I am natsu

Training

After the talk with the girls and natsu went to search for a temporary inn because he already determined to buy and build a house for his and his future wives and he is going to search his sister and have lots of fun and adventure.

Time skip:-

It's been a weak natsu joined fairy tail he was doing some low level quests to get a quick promotion in ranks after quests most of the time he spends with the girls who for some unknown reason attached to natsu who was like a pillar for them and who understands them.

Natsu already rose to c rank due to his magic power and work progress so everyone was happy.

Today he promised the girls to train and teach them how to improve their magics.

Natsu: ok girls today I am going to show some magic control techniques to develop large amount of magic.

Grayfia: natsu Kun what is the benefit of the technique you are going to show us.

Natsu: you see fia chan without a strong body and good control a mage even having a strong form of magic will easily loose in any real time danger. Even a novice mage with good control and talent could defeat this kind of mages.

Natsu: first we should build out body and we are going to store ether nano inside our body not only in magic container but all over the body.

Lisanna: how can we able to store ether nano natsu Kun.

Natsu: ether nano is a form of energy if we develop our magic container to maximum capacity an additional container will born inside us so training our body to a certain point we are able to store all the ether nano into various parts of our body with simple methods like talking, breathing etc....

Mira: ohh! So we will be able to easily store and use the ether nano and don't have any magic reduction during missions.

Natsu: Right Mira chan so we are going to build our body and I will open all of your natural second containers which will hurt you at the beginning but it will help you in future.

After that natsu helped the girls to open their second containers which hurt them so he casted a healing spell while they adjust the change of new magic containers.

Natsu first told them to use their strongest spells and empty their containers so the can do physical training.

Mira and erza were the first people to do followed by Cana, grayfia and lisanna.

Natsu then made them to increase their stamina with exercises which they did with certain difficulties but due to natsu's encouragements they did it.

Natsu then healed them with his magic and told them to rest which he prepared several methods to develop their individual magics.

First was Mira he told her to sync with demon souls by dominating them he told her to meditate to control a take over one should have a strong mental power and will to succeed.

So Mira took the advice to the heart and started to meditate to control her emotions and mind.

Next was erza he told her to have different sword styles for different armors will not help her so she should create her own style by making her armors and weapons as a extensions of her body.

Erza nodded and started to close her eyes and visualize her own sword style.

Next was Cana he told her to use a variety of cards with different offensive and defensive spells to fight her enemy's but she should not relay on her magic and be vulnerable so he would teach her a form of offensive magic which he think will suite her.

Cana asked what kind of magic he would teach her the answer which he gave her made her paralyze because natsu told her he would teach her crush magic which was her father's magic.

Natsu asked her which she froze for a second but she diverted the issue by telling him she doubt it would suite her but natsu told she have a natural affinity for that magic it will suite her best which made her smile.

Natsu knew she could hesitate to learn her father magic but wanted to help her so he told her to practice some magic release methods to which she nodded and went and he helped grayfia and lisanna to increase their magic output and the training went on until dawn and Natsu hunted a mana beast and started to cook for the girls in outdoor.

After eating natsu's cooking all the girls had a pleasant smile and natsu also smiled at them which made the girls attract natsu even more.

natsu and girls continuously improved on their magic and styles which was noticed by makarof who was happy for the growth of the children and grayfia dress striping habit was totally gone which made her happy.

All the guild mates noticed that the group of girls attached so much to natsu some were started to bet which girl will first going to confess to natsu which made the girls blush crazily at the thought of confessing to natsu.

Natsu was not the dumb Shonen protagonist who was obvious to the feeling of other girls around him. he perfectly know all the girls are in love with him. he also love the girls and protect them till his last breath.

natsu on his last world where he couldn't find girls who love him for him not for his money was happy to have this wonderful girls to be with him if  they are going to be his he will treasure and shower them with lots and lots of love and make them happy and cure them from their external nightmares.

Natsu when ever he goes to missions he would get souvenirs for the girls every time whether it is magic items, dress or other ornaments for the girls he would buy them for them.

other girls in the guild are envious of the group of girls because they don't have person like natsu to pamper them every one in the guild know the girls are madly in love with him and he also love them have a strong possessive side for them if any girls with lust and other ulterior motives come near natsu the girls become aggressive with them same could be said to boys with lust will receive a beating from natsu.

natsu do his mission easily and without damages earned a good reputation for himself same could be said to girls developing names across various jobs. ElfMann come and asked natsu to train him which he accepted whole heartedly and the MAAN! was born due to ElfMann nature to want to protect his sisters showed.

And a year passed after natsu joined the guild the girls had a meeting and agreed to share natsu and don't want some harpies to hit on their man confessed to him which he accepted whole heartedly and kissed them which made the girls blush like tomatoes.

( Natsu age is chronologically 407 when he passed through eclipse gate while we don't know what happened between natsu(E.N.D) and igneel before zeref took him to igneel to learn dragon Slayer magic. Mardgear said E.N.D was the ruler of hell before getting sealed by zeref in anime so my thoughts are that Zeref first created the adult version of natsu E.N.D to kill him who must had pure demonic power after the failure of E.N.D by not killing zeref he reverted the E.N.D and try to bring back natsu to the body of the young self that's why we couldn't see a chapter between E.N.D vs igneel it was stated that igneel had power to kill E.N.D but he didn't kill him because of the love he had with natsu on some point of dragon Slayer training E.N.D must have resurfaced on natsu's body so igneel only left him defeated and zeref sealing all the consciousness of E.N.D from him in war arc E.N.D was released due to natsu thinking Lucy was killed by daimara.
