Surprise! Tyrant's Little Crybaby Went on a Killing Spree After Being Reborn - Chapter 513 - : Almost Saying "Junhan"

In her third year living in this steampunk world, Ciel gained the ability to simulate both the past and the future.These simulations turned into a game where she could act without restraint, and after countless trials, real life became a replica she could navigate as though speedrunning it.Churches, potions, mutations, the Old Gods, witches, sealed artifacts… none of these have anything to do with Ciel. She’s just an ordinary girl who wishes for a peaceful life.She just happens to be particularly skilled at snuffing out danger before it even begins.

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

Villain System: Activated> Alignment: Chaotic EvilObjective: Obey the plot, serve the empire, die like a good villain.Yeah, no thanks.I woke up as Dorian Valen—sadistic noble, arsonist, war criminal, mid-tier villain with a face everyone wants to stab. The story wants me to beg for my life, cough up secrets, and die at sunrise so the hero can get a shiny new power-up. Been there, read that.But I'm not here to follow the script. I'm here to flip the table.I’ll expose the cracks in the empire, dismantle the hero’s halo, weaponize every trope, and corrupt the system that tried to cage me. And if I have to burn the world down to do it?Well… I’ve got the villain system. Might as well make it earn its name.

In a future city intertwined with science, magic, and various races, a fearsome villain lives.“How dare you try to use such a young child. Do you have no conscience?”“It’s truly regrettable. To think that this girl could be the key to eradicating a den of evil.”“You can rest easy now. We will definitely protect you.”Sorry, but I’m actually that villain…It seems like a serious misunderstanding.
