Konno Aiko (紺野 藍子, Konno Aiko?) was the founder and leader of the «Sleeping Knights» guild, a group of terminally ill patients who played VRMMO games, and the elder twin sister of Konno Yuuki. Because of the onset of the Acquired Immune Deficiency Syndrome, she was hospitalised at the Yokohoma General Hospital and registered for a virtual reality (VR) hospice named Serene Garden for palliative care. Due to Merida's influence, Aiko started playing actual virtual reality games, such as Asuka Empire, where she chose to be a spell user and later advanced to being a miko. Her in-game name was Ran (ラン, Ran?).
