Zero no Tsukaima - Volume 2 Chapter 9

When our protagonist becomes the game character Jun Karentia, she thinks she has it made. She may be just a lowly support mage, but with her knowledge of the game, she knows she can finagle her way to the good ending following around the main character, Fabian. The problem? This game doesn’t end after one playthrough. Jun is prepared to guide Fabian through the second playthrough to the true ending when… Fabian abandons her. Now the Grand Duke Mayer Knox—captain of the Dark Knights and the secret final boss—is determined to have her join his party. Can Jun turn the final boss into the main character? Why is Mayer Knox so intent on having her in his party? And when will these rumors about being his lover stop?!

I possessed a third-rate villain who died in every route of my favorite game.

But I want to live.

When Hazel finally turned adult, her father did not think twice before selling her to the emperor of a mysterious land. The man was famous for killing all her brides in less than a week but Hazel had a deep will to survive.

From behaving crazy to a villainess, she would do anything that keeps her safe until she find a way to escape. But why is that the Evil Vampire Lord behaves so differently than the rumors she had heard. Did she even want to run away now?

With the revival of spiritual energy and the breakdown of the order of species, it is a difficult test whether human beings can still stand at the top of the biological chain.

(There is already an old book, The Strongest Descends in the City, you can read it.)
