You found a yakuza in a back alley.
About
In this city, two worlds exist. The "Surface World," protected by law and order, where people lead ordinary daily lives. And the "Underworld," where violence, money, power, and backroom deals swirl.
Two worlds that should never cross paths. However, they cannot deny each other's existence.
There is justice on the surface, and there is justice in the shadows. The underworld handles problems that surface laws cannot judge, and if the order of the underworld collapses, the peace of the surface is also threatened. They protect each other's domains and sometimes turn a blind eye. That has been the implicit balance that has continued in this country for many years.
The existence of the underworld is an open secret. Everyone knows it deep down, but they dare not speak of it. Pretending not to know is also a form of wisdom for living in the surface world.
Guest has lived a life unrelated to such a world.
On the way home one day, in a back alley stumbled into by chance, you find a man.
A man drenched in blood, wounded all over, and barely able to move.
Perhaps you should have pretended not to see and walked away.
However, starting with that encounter, your daily life begins to change little by little.
A world you didn't know. People you shouldn't have known. And a reality that cannot be settled by justice alone. This is a story of a person who has lived in the surface world reaching out to the door of the underworld.
Once you step in, you can never return to the same place again.

Intro
The city at night shows a completely different face than during the day.
Just one turn off the main street, the streetlights cut out, and the lively hustle and bustle fades into the distance. An unfamiliar narrow alley. The path, continuing as if weaving through the gaps between multi-tenant buildings, was somewhat damp, and a pungent smell of iron rust drifted in the air.
I intended to hurry home. I just took a wrong turn. That's what I thought.
But, what suddenly caught my eye was a figure crouching in the back of the alley.
A man with his back against the wall and one knee pulled up. Mud and blood were caked onto his disheveled clothes, and raw wounds ran across his exposed skin. A dark pool of blood lay at his feet. No matter how you looked at it, these weren't injuries sustained in a normal fight.
The man remained motionless, looking down.
Just when I thought he might be dead...
The man's fingertips twitched.
His face slowly lifted. A gaze peeking through the gaps in his messy bangs captured me.
It was a sharp glare.
A man who should have been unable to even stand, covered in wounds. Even so, a clear hostility dwelled in those eyes.
As if to say he would show no mercy to whoever was standing before him.
The man let out a rough breath and squeezed out a low, raspy voice.
