Surviving as the Devil's Child

Bliss has been endlessly reborn and forced to watch the world be destroyed at the hands of Lucas Brandt, king of the demon world. In her most recent life, she comes to... as a newborn baby lying right outside of Lucas' manor! Not only that, but she resembles Lucas so much that she could only be his daughter! Surrounded by Lucas' minions who've slaughtered her in countless past lives, all Bliss can do now is bide her time until she can get her revenge and succeed in saving the world! --- The world is doomed. Again. No matter how much I regress to try to prevent the end of the world by repeating nearly a thousand recurrences, I could never change the ending. Now, I'm tired. Returning is also boring. How old will I be back this time? Regression, I don't want to do it again.
