AN: I don't know if there's another story where this happens but I really love the idea of Kirito becoming a Dragon Tamer, like Silica, in SAO albeit with a different dragon so this is that story.

Aincrad's Dragon King

Chapter 1

-Kirito-

"Now what?" he grumbled to himself as he explored the final room in the tomb like dungeon he was exploring, having found a map in the library of an abandoned town which contained a note about a great treasure being hidden within. It had been four days since he had left Klein in the town of beginnings and had begun trying to survive as a solo player in the mad Death Game that was Sword Art Online. The town had been a purely accidental discovery, an area that where before had been a field where mobs didn't spawn that he had planned on camping for the night but instead found a dilapidated town. After sending a message to Argo to spread the word about things having been changed from the Beta.

Message sent he had begun going through the town, looting it of anything valuable or useful as he found a couple thousand Col scattered throughout the various homes and buildings, a few pieces of armor and jewelry which he added to his inventory, and even some weapons which he put aside in his inventory to look through later. The final thing he had found was the map which was in the library which contained several useful books about different skills and quests that could be unlocked. Some he planned to keep for himself and others he planned to trade to Argo to barter for a share of the profit.

In the armor he found a full set of black leather armor, the pieces having been scattered throughout the town, which consisted of a breast plate, grieves, and bracers of the dark leather material. To finish it off he wore a black leather cloak with a hooded cowl. In the weapons he found a better sword than the one he was currently using as well as a good set of throwing knives and a basic bow with arrows which he quickly added to his inventory, bows being a rare weapon in the world of Aincrad, unless that had been changed as well.

The map he had found in the library though had peaked his interest as he quickly tracked down the hidden dungeon that was in the forest, going through the various floors as he delved deeper and deeper into the labyrinthine crypt, each floor containing a mini boss and several hidden niches with chests where he not only leveled his combat skills against the bosses but his detection and lock picking sills at finding and opening the various chests which, thankfully, usually had healing potions in them. Sighing he sat down on a broken column he opened his skills menu and began sorting through his various skills, wondering if he just needed a particular one selected to find the 'great treasure'.

Deselecting his lock picking skill and replacing it with his detection skill he once more began looking about the room before noticing a carving on the wall with a symbol that he recognized from the map…but also different. Wondering if he had to make the symbol look like it had on the map he had found he walked over and moved the various pieces that stuck out of the carving until it was identical to the symbol that headed the map before, as the final piece fell into place, the wall began to shake as it slid apart, dust falling from the ceiling, as a small chamber was revealed with a large black chest in the center.

Readying his sword in case there was one final enemy he approached the chest warily as he tapped it to see if a lock picking menu would open up but, to his surprise, the chest was completely unlocked as he pulled it open, wondering what the 'great treasure' would be but, to his surprise, he could see only a large black shape which, after a moment, he recognized as an egg.

"Is this…a dragon egg?" he asked himself as he pulled the large object out of the chest as he heard a ding and his menu opened up, informing him that he had acquired the 'dragon tamer' skill and that as he leveled it up by training and interacting with his dragon once it hatched his dragon would become stronger and stronger and he could eventually make various dragons obey his commands once he was high enough level.

Grinning widely at the thought of having his own dragon he nestled the egg into the crook of his arm and opened the menu for it, seeing that it would take a full twenty four hours in his presence before it could hatch, and began walking out of the tomb, planning on heading back to the abandoned town to bunker down until his new scaly friend hatched.

As he walked he opened up a chat box with Argo, "Hey Argo," he said as he activated the 'voice typing' function "I have some news you might just be interested in." before hitting the send button as he stared curiously at the plated black egg in his arms.

After climbing up a couple of floors he heard a ding as Argo replied and he opened up the message screen, "I'm still spreading the information about things changing since the Beta but what kind of news are we talking about here?" he read aloud with a grin before reactivating voice typing.

"Several books full of information about various quests and unlockable skills as well as the fact that I now have a very powerful skill of my own…and a bow." He dictated before sending the message.

It took less than five minutes for a reply to come through as he opened the message and read out, "You found what?! How many books? Where did you get them? What Skill? And seriously?! A bow?!".

Laughing in amusement, his mood bolstered significantly by the fact that he had just become a bloody dragon tamer he once more activated the voice type function and dictated "I don't remember the exact number but I found them in a library in a dilapidated and abandoned town where I also found the bow and several other items…which is also how I found out about things changing. It used to be the cove where mobs didn't like to come. And my skill…well right now I have a dragon egg in my arms." Before sending it and clambering out of the tomb, taking a deep breath as he made his way back towards the dilapidated village.

When Argo sent him a message to try to get him to come to the town she was in he sent a different one saying he would be in the small abandoned village until his dragon egg hatched and that she was more than welcome to join him. He reached the town after an hour and it was another three before he heard the thundering hoof steps that signaled Argo's approach.

"Hey Argo," he said happily from his spot on the front steps of the library which was the largest and most central building in the town "you made good time.".

"Don't patronize me Ki-Buo," Argo said with a pout "it was a pain in the ass to get the horse that brought me here. Where are the books and the egg?".

"The egg is here," he said as he pulled it over onto his lap from where he had it set "and the books are in my inventory. Come on, we can look over them at some tables inside.". Walking inside, with his petite friend following him eagerly, he pulled out the various books from his inventory as they stacked up on a table, Argo gaping at the size of the pile.

"Ki-Buo," Argo said wide eyed "you just made me a very happy girl.".

Laughing he pulled one of the books off the pile and sat down, "Well let's go through them," he said "we should find out what sort if information we actually have here to use.". For the next day they went through the various books, evaluating the information within as well as estimating what was worth selling and what would be better kept to themselves as well as going through the armor and weapons he had found, Argo taking a decent set of claws from it in exchange for a favor later on. He eventually drifted off to sleep though partway through their 'investigation' of the books and was shaken awake, somewhat roughly, a few hours later by an excited Argo.

"It's hatching!" she said with a wide grin as he shot to his feet and ran over to the egg and saw glowing red lines appearing on the shell, spreading more and more with each second before the shell burst apart to reveal a bipedal bone plated dragon, its entire body as black as the egg had been, that let out a noise that was a mix between a small roar and a whine as he grinned and placed his hand on the dragon's head, a menu popping up asking what he wanted to name his new familiar to finalize the bonding process.

Noting the dragon's appearance and how it resembled that of a dragon from another video game he had played he typed in "Alduin." With a grin as his familiar flapped over and sat on his shoulder, cooing happily when Argo scratched it under his chin, the little Alduin letting out a gout of black flames which got him and Argo to whoop in merriment.

AN: Yes, his appearance is like that of Alduin and in my story the higher level the dragon is the bigger they grow and they can switch between their larger forms, for combat purposes, and a small form (Pina size) for when they're in cities which is their hatchling size.
