Konno Yuuki, known as Yuuki in «Serene Garden», «Asuka Empire», «Insect Site», and «ALfheim Online» (ALO), was the deuteragonist of the Mother's Rosario side story, and the protagonist of the Sisters' Prayer side story in the Sword Art Online series. She was the younger sister of Konno Aiko and one of the three founders and the 2nd leader of the «Sleeping Knights» guild, a group of terminally ill patients who met in Serene Garden, a virtual hospice for the terminally ill, and played various virtual reality games as a form of palliative care. After two years of visiting a variety of virtual worlds, Yuuki and her guild eventually arrived at ALfheim Online, where she became known as Absolute Sword due to winning sixty-seven consecutive duels on the street, including one against Kirito. She was also known for creating the eleven-hit Original Sword Skill named Mother's Rosario in the game. She spent her last moments of life while logged on to ALO in Asuna's arms, surrounded by her friends and more than a thousand other players. Yuuki had short, black-brown hair and, in the final moments of her life, she had extremely pale skin, which made her look very sick. In ALfheim Online, Yuuki's avatar was a slim Imp with milky white with a hint of purple skin, lustrous and gorgeous, long, purplish-black hair, and red eyes. She wore obsidian chest armour, a bluebottle violet tunic and a windswept skirt of the same colour beneath the armour. A thin, black sheath hung on her waist. Yuuki was the kind of person willing to live life to the fullest even in her critical condition, when she died peacefully in happiness. She believed some things must be done in forceful means for the other party to understand.
