The war between elves rages on, with Kirito and Asuna caught in the middle! The forest elves seek the dark elves' Secret Key, but to what end? Though Kirito tries to stay detached, Asuna can't help being swept along for the ride. Kizmel is supposed to be just an NPC, right? But then why does she seem so very human...

While Nezha attempts to atone for his misdeeds, the battle against Sword Art Online's second-floor boss begins! Kirito's uneasy alliance with the other front-runners seems to be holding, but what will happen when the floor boss corners them? Can Nezha rise to the occasion and seize a hero's prize?

The mysterious player Morte has manipulated the human guilds into fighting BOTH side of the Elf War! While Kirito challenges him to a duel, Asuna has an important task of her own: steal the battle plans from the Forest Elves so she can end this quest before it turns deadly. They need to stop the war before someone loses their life--permanently!

Yuuki Asuna was a top student who spent her days studying at cram school and preparing for her high school entrance exams--but that was before she borrowed her brother's virtual reality game system and wound up trapped in Sword Art Online with ten thousand other frightened players. As time passes, Asuna fears what will become of her life outside the fantasy realm--the failure she might be seen as in the eyes of her peers and parents. Unwilling to wait on the sidelines for more experienced gamers to beat the game, Asuna employs her study habits to learn the mechanics of the game--and swordplay. Her swiftness impresses Kirito, a professional gamer who invites Asuna to join the best players on the front line. Is Asuna ready to swap class rankings for player rankings and join Kirito?

After reaching the second floor of Aincrad, Asuna decided to have a player controlled blacksmith upgrade her beloved sword, a rare Wind Fleuret--but when the unimaginable happened and the sword was shattered in the attempt, Kirito suspected foul play. Did the blacksmith really just happen to destroy an incredibly valuable item? And if not, is there any way to get it back? And--if there really is a conspiracy of thieves--how can they be stopped before they spread too much mistrust? The game of death is bad enough already!

It's time for the 'real' SAO--the third floor! Kirito and Asuna are hardly out the door when they stumble upon the start of the Elf War quest. When they decide to side with the elite dark elf Kizmel, they're set on a path that will push them harder than ever before. But together, nothing can stop them...right?

The party is shaken when their leader, Diavel, is struck down by the boss of the very first floor. Asuna and her teammates are confronted for the first time with the cruel reality of their situation: Sword Art Online is no mere game--death here is final. Their commander lost, the remaining fighters begin to lose heart and plan their retreat. But the fight must go on if they are to escape this game world, and in his dying moments, Diavel managed to convey his appointment for the next commander--Kirito!
