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.

Akari Ayame lived 99 lives. 99 lives as the same person, life events and the same fate. Her death at the hands of her love rival and unrequited love. No matter how many different paths she took, in the end, her death was the same. 99 reincarnations. 99 trials to seek her happy ending. 99 tribulations of sorrow, anger and regret. 99 heartbreaks. 99 deaths. In the end Akari was tired of trying. She thought that the reason why she kept reincarnating was to find her happy ending with the man she loved. But with 99 fails, she was tired of the same fate. This time, her 100th time, she would be the matchmaker for her love rival and unrequited love. She will no longer block their love and try to live her life without sorrow, anger, regrets or heartbreak. With the fickle Gods of Fate, how would Akari know that it would only take 100 tries for her to find her happy ending.

Falling into the fiery hell she created must've been the perfect way for her to die. The other woman would then become the heroine that saved the town's people from the mad queen that burnt half of the population down and the duke would become the hero that protected the heroine. They would then be wed and have little children. They would live happily in the new world that they would create after vanquishing the evil queen. They would then lead the people unto a prosperous era of peace. Just... Where?... Where did I go wrong? When I am reborn, will you please give me a simple life?
