A Witch Lives in the Emperor’s Bedroom

All humans are merely actors on the stage called the world.

Therefore, I act too, even if that means acting as a witch.

Once every hundred years, the Latus Empire gives birth to a so-called ‘witch.’ Witches possess transcendent magical power and an overwhelming desire for slaughter, and are said not to stop until they have killed a thousand people. So when the witch’s day comes, all heavily pregnant women are taken away and watched, and the witch is killed immediately after being born.

The returned witch’s day.

I don’t mind dying. If only I can take revenge on those who abused me.

Isabella, who was adopted into the White family as a child and has been abused ever since, decides to act meek and foolish while plotting revenge, until the day she awakens as a witch.

Become the duchess.

Zenos Ferdian, the grand duke who hides his true intentions and acts as the emperor’s loyal dog, is in the middle of arranging a marriage with a wealthy daughter of the White family when he sees Isabella awaken as a witch. He tells Isabella to become his duchess and help him ascend to the throne, and Isabella joins hands with Zenos, thinking she may be able to take revenge on the White family.
