A reunion with Seijirou leads Kirito, Asuna, and Alice back to a version of the Underworld where 200 years have passed since the Great War. There, they find not only the descendants of Ronie and Tiese, but also a man claiming to be the leader of the Integrity Knights, whose eyes resemble his eyes-the one Kirito lost. Meanwhile, in the world of Unital Ring, the ultimate malice targeting Kirito and his friends finally reveals itself!

It's been a month since Kirito and Asuna returned from the Underworld. Together again with Alice, who managed to secure a life in the real world, it should've been happily ever after...But, as luck would have it, the three find themselves involved in a VRMMO by the name of Unital Ring, and all their stats have been reset to level one! It's time for Kirito to put his experience to the test in a genuine Survival MMO!

The protracted secret feud between the Nachtoy and the Korloy families, who control the casino on the seventh floor, takes an unpredictable turn when Kirito and Asuna intervene. But when Kirito attempts to expose the misdeeds of the Korloy family, he ends up stumbling into a trap. Now he has just two days to unravel a mystery, put an end to an unscrupulous conspiracy, and defeat the floor boss. It's all leading up to a showdown in the arena where everything's on the line!

The seventh layer of Aincrad-a massive casino where over half of the game's beta testers dropped out before launch. Kirito, too, lost everything in its Monster Arena back then. When an informant named Argo seduces Kirito and Asuna with knowledge that could aid in their investigation, the pair soon plunge into the casino's dark underbelly once more. Meanwhile, the Elf War Quest also reaches a sudden turning point when a flurry of crises rock the Dark Elves' home!

After two hundred years, Kirito is finally reunited with Selka, Ronie and Tiese, but the girls are shocked to see Eolyne, who bears a striking resemblance to their fallen comrade. Then, with no time to process their feelings, the three Integrity Knights are thrown into battle alongside Eolyne and the Integrity Pilots. The old defenders of the Underworld join the new as the next chapter of the Unital Ring arc commences!

'That's game over, Arita--I mean, Silver Crow.'His life completely transformed since meeting Kuroyukihime, the most beautiful girl in school, Haruyuki has grown up into a magnificent knight, fat and bullied though he might be. As the season turns to spring, a strange new student appears before Haruyuki and his friends, now in eighth grade. This mysterious seventh grader has mastered the art of using Brain Burst in everyday life, despite being curiously absent from the Duel matching list. With Kuroyukihime away on a field trip for the ninth grade class, this new member of the student body, in the guise of a warped duel avatar called Dusk Taker, steals 'something precious' from Haruyuki with overwhelming force. Cast once again to the bottom rungs of the school hierarchy ladder, Haruyuki is driven into a corner, and his only course of action is--?!

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!

Kirito has escaped Sword Art Online, the forbidden VRMMORPG of death, and returned to reality. He heads off to find his game partner and lover, Asuna Yuuki. But Asuna never made it back from the nightmare. Lost and desperate, Kirito's only clue to her virtual whereabouts is a mysterious screenshot of Asuna as a fairy trapped in a giant birdcage. His conclusion: She must be trapped within the new, high-powered VRMMORPG, ALfheim Online. Now Kirito must plunge into the world of ALO, where players are fairies who fly gracefully through the air

The boss of the fifth floor of Sword Art Online will drop the Flag of Valor, a dangerously powerful item set to tip the delicate balance between the guilds! Hoping to preserve parity between the two mightiest guilds, Kirito organizes an impromptu raid to be the first to defeat the boss and seize the flag before it falls into the wrong hands...

At long last, Kirito and Asuna have reunited with Kizmel the dark elf. But the happy reunion doesn't last for long. With remaining keys to collect, the appearance of AI that seem a little too lifelike, and a "secret quest" to deal with, Kirito and Asuna will have their hands full as they attempt to clear the sixth floor in one piece!

It's the fifth squad jam and Llen's valued at one hundred million credits. Thrown out into the fog, she's persisted in looking for other participants and finally managed to team up with someone. However, one hour after the start, the outside field starts to crumble until all that's left is a three-kilometer castle. Llen and friends just barely escape the crumble but Pitohui (?) dies from Shirley's(?) exploding ball. The end is nearing, but there's a newly added special rule.??

The moment Kirito, Asuno, and Alice were dragged into the mysterious VRMMO "Unital Ring," Shinon was also thrust into the online world. After numerous setbacks, she finds herself without friends or equipment, and only a few "Thirst Points" left to her name. Backed against a wall, she'll need to defeat a terrifying boss monster to survive. Meanwhile, Kirito's group splits in order to both search for Shinon and defend their home, unaware that a mysterious assailant lies in wait...

After getting separated, Kirito and Eugeo have continued their struggle to reach the 100th floor of Central Cathedral--Eugeo in hopes of restoring Alice to her true self, and Kirito for the sake of the Underworld. But on the 99th floor, Kirito must first face a heartrendingly familiar Integrity Knight...

The Taboo Index and the Law of Power have both been breached by a single murder. The shadowy culprit's intentions are clear as day: the human realm and the dark territory must go to war again. With the help of Iskahn, commander of the Dark Army, Kirito seeks to bring the criminal to justice. But as they conduct an investigation with Asuna's help, disaster strikes again! Ronie and Tiese have been poisoned!

Prepare for a full dive!Even in the future, all the advances and innovation in the world can't change the dynamics of the school playground. And for Haruyuki Arita, a fat kid in junior high, that means he's destined to always be at the bottom of the food chain, prime pickings for the school bullies. But when he is approached by Kuroyukihime, a beautiful and aloof upperclassman, Haruyuki's life is turned on its head as he dives into Brain Burst, a mysterious computer program, and the Accelerated World with her help. It's in the Accel World that Haruyuki casts off his depressing reality and takes hold of the chance to become a Burst Linker, a knight to protect his princess!

The Deity of Demise, Tezcatlipoca, brings chaos to the Accelerated World and shocks Haruyuki into withdrawing from Nega Nebulous. After leaving Kuroyukihime and conceding to the White King, Haruyuki visits Eternal Girls' Academy, where seven powerful enemies and a special trial await him. Could this spell a turning point for Haruyuki and Kurohime, now that they're no longer connected by the Black Legion?
