Mary Saves the World! [Anime Crossover]

What is justice? Justice? Justice is... sleeping around! I'm a Mary Sue, a true-blue Mary Sue, blessed with every cheat skill, melodramatic plot twist, saintly heroine trait, and protagonist halo imaginable. I'm a good Mary Sue. My values are more or less normal, and my sexuality isn't twisted. I may love danmei, but I've never actually tried to turn anyone gay (probably). My goal is to become the finest Sue among all the Marys. That way, I can make one wish: to live this life well, then be reborn in peace without my memories. So I've always been striving for the crown of Mary Sue, upholding the justice of the Mary Sue! Fighting fire with fire, and answering Sue with Sue! This is a crossover fic set in an extremely muddled era, with lots of personal inventions and speculation that won't stand up to scrutiny. So, great lore detectives, please go easy on me. I'm only writing for fun and to make you smile. If you take it seriously, you've already lost. P.S.: Thanks to Beiyin for making the cover!!! I'm so touched, ahhhhh!! TAT! It's the first time anyone has offered to make a cover for a klutz like me, ahhhhh!! Can you believe it! Can you believe it!!!
