Kareinaru Akujo ni Naritai wa! Aisare Tensei Shoujo wa, Tanoshii Nidome no Jinsei wo Okurimasu

Mitia Lumiol is set to be another selfish jerk of a noble, one among many who elevate only those with pure bloodlines and great magic. Then, suddenly, she remembers her past life—a lonely, stifled one where her only solace was books and the characters who broke ground where the corrupt stood. Resolving to become just like her favorite villainess, Mitia targets the nobility who rule the land of Elmia with an iron fist. She'll meet kindness with mercy and meet cruelty with ruthlessness. And she isn't going to let anything get in her way—not nobles, not rioters, and certainly not the fact that she can only perform “worthless” household magic. Mitia will show them all what true evil is. And who knows? A cool, elegant villainess might be just what Elmia needs. (Source: J-Novel Club)
