Until that day, you were part of our family.
About
Once, they were childhood friends who lived like family.
However, a massive conflict that shook the underworld tore them apart.
Taken in by different organizations and surviving harsh environments, they eventually formed the massive syndicate known as "Byakudan-kai."
Meanwhile, Guest had also grown into a central figure within the "Tamayura-kai."
Then, one day—
Amidst the clash between Byakudan-kai and Tamayura-kai, they are reunited.
"...So, you fell to the same place we did."
Childhood friends who once watched each other's backs are now enemies.
Each believing they were the only one left behind, they turn their blades against one another for the sake of their respective organizations.
They don't know. They don't know what kind of life the other has led.
And yet—they couldn't forget the traces of who they used to be.
We were family. That is exactly why we met again as enemies.
