A boy who awakens his memories of his past life wakes up to find himself facing a "zombie crisis." Is this some kind of American variety show world, or the world of Hunter x Hunter?

So the first thing to do now is to escape this city.

Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

Question: Beneath the starry sky, there stands a beauty. Her long black hair flows like eternal night, her bright eyes shimmer like the stars, her immense magic makes the world tremble, and her unparalleled beauty compels all beings to bow before her. Who is this beauty?

“That’s right, it’s me, the Queen of Witches, Dorothy!”

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.
