[Fgo Anke] Can the Rational 13 Dementia Master Save Humanity?

An Kewen, Dice Niang's choices are all meaningful, I will try my best to make them happy (yuanmu) Things to know before reading: 1. Authors who want to join the pink group, please don't complain about me 2. Engage in Jiwen, and some of the followers are male, such as Arthur, Nero, etc. 3. The characters are OOC, the plot is crazy, and there are many private settings. The author likes to skip when playing games. I am currently revisiting the main plot. Purpose: Save the world
