On Earth, in a Japanese hospital, permanently disabled patient Keina Kagami dies when her life support fails in a massive power outage. To her immense surprise, she awakens in the world of Leadale, the setting of the virtual reality role-playing game she had been using to interact with the rest of the world, as her avatar, the high elf mage Cayne. From the proprietors of the inn in which she awakens, she is shocked to learn that 200 years have passed since she last entered the game, and that the White Kingdom of Felstes and Green Kingdom of Gruskeilo - the settings she had played in - have merged into one kingdom about 60 years ago and have since descended into poverty; and from her AI support unit Key, she also learns about what happened to her on Earth. Clueless about what to do, she decides to visit her operation base in the game, the Silver Tower, only to be reminded by the tower's golem guardian that she has several children, whom she adopted through the game's Foster System. On her way back to the inn, she saves a hunter from a monster, and passes out from drinking wine at the subsequent feast.
