Where Ends Meet (A Sword Art Online oneshot fanfic)

In this AU, Kirito never faced off against Heathcliff on Level 75. They continued on for the next year and a half, reaching level 100, where Kirito, Klein, and Asuna defeat Heathcliff and end the game. Less then five thousand players are alive at this point. Kirito turns 18 the day they finish the game.

Also, Kirito managed to hack the game (after a lot of practice) and create a character for Yui, using his and Asuna's NerveGear to house their daughter to avoid deletion. Yui lived with them the entire time. But, on completion of the game, it became impossible to communicate with Yui, and Asuna became stuck in an un-game-related coma.
