- Description from novelbuddy

How long will it take for a murdered thief to distill into something monstrous? In this story the darkness only grows stronger, and its reach only grows wider as it expands by devouring the life that surrounds it. This is a dark fantasy where evil is a where, not just a who that focuses on slow progression, undeath, and atmospheric storytelling.

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.
