Rekishi ni Nokoru Akujo ni Naru zo: Akuyaku Reijou ni Naru hodo Ouji no Dekiai wa Kasoku suru you desu!

I've never been able to stand the typical heroine's "goody-two-shoes" routine. Thankfully, all my dreams come true when I'm reincarnated as a villainess! Determined to become a woman no one can criticize, I do my best to train my body, improve my intellect, and hone my magical skills. But for some reason, the harder I try, the more everyone seems to like me! No matter—I'll betray their every expectation and become the greatest villainess the world has ever known!
