Auld Lang Syne
By Muphrid
"Because she was afraid, she decided she couldn't help clear SAO, but her friends kept trying anyway. They kept trying, and they died for it. Still, she's safe now. She could wait for others to clear the game and send her back home, but just as she couldn't stand that fear before, she can't stand being so safe now. Her name is Sachi, and she's picking up her shield once again."

The Nightblade series
By KnightEstoc

Book 1: "Kirito? Asuna? They've got it made - fighting skills, popularity, notoriety... the list goes on and on. And who's that, in the back of the frame, just slightly out of focus? Why, that's me, of course. I've got intelligence, and that's about it. Surviving the Death Game's gonna be tough."

Book 2: Wings of Vengeance
"We're back from Aincrad. Well, most of us. 300 players are still asleep, and of those 300, only one matters to me. So when I find out something that might be the reason why Asuna's still asleep, what the hell do you expect me to do? Stand by and watch? Hardly. I take what I want, and right now I want her awake. Nothing will stop me or Kazuto from accomplishing that goal. Nothing."

Shared Strength
"They say a true friend is someone you can rely on when everything seems hopeless, and for Shino, that person was Kazuto Kirigaya, her best - and only - friend. But Shino didn't want to rely on Kazuto as much as she did, so when beta testing opened for a new game called Sword Art Online, she submitted an application..."

Double-Edged Sword
By Frog-kun
"Kirito's dual sword wielding ability turns out to be a double-edged sword when the rest of the SAO players think of him not just as a Beater but as someone who has a connection to Kayaba himself. It's not just the PKers who are out for his blood..."
