Third P.O.V.
When Natsu tried to open his eyes, he was blinded by the bright light hanging above him, when his eyed adjusted to it, he noticed 3 things, 1) was that he was wrapped in bandages, 2) There was a sleeping blue haired girl and a red haired old man smiling at him, 3) was that he wasn't on Tenroujima, He shot up remembering Acnologia. Before he doubled over in pain.
'I guess fighting that God slayer, then that cross dresser, that fat weirdo, hades and Acnologia will make it a little hard to move.' Natsu thought to himself as he started getting out of bed.
"Calm down Natsu, you are in no danger here." the old man said, this made Natsu curious. How did he know his name?
"Who are you old man? And How did you know my name?" Natsu asked cautiously while prepare himself to run if need be, because he knew he was in no condition to fight.
"Isn't it polite to introduce yourself first before asking for someone's name. Though considering you were raised by a dragon I guess it can't be helped. My Name is Nagato Uzumaki, and the sleeping girl is Konan Uzumaki, my Great Great Great Great Granddaughter, and I know your name because, you are Konan's Little Brother, and my Great Great Great Great Grandson, Natsu Uzumaki." The now named Nagato said with a grandfatherly smile.
Natsu was stunned by this, he had Living Family, and they were right in front of him, he felt tears start to surface from his eyes as he jumped at the old man, wrapped his arms around him in a tight hug. While shouting oji-san. When Natsu did this he accidentally woke Konan, she looked around, before looking at Natsu hugging their ji-san, she smiled and joined the hug.
After the recently reunited family finished their hug, Nagato decided that he need to ask his grandson some questions.
"Natsu I need to ask you a few things before we continue our little reunion." Nagato said with every bit of seriousness as he could. Natsu seeing his recently revealed jiji being so serious decided it was best to listen.
"What is your first memory Natsu?" Nagato asked.
"Well I woke up in the woods, with my head hurting and my chest hurting. Then Igneel found me after that he raised me." Natsu said while scratching the back of his head trying to concentrate. Konan thought his expression was adorable.
'My baby brother is so cute! And look at those muscles, he looks like he was cut from a block of marble! I wonder what they feel like? No bad Konan he is your brother.' Konan scolded herself to herself as her thoughts got worse and worse. While konan was in her own little world, natsu and Nagato continued their conversation.
"So the first thing you remember is waking up in the woods in pain around your head and chest. Ok, natsu a few more questions and we are done. Can you tell me what color your has always been? What color your eyes have always been and if you remember a young black haired man when you were younger?" Nagato while having a sinking feeling about what happened to his grandson.
"My hair has always been salmon, my eyes have always been this color and no I don't remember any young black haired guy when I was younger. First person I met with black hair is Gray." Natsu told Nagato while trying to figure out why his grandfather wanted to know all of this stuff that to him seemed kinda pointless. However when Natsu answered Nagatos questions, Nagato had a pretty good idea what happened to his grandson.
"Natsu I need you to come over here and let me look at you" Nagato said which severed to knock Konan out of her daydream and wonder what she missed. Natsu seeing no problem with it walked over to his jiji's chair. (Nagato looks like he did from the edo tensei except with white hair, so no big metal walker thing and Konan is wearing the same thing she does in naruto under the cloak.) Nagato removed some of the bandages off his grandsons torso, while examining him with his strange eyes. After a moment he finished then started looking at Natsu's head. After about 5 minutes he finished and leaned back while letting out a tired sigh. Both kids seeing this couldn't help, but voice their concern.
" What's wrong jiji?" Konan and Natsu asked at the same time.
"Well to answer your question, Natsu you have multiple seals placed on you. These are affecting your memory, your body, your abilities, and few other small things. The person who put them on was the one who kidnapped you when you were young. I'm going to remove them ok, this is going to be painful ok?" Nagato while looking his grandson in the eye.
"It's ok Jiji I trust you. Do what you need." Natsu says while smiling at his Jiji. Nagato couldn't describe the feeling knowing that his grandson trusted him this much despite just meeting him. Taking a deep breath, Nagato put his hands on Natsu's chest as he said two words that would later effect all of earthland.
"Seal Release!" Nagato said as Natsu was surrounded by a deep purple aura as seals started showing up all over his head and chest. On his forehead there was a memory seal and a mind suppressing seal, on his chest was a stunted growth seal, an appearance seal, an ability seal and finally a dead mans seal. Once all the seals where revealed the purple aura around Natsu started flooding the seals, shattering them. Like a switch was flipped Natsu started to scream in agonizing pain from his body being subjected to 18 years worth of suppressed physical traits and suppressed memories. While this was happening Nagato couldn't help, but grit his teeth at the pain he was causing his grandson pain. Konan was in tears listening to the heart wrenching screaming coming from her little brother. Finally after nearly ten minutes the screaming stopped and laying there was a completely different person.
Originally Natsu was 5' 9", had spikey pink hair, olive green eyes and had a very lean defined muscular build. The man before them stood at an impressive 6'4", his formally spicy pink hair was now red like all uzumakis and which goes down to the shoulder, he was more muscular similar to Gajeel, but retained the definition he had. When Konan same the new Natsu Uzumaki she had to pinch her nose to stop the massive nosebleed she got. Nagato only looked at his grandson with pride and silent fury at the man who put those seals on him.
