Kirito jumps into a new VRMMORPG called ALfheim Online (ALO) in search of Asuna, who still hasn't regained consciousness. On his quest to find the World Tree and reach Asuna, he meets a sylph girl named Leafa. A veteran player experienced with the sword, Leafa recognizes that Kirito is motivated by serious circumstances and decides to help him. But...Leafa's identity in the real world is Suguha Kirigaya--Kirito's sister. And it's the glimmer of her beloved brother she sees in Kirito that prompts her to lend him a hand. Now, despite the conflicting interests guiding them on, the pair set off on a journey to the World Tree!!

Kazuto Kirigaya (aka Kirito) has beaten Sword Art Online, a VRMMORPG that transformed into a literal game of death, and returned to the real world. Unfortunately, the same cannot be said for Asuna Yuuki (aka Asuna the Flash), the girl with whom Kirito fell in love in the virtual world of Aincrad but who has yet to awaken from her game-induced slumber. As his sister, Suguha, sadly looks on, Kazuto continues to visit Asuna in the hospital in the hope of finding answers. But when one day he meets a man claiming to be Asuna's fiancé, Kazuto fears that Asuna may be lost to him forever... That is until a fellow survivor of SAO taken form the latest VRMMORPG sensation, ALfheim Online - a screenshot that features someone being held captive who looks entirely too much like Asuna! His hope renewed, Kirito dives headlong into an all-new virtual adventure, but can true love conquer the game?!

Having defeated General Eugene of the salamanders and aided the alliance between sylphs and cait siths by protecting their leaders, Kirito and Leafa reach Alne, the town at the foot of the World Tree, at long last. But before they can tackle the tree--and their main objective--server maintenance begins, and they are forced to log out. Back in the real world, Kazuto and Suguha Kirigaya, each unaware of the other's in-game identity, pay a visit to Asuna Yuuki, who still lies asleep in her hospital room. While there, Suguha suffers a terrible shock when she realizes just how strongly her beloved brother cares for Asuna. Meanwhile Asuna, still imprisoned atop the World Tree within the game world of ALfheim Online, sets her escape plan in motion... The adventure in ALO finally reaches its climax! Enjoy the conclusion of the Fairy Dance arc in this massive final volume!

Kirito has entered the new VRMMO Gun Gale Online in order to investigate the Death Gun incidents, only to discover his avatar is not exactly how he remembers it! He barely knows up from down in this new world, and he needs an ally. He may have found one in the mysterious female sniper Sinon, but she's got an agenda of her own...

Sword Art Online, the world's first VRMMORPG (Virtual Reality Massively Multiplayer Online Role Playing Game), may have started out as a game, but it has since become a matter of life and death for the ten thousand players trapped within. Two years after game programmer Akihiko Kayaba's chilling declaration--"This might be a game, but it's not something you play"--the number of players has dwindled to six thousand, and for many, every day is a struggle for survival. Though Kirito has stayed alive by making a name for himself as a solo adventurer in that time, his life undergoes a major change when he unwittingly joins Asuna's powerful guild, the Knights of the Blood. What does fate have in store for Kirito, Asuna, and the brave young fighters who are risking their lives to return to the real world?!

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!

A year after Kazuto and Asuna escaped from Aincrad, the deadly setting of Sword Art Online, they're still coping with the aftermath as they try to recover from the harrowing experience. Meanwhile, there's a new VRMMO game sweeping the world's gamers--Gun Gale Online. When a mysterious player who calls himself "Death Gun" claims to be responsible for real-world deaths, Kazuto (aka Kirito) is recruited to enter the game to investigate, bringing an end to his hard-won peace!
