The story of Kirito and Asunas adventure from the very beginning it's au and might have some ooc. Rated m for a reason

Rather than a castle floating in the sky, Kayaba Akihiko has created a world where the dead refuse to stay put in their graves. Players fight to reclaim Aincrad, a massive city spanning 100 districts, from the grasp of the undead. But when they find themselves trapped in this nightmarish world, zombie-hunting ceases to be all fun and games. Welcome to SLD. Follows Kirito and Sinon.

Kayaba Akihiko once dreamed of actualizing a world of swords, a floating castle, a fictional fantasy. But people change and Kayaba is no exception. Players welcome to Gun Gale Online where guns rule supreme and swords are obsolete... well unless you're Kirito that is.
