- Description from novelbuddy

To save the hopeless Dark Fantasy World, I held back my tears and destroyed the world, then killed the Demon King and returned.

Now, I’m trying to save the world using the ‘System’ I gained as the ‘Regressor’s Privilege’… but the Main Heroines have also awakened their memories of the previous timeline.

God damnit.

A classic villainess/heroine tale that puts a new twist on the genre. This Industrial Era fantasy tells the story of Nadia—a secret agent with a dry love life and an unhealthy addiction to visual novels—as she Transmigrates into the body of Vivian Moore, the villainess of the novel, from a family of business CEOs.All the destruction flags were raised, and Vivian was at the end of her rope. Her life was about to take a turn for the worst, but with Nadia behind the wheel, she seized Fate by the hairs of its head and yanked it into a sharp U-turn.No more weakness was allowed! If something wanted to get rid of her, she would stab it to death. If someone wanted to trample over her, she would shoot them into a beehive. And there was no stopping her because she had the strongest weapon a main character can have: the System!
