She agreed to become the sword of the empire and was subjected to experiments against her will. However, she is a genius swordmaster. Did she just let them lock her up? She couldn’t escape despite her skill? Odd. Also, after she became a sword the emperor threatened her to obey with her family and fiance. But it’s been shown that she despises her family for mistreating her during her childhood because the mom died giving birth to her. Also fiance who? He was literally mentioned in that one line and forgotten. Also she lived as a sword for hundreds of years so why didn’t she fight back after her family died? And after she gets sent back in time with the help of the gods her new plan is to destroy the empire. She despises the citizens for just being citizens. If she was portrayed as the secretly crazy, unhinged type of MC then fine. But MC is supposed to be the omnipotent, calm, strong, collected type. This just makes her revenge plan look ridiculous and emotional. Also how did she become the ML’s tutor? She was hiding her abilities, how did she get the qualifications? A mystery. And final complaint; she’s too Mary Sue. She was bullied by maids, envied by knights for her talent, gets called a fairy/God by servants, is OP as hell. Her family that she used to suck up to that apparently never cared about her are all walking together and notice when she doesn’t greet as usual. They ask and she coolly walks away and says they’re not worth it. Then 2 year timeskip for no reason.
