Konno Yuuki

Konno Yuuki (紺野木綿季) was one of the players of «ALfheim Online». She leads the guild «Sleeping Knights», a group of terminally ill patients who play using the FullDive Technology MediCuboid. She is also known as Zekken, or Absolute Sword. She won 67 consecutive duels on the street. She beat Kirito in a duel, although Kirito was only using one sword at that time. 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 while logged on ALO in Asuna's arms, surrounded by her friends and many other players.

Background
Prior to becoming known as Yuuki of ALO, Konno Yuuki was a child suffering from "Acquired Immunity Difficiency Syndrome" (AIDS). 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 (Human Immunodeficiency Virus) 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 parents and teachers of her old school.

Chronology
She is first introduced as Zekken, a street swordsman offering an 11-hit Original Sword Skill, to whoever beats her. After fighting a good 60 some battles, Asuna challenges her. Althogh Asuna loses, Yuuki is impressed and thus asks Asuna for her help in defeating the floors' boss. After two tries, the Sleeping Kngihts beat the floor. As time progresses, Asuna gets to know Yuuki in the real world. She even 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.
