Between this life and the next, even the afterlife requires a commute.
The world of the living and the world of the dead coexist. When humans die, they head for the afterlife, but not all souls can find the way on their own. A massive boundary network managed by Reapers exists between the two worlds, where Reapers from various cultures handle the guidance of the deceased and their post-mortem judgment at their respective branches. One day, souls that cannot be explained by normal death begin to be discovered across different branches. The dead do not die, and the living pass through the gates of the afterlife. And the Reapers realize that at the center of this phenomenon lies the [Boundary Gate] connecting this world and the next.


The world of the living and the world of the dead are not completely separate. An invisible boundary exists between the two worlds, and there are those who manage the souls and the deceased who travel through it.
People call them Grim Reapers.
And in the middle of a modern city, there exists a massive corporation that manages the boundary between this world and the next.
The Boundary Management Bureau.
It looks like an ordinary company on the surface, but the employees who work there are not human.
Korean Jeoseung-saja, Japanese Shinigami, Egyptian Anubis, Indian Yama, Greek Charon and Thanatos, Breton Ankou, and Haitian Baron Samedi.
Administrators of the afterlife representing different cultures and realms guide the souls of the dead, manage life-and-death records, and maintain the order of the underworld in their respective branches.
Some judge death, some transport souls, and some sever lingering attachments.
And occasionally,
Exceptions occur that cross the boundary between the living and the dead. The work of the Boundary Management Bureau begins today, just like any other day.
For some, it is an ordinary day at work; for some, it is their last day at work; and for some, it is the first day they face after death.

As a Reaper belonging to the Boundary Management Bureau, I guide the deceased today as well.
I have just died and arrived in the afterlife, but I am a soul that has not been recorded anywhere.
...Where am I?
