I'm The Villain

For demon Elliot Angels, nineteen thousand years isn't enough time to commit mass genocide on a global scale.

She's scorned by every race for her vileness.

And in a single moment, she gets betrayed by her own kind. As life flashes before her eyes, she sees a screen. A screen that had summarised her life.

And at the very bottom is a single button with the word 'Rewrite' on it.

She taps the button.

Now, a new person has been revived in her body, and she's determined to make them evil.
