The Queen of the Lake
One day at the end of the year, Kirigaya Suguha showed her cousin, Kirigaya Kazuto, a news article about the legendary item, the «Holy Sword Excaliber», being discovered in ALfheim Online. Without delay, he called Asuna, Klein, Lisbeth, Silica and Sinon to challenge the dungeon in the sky of Jötunheimr, where Excaliber was . After preparing their items at Lisbeth's arms shop and purchasing potions for the adventure, the group entered Jötunheimr via a secret passageway in Alne. At the end of the tunnel, they reached the top of Jötunheimr and Leafa called Tonkii, a flying evil-god-class monster that they had befriended several months ago. The group climbed on Tonkii's back and asked it to ferry them to the ice dungeon. However, along the way, Tonkii suddenly dived and stopped at an altitude where they could see the ground. There they saw that players were cooperating with the humanoid evil-god-class monsters to massacre Tonkii's kin, the beast evil-god-class monsters. As they were watching the scene, a giant NPC, the «Queen of the Lake» Urðr, appeared behind them. The NPC explained that the massacre was ordered by the king of the giants, Þrym, who once threw the Holy Sword Excaliber into Urðr's Spring and caused the world of Jötunheimr to turn into an icy wasteland. She then explained that if all of Tonkii's kin were slaughtered, she would lose her power and this would allow Þrym to invade the land of the fairies, Alfheim. To prevent this, Urðr requested the fairies to retrieve the Holy Sword Excaliber from the bottom of the ice dungeon, called Þrymheimr.

Sword Art Online II
One year after the SAO incident, Kirito is approached by Seijiro Kikuoka from Japan's Ministry of Internal Affairs and Communications Department "VR Division" with a rather peculiar request.
That was an investigation on the "Death Gun" incident that occurred in the gun and steel filled VRMMO called Gun Gale Online (GGO). "Players who are shot by a mysterious avatar with a jet black gun lose their lives even in the real world..." Failing to turn down Kikuoka's bizarre request, Kirito logs in to GGO even though he is not completely convinced that the virtual world could physically affect the real world.
Kirito wanders in an unfamiliar world in order to gain any clues about the "Death Gun." Then, a female sniper named Sinon who owns a gigantic "Hecate II" rifle extends Kirito a helping hand. With Sinon's help, Kirito decides to enter the "Bullet of Bullets," a large tournament to choose the most powerful gunner within the realm of GGO, in hopes to become the target of the "Death Gun" and make direct contact with the mysterious avatar.
