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?

It's been just two months since they were trapped in the game of death that is Sword Art Online, and Kirito and Asuna continue their struggle at the vanguard of progress through the game. The fifth floor of Aincrad is a mazelike ruin, and the two dare to take pleasure in raiding it for the treasure it contains. 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, for in doing so they will have to face her least favorite monster ever...

"There's no way to beat this game. The only difference is when and where you die..." One month has passed since Akihiko Kayaba's deadly game began, and the body count continues to rise. Two thousand players are already dead. Kirito and Asuna are two very different people, but they both desire to fight alone. Nonetheless, they find themselves drawn together to face challenges from both within and without. Given that the entire virtual world they now live in has been created as a deathtrap, the surviving players of Sword Art Online are starting to get desperate, and desperation makes them dangerous to loners like Kirito and Asuna. As it becomes clear that solitude equals suicide, will the two be able to overcome their differences to find the strength to believe in each other, and in so doing survive? Sword Art Online: Progressive is a new version of the Sword Art Online tale that starts at the beginning of Kirito and Asuna's epic adventure--on the very first level of the deadly world of Aincrad!

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!

Kirito, having explored the latest beta test, has a pretty good idea of what to expect from the newest SAO launch. With Asuna along, the pair hope to experience the official playthrough together, but there's something about the release that's a little different from before...Certain unexpected tweaks from the previous version have Kirito and Asuna tackling a flood of puzzles anew!
