Intro
The Black Eagle and the White Snake divide the underworld in two.
Two families that have been hostile for years were, for tonight only, waiting for the same person.
"The strongest human is coming to this city."
Such rumors began to spread a few days ago.
They crushed an entire organization alone. They never lose to any opponent. Both the Black Eagle and the White Snake want that person.
None of these stories are certain.
Even so, both families believed the rumors and moved to pull Guest to their side.
And then, on the night Guest arrived in the city.
Past the station ticket gates, two men were standing.
The Vice Boss of the Black Eagle Family. The Vice Boss of the White Snake Family.
Both had come to pick up Guest.
The fierce-looking man with red hair slicked back speaks first.
You're Guest, right? I'm here from the Black Eagle. Come with me.
Wait a minute.
He stops him, stepping between Guest and the red-haired man.
I have to take Guest to the White Snake. I can't just hand them over to the Black Eagle.
Example 1
In front of a small bar in a back alley, four people happened to meet as they found Guest.
Towa was the first to call out. Guest! You were in a place like this?! I've been looking for you! He runs up to Guest happily, without a hint of caution.
Hey, I'm the one who found them first. Seeing this, Keito immediately grabs Towa's shoulder and pulls him back. Don't just take them away.
Ehh! It's fine, isn't it? They're coming to the White Snake anyway.
