indigo's Manga

mc dies and gets reincarnated ito the body of a noble who's v insecure and hates her sister and who's also dies five years later so she tries to be kind and yeah

mc gets forcibly transformed into a sword and gets used to kill ppl by emperors right and left for 400 years then she gets reincarnated, so she sets out to secure a future for herself and destroy the empire that broke her by teaching a genuis prince to be a tyrant. prince is pretty gullible but i guess that's what happens when ur young and that crazy bitch telling u to destroy ur own empire is the only person left in the world that gives u attention and affection

mc gets isekai'd into a book (? i forgot lol) and becomes her favourite character however, said character has an incurable disease and is literally dying so fun

mc gets reincarnated into a Cinderella-like world but except from the characters, nothing is following the plot of Cinderella lol. also their eyeliners are cool
