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.

Do you believe in the Imperial Truth? I admire the first person to make a deal with the Four Gods; they might even end up paralyzed on the toilet. Yellow-skinned man, when I build the Warp Pump, I'll definitely make you awaken. Those who awaken will eventually step down from the Golden Throne. Finally, let me say this: technology is accelerating! 'Solar Tomahawk', 'Thor Mech', 'Arc Generator', 'Hyperspace Rail', 'Warp Drive', 'Cybercles', 'Aether Phase Drive', 'The Reincarnation of the Om Messiah'. That's all—'Made in Stellaris!' Serious version: Leon, who traveled to the remote Warhammer of the M32 era, became a soulless being. With the knowledge he had gained from many other science fiction works before his travels, he transformed himself into a priest of the Mechanicum. While replicating the technologies of various other worlds in the Warhammer universe, he began to spread the light of reason brought by the truth and technology of the Empire in this cesspool of a universe. He punched the greenskins, kicked the Chaos, gathered the traitor legions, and reshaped the future of mankind... In theory, this is how it should have been. Looking at the closed gate of the Terra Palace in front of him, Leon said with tears in his eyes: "Open the door! I really am here to save the Emperor from the toilet!"

[Arknights x Project Moon]

After transmigrating into the world of Arknights, Lin Yi finds himself turned into a mobile city.

But when he spots Sweepers patrolling the alleys and streets, he realizes something is very wrong.

Buhao! This is Project Moon "The City"! You're telling me this thing counts as a mobile city?!

So let me get this straight—you're asking a city with zero Singularity tech to take on an entire district by itself?

Luckily, Lin Yi still has a well. With this single well, he can draw forth tools, artifacts—even identities—from across the multiverse. And so, a brand-new path begins to unfold.

“Hey, friend—interested in becoming a Fixer? First-time sign-up gets a free identity, no strings attached!”

...

Years later, Lin Yi stands at the heart of his bustling, human-centered city—gazing at the many people before him, each overlaid with personas drawn from countless realities—and recalls the afternoon he first became a mobile city.

Talulah · Fixer Identity : "Speak. I will protect all that belongs to Ursus."

Skadi · Ishmael Identity : "My mistake? I’d say it’s all thanks to me!"

Ch’en Hui-chieh · Dayan Emperor Identity : "I came to this city and saw vitality—life in full bloom, thriving in every corner."

W · Red Mist Identity : "Tell me—what does 'power' really mean?"

Lin Yi : “So... who’s next to tell their story?”
