Summary
Kirito returns from «Sword Art Online», only to find that Asuna (along with 300 people) is still asleep, and is witnessed in another game, called «ALfheim Online».

Stage.001
Two years ago the next generation VRMMO, Sword Art Online (SAO) was launched. On its launch day its creator, Kayaba Akihiko trapped 10,000 players inside the game and claimed that if the player died in the game, they would die in the real world.

Among those trapped was Kirito, who found Kayaba's disguise as a comrade in arms and fought with him on the 75th Floor of Aincrad, defeated him and cleared the game.

Two months after finally logging out of SAO, Kirigaya Kazuto decides to have a kendo match with his sister, Kirigaya Suguha, he doesn't wear protection, but is able to keep up with her. After the practice, he tells her that he might take up kendo again, if she teaches him. She considers telling him a secret, but at the last moment she decides not to. As Kazuto leaves for the hospital, his sister remembers how she discovered that they were cousins rather that siblings while he was trapped in SAO.

In the hospital, Kazuto thinks about his beloved, Yuuki Asuna, who is still trapped in the SAO servers with another three hundred players. In Asuna's room he encounters her father, Yuuki Shouzou, and meets her fiance, Sugou Nobuyuki. After Shouzou leaves, Sugou confesses that Asuna hates him, but he can do as he pleases because he has the right due to his department maintaining the server that keeps Asuna alive. Kazuto wishes to pierce him with a sword when he announces that the ceremony will be held a month later and asks him not to approach Asuna or her family.

Back at home Kazuto is depressed due to his inability to do anything to help Asuna. At that moment, Suguha enters his room and cheers him up before both of them fall asleep on his bed. Kazuto wakes Suguha the next morning and she runs away, then he notices a mail from Agil (Andrew Gilbert Mills), a friend from SAO with a picture of an avatar that resembles Asuna.

At Andrew's restaurant, he tells Kazuto about a game called ALfheim Online and its basics, before explaining that the picture was taken from a place in the game. Kazuto notices that RECTO is the company that designed the game and decides to investigate, in order to find out whether Asuna really is trapped within the game.

At home, Suguha is ashamed and in pain because she likes Kazuto, but he cherishes Asuna instead. Kazuto enters the game and creates his character. Two characters are preparing to fly again, while Kazuto, in his avatar, Kirito, finds himself in a forest instead of the starting city of his race.

Stage.002
After logging in, Kirito looks for the Log Out button. Relieved after finding that it exists, he checks his stats and finds out that they're the same as his avatar's from SAO. He then looks in his items and finds an item called "MHCP001", which he takes out and activates. The item transforms into Yui, an AI that he took as his daughter in SAO. She tells him that they are in a copy of the SAO's server, thus, his stats data was overwritten, but as long as a human GM doesn't checks it, he'll be fine.

Yui transforms into a Navigation Pixie, Kirito tells her that Asuna may be in the game and Yui interrupts by notifying about the presence of other players, three chasing another one. Kirito intervenes and beats two players at once while the other decides to leave. Kirito talks to the female player who was being chased and Yui pops out, so Kirito has to invent excuses.

The player presents herself as Leafa and takes Kirito to Sylvain, where she explains the game basics and talks about the World Tree. Kirito stands and decides to go to the World Tree while Leafa decides to accompany him. They decide to meet up at a tavern the next day and Log Out for the night. When Leafa logs out, in the real world she's revealed to be Suguha, who is trying to decide whether tell Kazuto about her playing ALO.
