Hello and welcome back to another chapter. Before we get going I would like to apologize for taking so long to update any of my stories. Right now the Finals are coming up soon for my college courses and I have even less time to work on my stories than I had before. Not to worry, I will continue to work and update my stories so please be patient. That's all I have to say right now so, Let's get started.

Fire Dragon's Iron Fist

Gremory Courtyard

Once again we return to the courtyard where we find a small group playing games, running around, and having a fun time. Having just shown off his magic to Sona earlier, Natsu was off to the side sitting underneath a tree recovering from the fatigue of using his magic, watching the two heiresses play tag.

Flashback

Gathering in the opening of the courtyard, Natsu awaited Sona and Rias' arrival having sped past both of them on the way over from the lounge. After a few minutes, both heiresses had finally shown up, sweaty and exhausted, but still conscious. "Finally, alright are you ready to see some of my magic?" asked a rather eager Natsu. "H-hold on just let me catch my b-breath." Responded a fatigued Sona. Not even a minute later, Sona recovered and informed Natsu that she was ready to see what he could do. "Alright, Here I go." Said Natsu before he made a small magic circle with his left hand, pointed to the sky, and shot up a few small fire balls that later exploded into fireworks. "WOW, Natsu that was amazing." Replied an awed Sona. As she continued to watch Natsu show off some more of his magic, Rias informed her as to what kind of magic Natsu uses, as well as gave her some info on the extent of his abilities. One impressive fire display later, and Natsu was left quite exhausted, and Sona star-struck. "O-Okay, I-I'm done, so w-what do you think?" said a tired Natsu. "That was beautiful, to think you could do all that. I have to admit I am impressed." Replied Sona. Natsu simply gave her a small grin before passing out from exhaustion.

Flashback end

"Hey Natsu, come-on we're heading back inside." Called Rias. "Sure thing, I'll catch up." Natsu called back. Standing back up he quickly rejoined the heiresses as they were on the way back to the lounge where to rest of the family was.

Gremory Lounge

Having returned to their families once more, Sirzechs welcomed them back before turning to Sona and asking her how the magic show went. "It was quite a wonderful display. I've never seen someone using magic the same way Natsu does though." Laughing at her answer Sirzechs was about to speak up, when someone abruptly cut in.

"WHHHHAAATTTT? YOU GOT TO SEE THAT PINK-HAIRED CUTIE'S MAGIC AND DIDN'T TELL ME." Shouted an extremely jealous Serafall. While Sona attempted to and failed to calm her elder sister, Sirzechs pulled Natsu and Rias off to the side. "Is there something you need to tell us Onii-chan?" asked Rias. Nodding in confirmation, he replied "The time draws near where you two will soon be High-Class devils, (Even though he's technically a half-devil, the class system still applies to Natsu) both kings of your respective peerages. But before you become a High-Class devil, you need to take and pass a mandatory exam. Natsu, I do believe you asked me if there was someone who you could train with to get stronger. Earlier this week, I was able to get ahold of someone who will be able to help you improve your powers tenfold."

At this newfound information Natsu started to cheer. Smiling at how happy the boy was, Sirzechs went back to a stoic expression before continuing "However, during the time you spend with my contact, he has made it clear that you will be with him for the entire time until the date of the exam which will start in 4 months' time. Which means that Rias won't be able to go with you or visit you for said period of time." When they finally processed his words, the two children looked like they were about to cry waterfalls, before taking a glance at each other and bringing each other in a tight hug. Clearly not wanting to have to leave the other.

Sighing internally, Sirzechs mentally prepared for the migraine he was sure he was going to get as he spoke up once more. "I know that you don't like it, but that is what the rule is if you want to train under him. If it was up to me I personally wouldn't mind if you two trained together, however my contact refuses to train anyone else during the time he will be spending training you Natsu."

Barely able to recompose himself, Natsu released himself from his hold on Rias, before looking directly up into Sirzechs' own eyes and giving his answer. "If that is what has to be done in order to help me get stronger, then I will accept his terms." Smiling at the young boy's determination, Sirzechs recommended that Natsu better go start packing for the trip.

Not even a minute had passed when Sirzechs and the two Gremory siblings were brought back into the rest of the family where the Sitri sisters, having resolved their minor dispute minutes earlier, announced that the time they had put aside for the visit is over and they will be leaving shortly. "I guess this means good-bye, Natsu-san." Said a rather sad Sona. Wanting to cheer her up, Natsu gave her his trademark grin, making her cheeks turn redder than Rias' hair, and then said "I don't think this will be the last time we will meet, so I won't say good-bye. But rather I hope to see you again sometime soon." Once she heard this, had her cheeks not been colored before, they were surely even more prominent now than ever. Leaving her a blushing mess. If one were to listen carefully, they could barely hear Sona mumble out something along the lines of thanks. Serafall on the other hand, had other ideas of a good-bye, mainly in the form of attempting to steal one pink-haired devil and bring said devil back with her, but after much protest from both heiresses, once Sona had recovered, she relented and released the poor devil. With the rest of their good-byes out of the way, the two Sitri sisters made a light blue magic circle before stepping through it and disappearing.

The next day, Gremory Courtyard

Having received word that Natsu's teacher will be arriving shortly, after a quick breakfast, the entire Gremory family gathered in the courtyard awaiting the teachers' arrival. Natsu still in the dark about who his teacher will be, turned to Sirzechs and asked him why they were all gathered in the courtyard. "Well Natsu, your teacher is rather massive in size, so if he were to try and meet us inside the manor, there is no way he would actually fit inside without destroying everything." Said Sirzechs.

The vague answer about who his teacher was, didn't help Natsu in the slightest, if anything it left him with more questions than answers. But before Natsu had a chance to give another question he was interrupted by something he thought he would never hear again. A dragon's roar to be precise. If one were to try and describe how much shock was currently shown on Natsu's face they wouldn't even know where to begin. The sound of large wing-beats, drew Natsu's attention to the sky, what he saw was nearly indescribable. Up in the sky was a Massive dark-purple western dragon. The horns on the head were curved forwards and were a faded yellow in color. Most of the dragon's underbelly was beige in color, including the upper half of his legs.

Awed by the appearance of a dragon from this world, Natsu could barely contain his excitement. About to rush up to the dragon, he was stopped when someone caught him by the back of his collar, turning around to yell at whoever was holding him back, he paused when he saw that it was none other than Grayfia, who was currently giving him a stern look that promised pain if he didn't comply, to which he did.

"It's been far too long since we've last met in person Sirzechs." Spoke the dragon. Completely unfazed, Sirzechs looked up to the dragon and spoke up. "Indeed it has Tannin, however, now is not the time for idle chat. Knowing how thin your patience is I would like to introduce you to your student." Seemingly content with the response, though not without a low growl, the now known Tannin spoke up once more. "Very well, I would also like to meet this student of mine." At his request, Natsu made his presence known to the dragon, before speaking up. "Hello there, my name is Natsu Dragneel, half-devil of the Gremory family, Fire Dragonslayer, and son of Igneel, the Fire Dragon King." Intrigued and amused at his statement, Tannin thought it only fair to introduce himself as well. "Greetings Natsu. I am the blaze meteor dragon known as Tannin. I had once held the title of Dragon King along with several others, before I gave it up and became aquatinted with Sirzechs here." Rather impressed with the dragon and his former status, Natsu was eager to start his training with the former dragon king. So after a quick series of farewells, as well as a promise to visit Rias, Natsu hopped onto Tannin's back, and the two flew off into the sky.

And there you go, plus one chapter. So now we will be getting into the canon of Highschool DxD so harem and everything you've been asking for will be making their arrival soon. Since this is technically not canon Natsu, though, please try to remember that his powers, personality, and motivations will not be a 100% replica of canon Natsu. The romance has already been seeded, so now you just have to wait and watch it grow. Hopefully everything is up to your expectations and will continue to remain so in future chapters. That's all I have to say so, I will see you when I see you.
