It is spring of 791, and over 6 years have passed since the Fairy Tail Guild was attacked by the Dragon King Acnologia on Tenrou Island, with many of their members going missing.
A ship is currently sailing towards the estimated location where Tenrou Island used to be, with many Fairy Tail Guild members such as Alzack Connell, Bisca Connell, Warren Rocko, Max Alors, Jet and Droy being on board the ship.
So far they have not found any signs of Tenrou Island, despite having looked for it for some time, until one of them sees a person flying above the waters far out in the distance.
"Is that a person?" asks Max, not believing his eyes.
As the ship comes closer to the person, so that they can see her clearly, they see that the person in question is a cute girl with long blonde hair, dressed in a white dress, who then starts making hand gestures with both of her arms, which causes a sphere that is surrounded by golden light to come out from under the waters.
After the light around the sphere dies down, the people on board of the ship see that inside the sphere was the Tenrou Island they have been searching for.
The girl, having undone her spell, now has a shocked look on her face, so she turns around and starts flying towards the island at a steady pace, which they would able to follow.
"Quickly." shouts one of them, having understood her actions as her leading them to something "Let's follow after her."
As they follow the girl for a while, she suddenly stops, making the others do the same.
They then see a blonde-haired young man who looks like Natsu Dragneel sleeping on the rocky terrain, being dressed in different clothes than the ones he left over 6 years ago, while having his signature scarf lying next to him.
"Is that Natsu?" asks Bisca, while thinking 'What happened to him?', so she shouts out to the others "If he is alive then it is possible that the others are also. Go out and look for them." they do as they are told, while Alzack and the young girl decide to remain with Bisca, so they could protect her if this person is not Natsu but an enemy who looks like him.
Bisca then starts shaking the now blonde-haired Natsu, causing him to start waking up from his sleep while mumbling 'I was having such a good dream.'
Natsu then opens his blue eyes and sees an older-looking Bisca looking at him. "Bisca?"
"Who are you?" asks the blonde haired girl who led them to this location, as only she knows that Natsu Dragneel had died 6 years ago.
Natsu then sighs and replies to her question "I am still Natsu Dragneel. But first gather the others, so that I do not have to repeat my words to them."
After the Fairy Tail members have all woken up, and were told about their circumstances, they have now all gathered around Natsu.
Gray Fullbuster decides to be the one to ask the question they have all been thinking:
"What happened to you flamebrain? Why do you have blonde hair now?"
Natsu decides to explain to them what happened to him after the Fairy Sphere was cast on them and what the Prime God told him, while the blonde haired girl, now identified as Mavis Vermillion by their guild master, supports his side of the story by telling them Natsu Dragneel mysteriously died 6 years ago.
Many of them easily believe in his story, as the explanation makes sense. Gray Fullbuster then starts taunting him by calling him a weak stupid blonde, causing Natsu to hit him in the face with a Fire Dragon Iron Fist, knocking him unconscious and proving to most of them he is indeed Natsu Dragneel, while Mirajane and Gildarts are still being suspicious of him thinking he could still be an impostor, but Makarov Dreyar assures them that he can not sense any evil intentions from the new Natsu and that Natsu does not appear to be lying to them, making the others finally drop their guard around him, with Mavis confirming his statements.
When they arrive in front of the Fairy Tail guild hall in Magnolia, which is now much smaller than the one they are used to, Natsu kicks open the doors and shouts out "We are back!"
"Still the same old Natsu." smiles Erza Scarlet, seeing that Natsu is still deep down the same Natsu they all love.
The current Guild Master, Macao Conbolt, who was drinking his beer, drops his mug, while having tears in his eyes "Welcome back everyone."
"Everyone," says Makarov, seeing their happy faces "Let's party!"
Many hours later as most of the members are still celebrating their return, Lucy Heartfilia is sitting at the table with Happy, Cana Alberona, and Erza Scarlet, who is currently eating her strawberry cake, while Lucy has an amazed look on her face, as she is looking at the new Natsu, who is busy eating his food at a much slower pace, showing to them his perfect table manners fitting of a noble "Since when did Natsu show any table manners?"
"Aye!" shouts Happy, as he agrees with Lucy, while not knowing much about the Phenex family as Natsu did not think it was important to include it in his story when he told them what happened to him on Tenrou Island "Natsu has become weird."
Erza stops eating her cake and puts her fork on the table, saying "It is nice to see that he has finally grown up.", thinking such table manners are normal.
"I wouldn't be so sure of that, Erza." interrupts Cana, thinking Natsu knowing table manners has not changed him as a person "I bet he is still the same kid he was before."
"You could be wrong in your assumptions." replies Erza, having a grin on her face "He did have more years than us in order to grow up after all."
"Wanna bet?" asks Cana, while making a suggestion "10 000 Jewels?", hoping to make some easy money.
"Deal." replies Erza, having agreed to the bet with Cana by shaking hands with her.
Cana then goes over to where Natsu is, while the others at the table are watching as the events unfold before their eyes from the distance, only for Cana to return after a few minutes with a red face, while handing over the Jewels to Erza.
"What happened?" asks Lucy, now being confused.
Cana starts laughing and replies "I started to flirt with him, thinking he is still the naive Natsu as before, only to have him start flirting back at me."
"Really?" asks Lucy, not expecting this kind of change from the dense Natsu Dragneel, while thinking 'Or would he prefer to call himself Natsu Phenex now?'
As they were talking about Natsu's change, Makarov Dreyar, who has once again been chosen as their guild master, shouts out to the guild members "Attention please!"
Everyone stops what they are doing and turns their attention to their Guild Master in order to hear what he has to say to them.
"I have decided that Fairy Tail is going to compete in the Grand Magic Games this year." declares Makarov, while getting confused faces from their core members, while terrified looks from those who were left behind "For those who are wondering, it is an annual competition held in order to determine the strongest guild in Fiore, created while we were frozen in time. With the winner getting awarded 30,000,000 Jewels!", while having money signs in his eyes. "As such I wish for you all to go train and return to the guild after three months have passed, which is enough time before the competition takes place. Then I will declare the team who is going to represent us in the competition that is being held in Crocus."
'Interesting.' thinks Natsu 'should be a good way to determine how strong I am compared to the other mages in Earthland.'
Natsu finishes his food and drinks all his remaining wine in his mug, while placing the empty mug on the table, and thanks Kinana for the good food she had made for him.
He then stands up, and starts to make his way towards the table where he sees Happy listening to Erza, Cana and Lucy talk, causing the three to stop talking after seeing him.
"Happy." says Natsu, having arrived in front of their table "Ready to go home with me?"
"Aye!" replies Happy, and starts to follow Natsu out from the guild towards their house in the woods.
As they are walking towards the location where their house is, Happy asks him a question "Since when did you know how to flirt with women, Natsu. I thought you were stupid."
Natsu being annoyed at being called stupid by his adoptive son decides to reply "Well, Happy. Since I originally did not live through puberty before being resurrected by my own brother as a demon, my body also never completely matured into adulthood. Now that I have matured into an adult, my body starts to react while being around attractive women."
"Oh no!" shouts Happy, while acting scared "Does that mean that you will now be going around kissing random women on the streets?", trying to make it a joke.
"Maybe." replies Natsu, as he is thinking about his encounters with a few women in the Underworld while chuckling "It is quite possible that this may happen.", thus scaring Happy.
After they have arrived in front of their house, they see that the house is in a bad condition due to having been abandoned for 6 years and they will likely need to do some renovations in the future. 'Better yet,' thinks Natsu 'might as well buy ourselves a new house.', knowing that he could easily get a huge amount of money if he starts making and selling Phoenix Tears in Fiore 'Good thing that it is still livable for the time being.'
Natsu then finds his hidden key, and opens the door of their house, while turning around to look at Happy.
"Happy." says Natsu, getting his attention "We will be going off to train tomorrow morning for three months. It will only be the two of us. We can use this trip as a father-son bonding experience."
"Aye!" shouts Happy, seeing nothing wrong with the idea, and starts making his way towards his bedroom "Goodnight Natsu."
"Goodnight Happy." replies Natsu and does the same.
Authors notes:
Natsu is currently not in a relationship with anyone, but he is not a virgin. The story is rated T because I doubt I will ever write any lemon scenes.
Natsu is stronger than Gildarts, while having the strength of an average Ultimate Class Devil, while still having only a small chance of defeating Acnologia, due to Dragon Kings even on Earthland being close to Satan-class in strength in this fanfiction. The 3 months training trip will make him much stronger, in addition to having his second origin opened before the Grand Magic Games. After another 1 year training trip following the defeat of Tartaros, he will reach Satan class in strength.
When the original Natsu Dragneel died, the Prime God put Igneel to sleep and transferred Igneel's soul over to Natsu's scarf.
Natsu's Fire Dragon Slayer magic differs from his previous dragon slayer magic as he will not have a dragon seed inside him and can no longer enter dragonforce. He could only learn Fire Dragon Slayer magic with the help of Tannin due to that magic having become a part of his soul and his Phenex hellfire adapting to the magic, by taking on the properties Dragon Slayer Magic over time, so basically his magic is hellfire that has taken on the properties of dragon slayer magic.
If you calculate the timeline, then Fairy Tail members were missing for 6 years, not 7 years. Acnologia attacked Tenrou Island on December 16, X784, and they returned at least 3 months before the Grand Magic Games were held, which was on July 1–7, X791.
Pairings are currently undecided, but possibly a harem with multiple women from both Fairy Tail and High School DxD.
