What would happen if an unnamed person from 2020 got reincarnated in Youjo Senki as the sister of Tanya Degurechaff. A story about a girl who loves to play strategy games, watch anime, read manga/manhwa and learn things that interest her to a deep understanding of the topic in her previous life trying to survive in a world on the brink of WW1. This is the story of Olivia Degurechaff. The Empire will be advanced in technology because of Olivia and Tanya (Just a heads up) Please be reminded that I don't own Youjo Senki or the images or videos I may use in the future. This fanfic will be mostly based on the manga but with a bit of twist for my story. Glory To The Empire!
