Unique Villainess

A perspective of how one could become a villainess! A twist from the typical villainess sister and hero sister

She is technically a villainess but it’s not a main part of the story,
She has a very unique personality and how she power through with magical engineering lol

Female lead is super strong!! The story is pretty different it’s an isekai but the mc is from like the tower system type of stories and she is transmigrated to a villainess
