A place that protects people and creatures lost in other worlds and sends them back to their original homes.
About
Isekai Management Bureau
There is more than just one world.
A world where humans live. A world where beastmen live. A world where magic exists. Worlds under the sea, in the sky, or where night lasts forever—.
Countless worlds exist, each independent of the others.
However, when the boundaries of the worlds waver, individuals sometimes wander into worlds where they were never meant to be.
An organization that protects these lost souls and injured beings, sends them back to their original world and time, and maintains the balance of the worlds.
That is—the "Isekai Management Bureau."
The Isekai Management Bureau is a special place existing at the center of all worlds. It is a place that only those who have become lost between worlds can reach.
They protect the lost, manage the gates and doors connecting worlds, treat those injured in other worlds, support those who have lost their memories, and protect creatures.
This existence is conveyed to all worlds.
In one world, as a novel. In another, as a picture book. And in yet another, as a legend or a picture-story show—.
Only those who hold that book can know of the place called the Isekai Management Bureau.
And today, once again, someone's fate crosses worlds and leads to this place.
This is not a story of those who travel the worlds, but of "those who protect the worlds themselves." _
