Introduction
While Asuna, Leafa, Silica and Lisbeth were doing their homework in Kirito and Asuna's Log House on the 22nd Floor of New Aincrad, Lisbeth informed Asuna of a player known as Absolute Sword who was challenging players on the 24th Floor, while offering an 11-hit Original Sword Skill as a reward. Asuna was told that the mysterious player had actually converted from a different game and that over thirty players who had attempted to challenge the player, including Leafa and even Kirito, were defeated. Hearing that Kirito had said something to the player before being defeated and not sharing what he had said with the others and thinking that the mysterious player had come for a reason, Asuna decided to challenge the player as well. To her surprise, the player was actually a girl, named Yuuki. Asuna battled intensely and even managed to force Yuuki to use her powerful Original Sword Skill, but was still defeated. However, Yuuki then suddenly asked her to come with her and Asuna was brought to an bar in Ronbaru, the main city of the 27th Floor, where she was introduced to Yuuki's guild, called Sleeping Knights, which consisted of six players who had all converted from other games. The guild told Asuna that they were looking for a player who was as strong as Yuuki to fill in the last remaining slot in their party and help them defeat the next Floor Boss to have their names etched on the Monument of Swordsmen, in order to leave a memory of their existence in the world, which they found to be the most beautiful of the ones they had visited, before the guild disbanded.
