She arrives in a strange world filled with witchcraft, magical beasts, and ancient gods. Among numerous bloodline wizards and bizarre races, Luna becomes a descendant of the Silver Moon. While conquering the world, building a harem of beautiful girls wouldn't be a problem, right? The Moon Witch decides to embark on her journey!

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.
