Sword art online / Kawahara, Reki

Kirito and Asuna get to the fourth floor, which has been changed into a water world, and in order to get a gondola to navigate it, they must confront an eight-meter-tall beast of flames.

"The Elf War 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..."--Back cover.

"It's been just two months since Kirito and Asuna were trapped in the game of death that is "Sword Art Online," and they continue their struggle at the Vanguard of those trying to clear the game. The fifth floor of Aincrad is a maze of ruins, and the two dare to enjoy hunting for its treasure. Upon returning to the fourth floor, it's time to do some questing on behalf of the elf lord Yofilis--but here begins Asuna's discontent, because now they will have to face her least favorite monster ever..."--Back cover.

"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?"--Back cover.

"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 iwa 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 is a conspiracy of thieves--how can they be stopped before they spread too much mistrust? The game of death is bad enough already!"--Back cover.

"While Nezha attempts to atone for his misdeeds by completing a quest to learn the Martial Arts skill, Asuna toils alongside him for her own reasons--and learns a troubling truth in the process. Meanwhile, Kirito's uneasy alliance with the other front-runners seems to be holding, but are they really ready to face Sword Art Online's second-floor boss? And if the Legend Braves are neither legendary nor brave, can Nezha still rise to the occasion and seize a hero's prize?"--Back cover.

"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?"--Back cover.

"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 ... 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!"--Back cover.
