need to re-write further than that.

Anyway, it would be nice if you guys would leave a review.

-Later!
