@Deoxyribo9 Not to mention WN/LN otome reincarnations haven't been extensively adapted for anime yet unlike their male-targeted counterparts, the JRPG reincarnation/summoning. Unless you count in the upcoming Bakarina/My Next Life as A Villainess as the 1st otome reincarnation anime which debuts this April 2020.
Common Sense: Finally! A "normal" duke's daughter!
103 chapter later....
Traumatized Common Sense: What is "normal"? Why do I exist? *existential crisis*
Also, the family is adorable... except for that one person *shiver*
@Siceraria I must inform you with great regret "Common Sense-chan" have already been murdered a thousand times over even in reality. So much that another few thousand deaths in fictional universes don't feel like a thing.
