When O'Sullivan Meredith woke up, she remembered her past life. Thanks for asking: she landed in a spectacularly mixed-bag family, and now she's in Mary Geoise, living as the world's greatest piece of trash.
Given how much the Celestial Dragons are hated, she can expect a few decades of wealth and luxury, and then... well, there won't be a then. What kind of happy ending could a vicious villain and class enemy possibly get?
Luckily, she has the Celestial Dragon Survival Simulator.
In her first simulation, she chose to leave Mary Geoise with her fiance, the Donquixote family. After her mother-in-law died of illness and her fiance killed his own father, her frail, pampered body finally gave out under the terrible living conditions and one blow after another. She became the third person in the family to die.
Unwilling to admit defeat, Lady Meredith chose to try again. This time, she set her sights on Borsalino, a new Marine recruit she met by chance at a coffee shop...
Somewhere along the way, the Grand Line grew more and more chaotic. The Navy, the Whitebeard Pirates, the Red-Haired Pirates, and the Revolutionary Army all kept insisting: "You don't understand. She's not like the other Celestial Dragons."
Meredith, finally free of her birth family, heard the rumors and replied, "Well... I suppose I am a little different. After all, I'm the only Celestial Dragon who's staged a rebellion against herself."
"Reputation, morality, love: none of it matters. I just want to live freely and do as I please."
[Please Note]
* The heroine grows over time and is chaotic neutral. The memories of her past life gave her personality a corrective punch, but some of the Celestial Dragons' incurable traits remain...
* Her rebellion isn't about joining the Revolutionary Army. It's about founding a new regime.
* An unconventional simulator, maybe? Includes original worldbuilding.
* A villainess adored by everyone, with multiple romantic routes, including the three Navy admirals, the Donquixote brothers, and Sabo... Her status and personality bring plenty of love and hate, fighting while in love, tragic romance, and even "my nemesis is my wife." The endgame pairing is undecided.
