Summary: What if Kayaba Akehiko had a little sister, who was very talented in AI programming. She helped him to create a AI which is able to invent NPC and new Quest, that the game get on one hand more unpredictable and on the other hand would never end. In this story Kayaba didn't intend to trap the players in the world, he just wanted the best MMORPG. Further with this kind of AI he wouldn't know all Quests either.

Chap 1 The Prologue

"Alright I made it" exclaimed Yui. Kayaba turned hi head around to take a look onto her computer screen. It showed a lot of complicated calculations. Kayaba looked over them and raised his eyebrows. He could describe his sisters work with just one word ingenious. He still couldn't believe that something like this was even possible. Yui had created an AI which was able to program itself. It was an AI which could extend its code to be able to sort out arising problems in the program -code. So it could react to everything thrown at the system and could react to every little bug. So there wasn't any need of a game-master for SAO any more then the System itself could do a better job then any human. For Kayaba there was only one thin left to do. He had to specify some master-rules that thy system could-not change completely.

The created castle aincrad must not be changed.

There may be added dungeons Quests and NPC but the structure must stay the same

All players are to be treated equally

Each floor has a recommended player level, NPC must not exceed this level by more then 10

In the castle Aincrad the player level must not exceed 100

All values for monster-drops, monster-respawns, NPC-Quests, Quests must stay in their initial setting.

The save area of the main cites in each floor must not be changed

The system must stay divided into Cardinal, bug-finding, and user-assistance programs which must act independently, but there must be a deep cooperation between these programs.

Every program which is listed on the white list must not be deleted must have the ability to run when needed (which is declared in its parameters).

The system has to follow its own parameters and may not change them.

After a fem minutes Kayaba finished entering the rules into the main program. He added some important security rules to let the system detect foreign software and to defend itself against hacks and cheat attempts.

"I think that is all" Kayaba said more to himself. Yui looked at their work. "The first VRMMORPG, the first game which doesn't need a support-team the first game which is not bound to human fantasy and will grow on its own as long as enough hard-drive space is available. I have to say brilliant work from both of us." She exclaimed optimistically.

Soon was the day of the release. This AI was the last new thing they had created for the launch of SAO. The knew everything else worked perfectly. 1000 players had tested it in the closed beta and the game scored perfectly on all top-lists. There was one problem, the couldn't support many more then 10000 players so only this amount of copies were sold. Kayaba started the game and lay down on the special bed. Then he put on the nerve-gear and dived into the game. He wanted to check everything again before it came to the day of the release.

Time skip—a few days later

Today was the big day, today was the game launching. All copies of the game were being sold after some minutes and there was no doubt that these 10000 players would be online when the game starts. Kayaba and Yui had checked everything and were sure that everything worked properly. The hoped that the server could take 10000 players logging in at the same time, but it shouldn't be much of a problem. The both agreed that Yui would stay outside and Kayaba would start playing with all the other payers and she would join later. Now the only had to wait for the time to pass and for the best game to begin. That it would soon turn into the worst game they didn't know.
