It was now early dawn the sun was just rising and Hagoromo just got up to teach Natsu about the power of ninjutsu and to train him on the same day

"Wake up Kiddo it's time for your lesson." Said the elder but no response until a few moments Natsu finally woke up

"What it's still too early why now?' Said Natsu before Yawning

"Natsu you will need to train on always being ready for any hour of the day, even if it means getting 1 hour of sleep or less." The elder said to Natsu

"Ok Ok I guess i'm ready for my first lesson on the thing you're going to teach me right?"

"That's correct Natsu I will be teaching you on Ninjustu and other powers. The first thing to know is Ninjutsu doesn't come from Magic it comes from a power called Chakra, it is slightly different from magic but it has similarities. Chakra came from a big tree known as "The Divine Tree" and it had a fruit that could give you infinite amount of power and chakra but one day my mother ate it to stop the wars that were going on. Even though she did stop the war people started getting frightened by her and called her the Rabid Goddess, because she was not as gentle as she was be before she ate the fruit. She was getting blinded by all the power she got from the fruit. Years later she had two sons which were me and my Brother Hamura Otsutsuki. My brother and I were seeing how Mother was getting out of control so we took Matters into our own hands and Sealed her up so she could possess no more harm."

After hearing this Natsu was completely shocked to hear that this elder man was the son of a Rabid Goddess and had a brother of his own.

"Wait Great Grandpa what happened to you're brother?' said Natsu looking at the elder. "He went to the moon to watch over the earthland and to see if there was any danger on the moon. But he passed away a few years ago because he was t getting old like me." said Hagoromo looking at Natu answering his questions

"So how long can you live up to then Great Grandpa if you know all of this then how old are you?" asked Natsu "I am many millenniums old Kiddo I am only here because I still have some life in me but in a few years I will have to leave you Natsu. Do You understand that Natsu. "What but why Great Grandpa please don't leave me." said Natsu hoping that is wasn't true. "I'm sorry Natsu that I will have to leave you but before my time will be up you will be the strongest out there and then you can make all the friends that you want." Said the Elder trying to cheer Natsu up

"Oh OK but at least promise me that you will be safe and watch over me Great Grandpa." said the child hoping that at least his request would be promised. Hagoromo looked shock that the child actually cared about him, not that much people have cared about him in a while since he was older than magic itself. "Don't worry Natsu I will simple go to the after life with my family and I will be happy, I promise I will watch over you after I leave. Ok Natsu?"

"OK Great Grandpa as long as I know you will be safe then I understand and I will be ready for that when the time comes. But quick question that's been bothering me since yesterday Grandpa, why did you decide to call me that, it's not that I don't like but why didn't you give me your last name Grandpa?' asked Natsu looking at Hagoromo "Well long ago when chakra was still around Natsu there was a Young Lad who had the exact goal, personality and same big goofy smile on his face and you reminded me so much of him. His name was Naruto Uzumaki even though he became one of the strongest out there he never forgot about his friends and he never betrayed them either, also I named you Uzumaki because Uzumaki was a Clan known for it's red hair and your hair is almost like a Uzumaki except it's pink."

"HEY IT'S NOT PINK IT'S SALMON!" yelled Natsu because he thought pink was a girly color and his hair was a different color

"Hush Child any way we are going to have to train you to hold your temper and anger for your future battles because it can get you to lose or to get killed. Ok?" Said the Elder "Ok, but can we go back to the lesson you were telling me about? It seems that we got a bit distracted." Hagoromo also realized this and said "Yes you're right it seems we got side-tracked, anyway after my brother and I sealed Mother we went out to do what we wanted. I had two sons whose name was Asura and Indra, Indra was older than Asura, he was talented, gifted with the power like I possess and was extremely intelligent so that meant he could do anything on his own. Asura however was the complete opposite he had no talent whatsoever he was clumsy unintelligent and needed help to do everything, but he overcame these weaknesses by having comrades and allies to help him to become strong and to have bonds with everyone of them. The two brothers had the same goal which was to acquire peace and harmony, however they had different ideas on how to achieve it. Indra wanted to do this through violence and force, but Asura wanted to achieve it through words and peace with non-violence. I decided that I wanted to entrust everything I had to Asura since I thought his way of achieving was much better than Indra's. However Indra was enraged about this and decided to fight Asura about that, the battle lasted for a while but event though they both died, the battle between two brothers never stopped. Their Chakra was passed into their reincarnations until one finally put a stop to this battle. This was Naruto, he was the Second Reincarnate of Asura decided that he wanted to stop this battle and work with Indra's Reincarnate. Naruto has succeeded and after his and Indra's Reincarnate's time was up, my sons chakra's never were put into anybody else. But it seems that Asura's chakra is inside of you Natsu and that means that I will be able to teach you Ninjutsu since you already have chakra inside you. Also I can give you Indra's chakra so you can awaken the sharingan and the rinnegan, you will possess these two powers at the same time. There was only one person who has done that and that man's name was Sasuke Uchiha, he was Naruto's best friend and when they were adults they were unstoppable. Anyway with my help I helped sasuke awakened the rinnegan, but it was an alternative version of one it was a variant of a more powerful eye which was the rinne sharingan. Also his rinnegan was stronger than a regular rinnegan and looked a little different from one too. A regular rinnegan was just violet purple with no tomoes and vertical lines that's it, but Sasuke's was a little different his had 6 tomeo in his rinnegan eye he can use for space-time jutsu (teleporting), he can use it to travel to different dimensions, repel any and all physical attacks, and also he can see what is impossible to see."

"Are you still with me Natsu?' asked the Elder "Yes I'm still with you grandpa this is all quite interesting and entertaining at the same time. So you're telling me I am going to awaken the sharingan and the rinnegan in the future?" Natsu asking to see if it was true about him getting these powers "Yes Natsu with my help and knowledge you will definitely awaken both and acquire both of their powers but I will make sure to give you the Eternal Mangekyo sharingan because if I just give you a regular Mangekyo sharingan and you overuse it, it can permanently blind you. Do you Understand so far?" asked the elder "Yes I completely understand this Grandpa." said the child while looking the the Elder "But I won't always have to rely on these powers will I, I don't think I will survive if I depend too much on these powers Grandpa." Said Natsu

"Yes you are correct Natsu it would be bad if you rely on these powers too much, anyway your training will start after we eat some breakfast. You will have to catch and hunt you're own food do you understand that Natsu?"

"Yes I completely understand all of this let's go I'm getting hungry anyways." The child said with energy now being wide awake and feeling determined to train

2 Hours Later

"Okay Natsu your first lesson is to learn to to control your chakra, I can tell that you are not able to control your chakra right now. Also to charge your chakra simple just concentrate your mind to do so since this is your first time, in the near future you will be able to do this without a sweat and you wil be able to do it in your sleep. Ok Natsu give it a try, charge your chakra."

"Okay I'll do the best that I can" said natsu before taking his two hands into a chakra charging position and started to try and release his chakra 'Hmm it seems that this will only take shorter than I expected this to be' Hagoromo summed up that this will only take him a few hours to teach Natsu how to control his Chakra

A Few Hours Later

"Ok Natsu now that you have mastered controlling your chakra we will work on your physical strength and stamina I want you to do 500 Push ups only using one hand, then do 500 sit ups, then I want you to run up this mountain and back down 50 times and this will be your exercise everyday while I will still be with you. Do you Understand? I expect you to do this before our training for the day is over." The Elder said with Much Authority in his voice. 'I know I might be hard on the kid but if he wants to get strong then he will have to endure all of this if he wants to get strong.' Hagoromo thought

"What you expect ME to do all of this before the end of the day it's impossible I'm still a kid!" Yelled Natsu and he was surprised that his training is already tough, he thought that the old man was gonna go easy on him since his first training on controlling his chakra was more than a little difficult. "NO Natsu you are going to do this or else you WILL get the consequences!" Yelled the Elder in a commanding and scary voice that sent chills down Natsu's spine

"OK OK I WILL DO IT DON'T PUNISH ME!" Said Natsu in a panicky voice since he didn't want to see or face the consequences since he was frightened about finding out what they were.

Time Skip

It has been 5 Years and Natsu was now 10 years old, he was only 5 when Natsu was found. Ever since Natsu's training has started and he can do the exercise he was told to do everyday with ease, without breaking a sweat doing it all in 1 hour, also since he got used to it all of his exercises tripled but Natsu still did them with ease, but Hagoromo only added more exercise such as Handstands, Squats, Doing kicks for a while, and Natsu was forced to wear Clothing that weight 2 tons. However his stamina and physical strength have increased exponentially and he is able to stay awake for 3 weeks straight without any sleep, or food. That was torture in Natsu's opinion since he couldn't eat anything, it was his most favorite thing in the world besides training.

Also Hagoromo taught Natsu how to read, right, talk properly, how to be nice and respectful, how to control his temper. He still told Natsu stories about the world of Chakra and the People who had it, and also told Natsu "The Talk" and told the child about the birds and the bees and Natsu was scarred for a while and was no longer a child in his mind anymore. Hagoromo also taught Natsu about the Nature Types: Fire, Earth, Water, Lightning and Wind. Also he taught Natsu about Yin Yang Type and Natsu seemed to have all of these Nature Types. Also Natsu has increased all of his five senses ten fold, his nose and ears were sharper than a dragon slayers, even though Hagoromo taught Natsu ninjutsu, he still taught the young lad about the type of mages he will probably meet such as Requip mages, take over mages, celestial mages etc. The elder also taught him about lost and ancient, that's how Hagoromo taught Natsu about dragons and dragons slayers, the elder told Natsu that dragons will disappear on the date 7/7/X777 and told Natsu about where they will go and why they would leave their place.

Natsu even met a few dragons, the first one he met was Igneel King of the Fire Dragons, the second was Atlas Flame, others were Metalicana the Iron Dragon, Grandeeney The Sky Dragon, Weisslogia the White Dragon, and Skiadram The Shadow Dragon. They were all really nice in Natsu's opinion and he gained the power to be immune to all of their magic, Natsu also learned some of each of their magic so he could use it to his own advantage. But Natsu was told not to tell their Dragon Slayers where they would be, but he could tell them how they were and could say that he can communicate with them.

Also Natsu activated the sharingan while training with the Sage when Natsu was only with the sage for 3 years. Natsu awakened the mangekyo sharingan and it was exactly like the Uchiha ancestor Sasuke Uchiha. Natsu's susanno was exactly like Sasuke's in every way and ther was no difference. Natsu also had a transformation called Kuruma Mode. It took the transformation of the Nine-Tailed Fox except the Nine Tails was glowing yellow around his body, it also transformed all of Natsu's Body gold and it gave him a chakra cloak and in that transformation Natsu could sense the hatred and negative emotions in that transformations, but Natsu trained to do that in his normal form He also evolved it into Six Path Sage Mode. Unlike Kuruma Mode when Natsu turned into the six path sage mode his skin would not glow golden only his clothes would Natsu would only use transformations when he would want to go all out. Natsu could destroy four mountains by just screaming at them or touching his finger with them, but the kid could control his power so that would only happen when he wanted to.

Natsu also learned sage mode and it looked like Naruto's sage mode and Naruto's Father Minato Namikaze's as well. Unlike other people Natsu has learned to transform into it while moving with the help of the Sage Natsu figured out a way to do it but it was not easy but challenging. The child also learned the "Shadow Clone Jutsu" with this Natsu could duplicate himself and he could make 1000 clones by himself without anybodies help or Magic. Also he learned that Dragon Slayers have motion sickness so natsu trained so he would get over it and he did though it felt like his stomach wanted to jump out of him.

"Okay Natsu we are starting a new type of training today, you will try to walk or run up all the way to the top of this tree without falling. Do you understand Natsu?" Hagoromo asked Natsu while looking at a tree that was half as tall as a sky scraper. "You will need to channel you're chakra to your feet to walk up to this tree. Am I clear Kiddo" The Elder asked taking a look at Natsu to see if he understood his instructions

"Yes I completely understand Grandpa I will do this" said Natsu before holding his right hand up close to his face pointing his first two fingers up and his his other fingers closed while charging his chakra to his feet. "Ok HERE I GO!" Yelled Natsu at the top of his longs before running up to the tree

It took Natsu only a few hours to fully run and walk up the tree but it seemed Natsu was still ready to go. "Okay you're next training will be to walk on this water, here I will show." Stated the Elder before Walking on the water. "Okay Kiddo now you give it a try."

"Ok here I go-AAAAAHHHHHH!" Natsu yelled as he fell into the water, "HAHAHAHAHA, don't worry kiddo just keep trying until you get it right. Ok Kiddo?" The elder said while smiling and looking at Natsu's process. "WOAH! I think I'm starting to get this now look." Natsu said while was walking on water but the watter was up to his knees. "Okay I'm going to try to stand on all the water. HAAA!" The child yelled as he was fully standed on top of the water and running around it. "Yay I DID IT I DID IT I DID IT!" Natsu stopped when he heard a large roar comming from very far away but Natsu could travel faster than the speed of sound so Natsu could get to it easily.

"Old Man did you hear that it sounded like a Roar it sounds like one of those demons from Zeref's book that you told me about." said Natsu while trying to figure out if it was or not.

"Well it seems that you paid attention during that lesson I see and yes it is a demon from the Black Wizard's Book." said the Elder "Hey it didn't look like I was paying attention because you didn't let me eat food for days, but I still paid attention. Anways are we going to go check it out Old Man" Natsu asked the Sage waiting for a responce which took him a few moments before he got an answer. "No kiddo you will do this on your own to see if you are strong enough to take on a demon yet. Understood Natsu?"

This shocked Natsu for a second before understanding to see if his training with the Sage was enough to help him protect innocent civilians. "I understand this Old Man, I will defeat this demon without breaking a sweat!" Natsu said this with determination before picking up his katanna that was owned by Sasuke Uchiha, Natsu grabbed a black cloak with a hood and running in the direction before running in the direction of the scream, Natsu used his chakra dash but unlike Ninja's who owned chakra Natsu still used his arms but his back was how Ninjas in the past run so Natsu looked still slightly normal while running.

When Natsu arrived he ran up a tall building and saw people running out of the city but there was a woman who looked about in her mid 20's and short wave purple hair that went only above her shoulders with two children who looked to be the same age of Natsu. One boy had silver spiky hair, and the other had raven spiky hair.

Natsu then turned his head to look at the cause of the scream and it was Deliora one of the demons from the book of Zeref. It was about to shoot a blast from his mouth and aiming at the woment with the children. Natsu put on his hood from his cloak on and ran in front of the womant and knocked away the blast to the direction of the sky with only the back of his hand.

"M'am Take the children and get away from this area, I'll take it from here. Okay" Said Natsu with his hood still on. "No please take my pupils and take them away from here I am going to seal Deliora, also my name is Ur." Said the woman looking at the hooded person. "NO I WILL TAKE DELIORA DOWN! Just stay back okay?" said Natsu before holding up his hand and making a blue sphere spinning in all directions inside of the sphere, the sphere got bigger and it was 10 meters long and 10 meters wide. Natsu then jumped to a building then went straight to Deliora "Sage Art"

"GIANT RASENGAN!" Natsu hit Deliora's arm and it got destroyed completely, Natsu then created a clone and had another Giant Rasengan aiming at Deliora's other Arm. "I'm going to finish this now SAGE ART MASSIVE RASENGAN MEGA BARRAGE" Natsu yelled before 100 clones came from the sky all with a giant rasengan and hitting Deliora destroying it completely and turning it into ash.

Ur just watched in awe on how a person could defeat it with such a calm and confident personality, the hooded figure then went over to the trio and taking off his hood. It was a boy with wild pink hair and tanned skin with a calm face. "Are You three Okay?" asked Natsu looking at the three. "Y-Yes we are all okay thank you for saving me and my students . Also how were you able to do that if you are only a child not much older than my students" said Ur while looking at her students to see if they were ok and they were.

"I'm sorry I really don't have time to explain I have a place I need to get to. Thank you and Goodbye" Natsu said before what looked like he teleported but he atually just ran in the direction he came from. "WAIT I forgot to ask you for your name." Ur said while trying to see if he was still nearbye but it was no avail since he was gone. But Ur never forgot his face and she hopes in the future she will see him again ask him for his name

"Well that was easier than I expected I only used 2% of my strength" Natsu said to himself while he was going back to Hagoromo
