Konno Yuuki

Konno Yuuki (紺野木綿季) was a player of «ALfheim Online». She was the 2nd leader of the guild: «Sleeping Knights», a group of terminally ill patients who played as a form of mental treatment and rehabilitation. She is also known as Zekken, or Absolute Sword. She won 67 consecutive duels on the street, including Kirito, although Kirito was only using one sword at that time. She created an 11-hit Original Sword Skill, an incredible feat according to the novel. Kirito stated that her reaction speed was even higher than his and she was much more immersed into virtual reality than he was. She spent her last moments of life while logged on ALO in Asuna's arms, surrounded by her friends and more than a thousand other players.

Background
Prior to becoming known as Yuuki of ALO, Konno Yuuki was a child suffering from "Acquired Immunity Deficiency Syndrome" (AIDS) since birth; her parents, as well as her sister Aiko, were infected too. Despite this, she had always believed that one day she would be healed and continued to strive towards her goals. However, during the course of 4th grade, a group of students found out that Yuuki was a carrier of HIV and began spreading rumors about Yuuki. Because of this, Yuuki was forced to transfer to another school. After transferring to a new school, Yuuki's condition gradually became worse and the reason suspected by her doctor was from the rejection caused by the parents and teachers of her old school. Her parents died two years ago, and her sister the year before the events of Mother's Rosario.

Mother's Rosario
Yuuki is first introduced as Zekken, a street swordsman offering an 11-hit Original Sword Skill to the person who defeats her. After fighting through a sixty-seven battle win streak, she is challenged by Asuna. Although Asuna loses, Yuuki is impressed and thus asks Asuna on behalf of everyone in her guild for her help in defeating the floors' boss. Asuna readily agrees. The first attempt at defeating the floor's boss was unsuccessful, but after backup support on the second try, the Sleeping Knights beat the floor. As time progresses, Asuna gets to know Yuuki in the real world. She goes to great lengths to ensure that Yuuki can enjoy the "real" world again by asking Kirito to help her with the technology that he had been developing in school. Yuuki, through Kirito's camera, was able to enjoy the school at the SAO victim's school. Unfortunately, her condition gradually worsened, but as she slowly died in Asuna's arms, Kirito and many players of ALfheim Online surround her, and she passes away in happiness.
