A Murder Case in the Area (Aincrad 57th floor, April 2024)
Upon returning to the city Kirito and Asuna witness a murder within the city, an anti-crime prevention area. A man thrown out of a window while impaled by a spear, dies right before their eyes. Both bewildered they try to find a normal cause for the murder, but none appears so they find themselves starting to investigate a murder case. First they interview a witness, a girl, Yolko, who was supposed to meet up with the victim, Caynz. They also retrieve the murder weapon, Guilty Thorn, which they take to Agil to find out more about it. After Asuna and Kirito call it a day, Schmitt from the Divine Dragon Alliance shows up with a group of people from his guild and robs Kirito of Guilty Thorn. The next day, Asuna and Kirito pay Schmitt a visit; he was willing to assist them as long as he was able to talk to Yolko again. Yolko is suddenly murdered during the conversation and Kirito attempts to capture a hooded man on the roof. Schmitt gives Kirito a list of names of the members who were part of the «Golden Apple» guild. Kirito realizes that the real perpetrator was actually the spouse of the dead guild leader of the Golden Apples. He had been after a ring that granted amazing bonus stats that could sell for a lot of gold. Schmitt feels guilty for being an accomplice in the death of the guild leader and decides to visit her grave only to find Yolko and Caynz still alive. Kirito explains that Caynz and Kains were similar names when spoken and that Yolko had lied to both him and Asuna. Three members from the killing guild «Laughing Coffin» show up at the deceased guild leaders' grave and attempt to kill Schmitt, Yolko, and Cayne. Kirito steps in to save the day. Asuna catches Grimlock, the spouse, hiding in the bushes. He admits that he was the mastermind behind the death of his wife; he did not want her personality to change from what it was originally in the real world.

Caliber (ALfheim, December 2025)
The quest to retrieve «Excaliber» from the base of Jötunheimr was revealed to the public. It was not the way Kirito and Suguha saw, but another mission which is to slaughter all beast type evil-gods. Kirito and his party of seven enter the floating castle of the frost giants. They are given a quest by «The Queen of the Lake», Urðr. She tells them of a once beautiful Jötunheimr where the roots of the Yggdrasil touched the floor and the endless void in the center of the land was filled with water of the purest quality. The Frost Giants had used the sword «Excaliber» to cut off the roots of the great tree and turned Jötunheimr into a frozen wasteland. The party enters the upside-down pyramid to clear its four floors and obtain Excaliber. Along the way, at the end of the third floor, they run into Freyja, a captured beauty. During the battle with the final boss, Giant King Þrym, Freyja transforms into the God Thor after retrieving his Mjölnir, the lightning hammer. After defeating Þrym, the group heads into a narrow staircase and finds «Excaliber». After much effort, Kirito pulls the blade out while the fortress begins to collapse. While falling, Tonkii saves the group but to Kirito's dismay, «Excaliber» was lost. Suddenly, Sinon sends a retrieval arrow towards the blade and has Kirito swear that he would think of her every time he uses to sword before giving it to him. They are then met by Urðr and her sisters to receive the reward for completing the request. The group is loaded with treasure and then decide to log out and have a party at Agil's cafe.

First Day (Aincrad 1st floor, November 2022)
As the SAO death game begins, Kirito rushes to the village named Horunka to get a headstart on the quest which will reward him the «Anneal Blade» which is strong enough to last him for the first 3 floors. During his quest, Kirito finds another beta tester like him. Coper, who proposes that they try to complete the quest to obtain a new sword together. After Kirito gets the item needed to complete the quest, Coper purposely activates a trap which releases a horde of monsters. Kirito realizes that Coper was trying to kill him. After a tough fight, he manages to escape but Coper dies; this heavily affects Kirito as he realizes he can die in this game. Kirito returns and completes the quest, in the scene after he remembers his sister Suguha.
