🕳️ Zero Era
(The world Kafka was born in — our own)This is the original, real-world timeline — modern-day Earth.Kirishima Himitsu was born here. She lived an ordinary life... until her death and rebirth as a transmigrator.
«The end of a life. The beginning of something far greater.»
🌍 Human History (in this universe)
🔥 Prehistoric Era
Stone tools. Tribal societies. Fire and fear of the dark.
— Not directly explored in the story, but foundational.
🏺 Ancient Civilizations
The birth of writing, myth, and gods.
Mesopotamia, Egypt, India, China.
— Not featured yet, but potential for relics, ruins, or ancestral lore.
⚔️ Medieval Era
[Where the main story begins]
Knights, feudal lords, witch hunts, secret cults.
Kafka's journey starts here, after her transmigration.
— Magic and madness still live in the shadow of castles.
🖋️ Early Modern Era
Renaissance, scientific awakening, the clash between reason and faith.
A transitional age where logic begins to challenge myth.
⚙️ Industrial Age
Steam, factories, revolutions.
A world of machines, emerging technology, and magical-industrial hybrids.
💻 The Modern Epoch (20th–21st century), simply known as the Pre-EpochWars, the internet, space, globalization.Humanity rises — and collapses.
💥 The End of Modern CivilizationA global catastrophe — or a reset of the world.The modern epoch collapses, and the First Epoch begins:The Age of Chaos.History is wiped clean. The supernatural flourishes.
🗂️ World Classifications
Kafka in the modern era will begin a journey through various types of worlds.
Here's how they are classified:
🌀 Alternate Worlds
Familiar worlds — but altered.
The same base setting may branch into different paths, genres, or fates.
Example:
High School DxD ≠ Highschool of the Dead and others
(Both are "modern era," but conceptually incompatible — so they exist as parallel universes)
💾 Virtual Worlds
Digitally coded or artificially constructed realms.
Hacked, simulated, or controlled environments.
Example: Sword Art Online, Log Horizon and others
In the modern world, people can create virtual worlds, which is perfect for Silver Wolf, who practically lives in the rankings.
Oh, come on! Sometimes Kafka also has the right to unwind a bit.
🗝️ Other Worlds
Completely separate realities with their own laws.
Kafka has no default access — she needs special conditions, rituals, or interventions to enter.
Example: Arifureta, Danmachi, One Piece and others
Travel here is restricted, rare, and often dangerous.
🧬 Kafka's Hidden Skill
At a certain point, Kafka gains a unique power:
"Character Theft" — the ability to steal characters from other worlds or stories.
— Details are secret for now.
— Just know: this power has consequences.
🔮 Future Interludes
Occasionally, chapters will include interludes from the future —
brief glimpses of what's coming, to help guide readers through the growing complexity of the story.
✍️ Author's Note
The mystery unfolds slowly.
But everything has a reason.
And every world has its price.
In general, the epochs are intertwined with elements from the works I've watched: manga, anime, novels, films, series, games, etc.
I hope I've more or less explained how long I envision the fanfic to be. Which means a lot of experiments~
I think the only thing left to add are the supplementary chapters: the members of the harem, a chronological list of works, and character descriptions from the prologue (because I don't like setting up a Chekhov's gun and never firing it).
