Hello and welcome back to another chapter. Before we begin I would once again like to thank everyone for their continued support throughout the time between posting chapters. I really appreciate the encouragement and that is what I would like to say keeps me writing stories for you. Once again I don't own anything related to Fairy Tail or Highschool DxD. Not much else I have to say so, Let's get started.

Fire Dragon's Iron Fist

Courtyard outside the Gremory Manor 4 years later

A lot has changed during the four years that Natsu spent living as the newest member of the Gremory family. During this time, Natsu's intelligence increased drastically, while still pretty dense about most things, Natsu is a fair bit smarter than the average human, or in this case devil when it comes to things he knows the best. This increase in his knowledge can be given credit to Grayfia who through a rather harsh teaching style, managed to drill a lot of information into Natsu's head. Another new change to Natsu was now he is the first of his kind to become a half-devil half-human. This happened when Sirzechs had tried to make Natsu into a devil so he could be officially recognized as a member of the Gremory family, but due to some mishap that occurred internally, the process was halted halfway through. Though not as skilled as a devil, he still had the wings of one, though one of the wings was that of a devil, while the other wing looked more draconic in appearance, much to the others and his own confusion, after a few flying lessons, Natsu could now fly just as easily as any other devil his age. One new thing to note that while it was well known that a half-devil wouldn't be as powerful as an actual devil, Natsu on the other hand made up the exception, amplified by what devil powers he acquired from the failed transformation, his magic power nearly doubled in size and destructive capability. MacGregor theorized that had the process to turn Natsu into a devil not fail, his magic power would've been on par with Grayfia. However, ever since Natsu's magic power was amplified by the transformation, he found it much harder to control it. Also because of his now half-devil side, he found that while he still could defend against light/holy based attacks rather well, he was still vulnerable to the attacks if enough power was put into the attack. After several rather embarrassing accidents involving Rias, his new favorite sibling, he came up with the idea to train harder to help him regain control of his magic. Speaking of Rias, over the four years Natsu spent living with the Gremory family, both he and Rias grew incredibly close together, and it would be hard not to see the two of them playing together. While neither Rias nor Natsu would admit it personally, everyone could see the love blossoming between the two.

At the moment, Natsu is in the courtyard with Grayfia, the former having challenged the later to yet another spar. The two were currently fighting back and forth, or more like Natsu was throwing everything he had at Grayfia, while Grayfia either side-stepped out of the way of his attacks, or blocked it head-on. Rias was also present this time, sitting on the sidelines and cheering Natsu on. You see this was a regular occurrence between the two combatants ever since Natsu learned that Grayfia was the strongest queen in the underworld. Wanting to surpass her, Natsu had challenged her to a fight. Realizing rather quickly that he would not let it go, Grayfia complied and the two went at it. Though it ended rather quickly with Natsu eating dirt, but that didn't destroy the boy's hopes. Rather it fueled him to grow stronger to surpass her one day. After their first "fight" a few years ago, Natsu had been training long and hard, pushing his body and his magic past their limits. While Natsu was still struggling to land a solid hit on the strongest queen, all that training he did, actually paid off in more than one way. Now not only he physically stronger and faster, he had also adapted an unorthodox fighting style. Combine that with his seemingly genius battle-mind, and Natsu became a tough challenge for almost anyone who he went up against. Another thing to note that while Natsu grew up and became stronger threw his severe training, he had grown out of all the clothes he brought with when he first arrived. One much needed shopping trip later, Natsu's new clothes consisted of a black vest with gold trimmings, a pair of white knee-high baggy trousers, and a pair of sandals. Along with the scarf wrapped securely around his neck, a fire-proof enchantment, and Natsu's new look got him a lot of attention from the female populace, especially Rias and her newfound love for everything and anything anime.

One rather uneventful battle later

As the rather one-sided fight drew to a close, with Natsu once again eating dirt. "Now that that's out of the way, I need to get back to work I will have dinner ready for everyone shortly." Grayfia said, before walking ahead of the two back inside the manor, as Rias went over and picked him up and helped him back inside to his room, which happened to be right next door to her own room.

"As happy as I am that you lasted as long as you did, you should really think more about how to fight rather than jumping right in." said Rias. "Sorry Rias-chan." Replied a rather exhausted Natsu. "Don't forget that this afternoon we are having some special guests over, so make sure to remember your manners." Said Rias. "Guests are coming? How come I didn't hear about it til now?" Natsu asked as he laid down on his bed. "You probably forgot since you were so eager to go fight Grayfia today." She replied.

"That's enough chat, you need to rest up so you can properly meet our guests later." Grayfia said as she walked into the room. "Sorry Rias-chan, we can talk some more later." Said Natsu before he passed out from exhaustion. "Come along Rias, we need to help you get ready to welcome our guests. Once Natsu wakes up I'll fetch him and send him your way." Said Grayfia. "Hold on I'm on my way." Replied Rias, before the two girls left and went to get ready to welcome the guests arriving later.

Several hours later

Having gotten everything ready for the arrival of the guests most of the Gremory family was present in the lounge, this included Grayfia and a few of the staff, as well as Natsu who had woken up an hour ago and helped put on the finishing touches. Everyone was settled in and making idle chat when a light blue magic seal appeared in the middle of the room.

Recognizing the symbol on the magic seal Grayfia decided to tell Natsu about the symbol and said symbol's owner, seeing the look of curiosity on his face. "Natsu this symbol belongs to that of the Sitri family." As soon as she finished that sentence a blur rushed past all of them, straight into Natsu. Taken by surprise, Natsu had caught the blur in his arms, but the force of the sudden stop, caused him to fall down on his back.

Once Natsu regained his bearings he looked down to see a rather beautiful girl who looked to be a few years older. The girl was wearing a bright pink magical girl outfit (best description ever) and was holding a magical wand in her hands that were also currently suffocating poor Natsu. "I should also mention that Serafall Sitri, that girl in your arms, is also one of the four Maou alongside Sirzechs. She just happens to have a lot of energy and loves to meet new people." Grayfia said, as everyone watched Natsu and the now known Serafall "get – to – know" each other, though Rias looked on in jealousy, another person stepped out of the magic seal, before it dissipated. This person looked to be around the same age as Rias and was also a girl. Noticing the way Serafall was behaving caused the person to groan in embarrassment. "Nee-san please let go of him." The girl said, catching everyone's attention.

"Oh? And who might you be?" Sirzechs said. Hearing the voice, the girl turned to face Sirzechs as Natsu was finally released from Serafall's hold. Gasping for air, Natsu turned his attention to the newcomer. He noticed that this newcomer was a lot more composed than Serafall, but also seemed to be her sister due to how similar they looked. As he got a good look at the newcomer, he noted that the sister seemed to be wearing the same school uniform that he and Rias had gone to a few years earlier.

Having noticed that Natsu was staring at her, she started to blush. Trying and failing to hide her blush, she finally decided to speak up. "C-Could you please stop staring at me like that." She said. Realizing what he did Natsu blushed in embarrassment before he responded. "Sorry about that, my name's Natsu Dragneel." Regaining her composure, she spoke up. "I've heard a few things about you from my sister, my name is Sona Sitri." When Natsu realized that someone he's never met til now has heard about him, he wondered how that's possible. Until he realized that his name was most likely brought up by Sirzechs and seeing as how both Sirzechs and Serafall are one of the four Maou, it made sense that he would be mentioned at least a few times.

A few minutes later

Once everyone introduced themselves, they split off in their own groups, with Sona, Rias, and Natsu off to the side of the room, and Serafall and the others from the Gremory family making small talk in the middle of the room. "So Natsu, I heard from nii-chan that you're not fully human nor are you fully devil, care to explain why." Sona asked rather curious. "Well I don't remember much about the process itself, but I do know that something happened midway into the transformation process and Sirzechs and that weird hooded guy, had to shut it down. Luckily I survived the failed transformation and gained some devil traits, so technically, I am one of the world's first half-human, half-devil hybrid." Natsu then took the time to bring out his wings to show them to Sona. Sona upon seeing said wings was astonished to see that one of the wings was that of a devil, and the other looked more like a dragon's. "Wow can you show me what you can do?" Sona said rather shocked at the previous revelation. "Come on, I'll show you some of my magic outside." Said Natsu, as the three kids ran out to the courtyard.

And that's all for this chapter. Thank you once again for waiting. Now the members to Natsu's harem are slowly but surely waving their colors. I will implement the harem soon, so don't worry. For those who are wondering why I made Natsu a hybrid is because while I liked the idea of him becoming a devil like many crossover stories before mine, I also wanted to try something out of the ordinary, so after a little bit of thought, and here's my answer. For those wanting to see more fights, don't worry the fights will come and they will be hopefully up to your requirements. Not much else to say so I will see you when I see you.
