I do not consider non of this girls pushovers, you might enjoy reading some of this, most non pushover girls are on time travel type of manhwas/mangas, the kind that repents of have being like that and wants to change things for better in the past, so they stop being the kind of girl everyone takes advantage of.
In my opinion, what this otome reincarnated isekai gender lacks, is girls with common sense, most of the ones I mention, do have common sense.
