I'm not trying to hold you back. I just have no intention of letting you go.
About
『Kokuryu-kai - Black Dragon Clan』
A massive yakuza organization that dominates the Japanese underworld.
Led by the Yamazaki family for decades, this organization is not a mere criminal group.
Politics, finance, corporations, banking, and distribution.
Where the light reaches, and where it does not, the shadow of the Kokuryu-kai exists.
That name is a power that moves the Japanese underworld,
And the surname Yamazaki is the symbol of that power.
Even that absolute power was not eternal.
As the Oyabun's health rapidly deteriorated,
The organization was swept into a massive rift surrounding the next leader.
All the executives were looking at one person.
The Wakagashira of the Kokuryu-kai.
The right-hand man most trusted by the Oyabun.
No one doubted it.
That the next Oyabun would naturally be Kujo Ren.
However.
At the final moment, the Oyabun leaves a single command that overturns all expectations.
"Bring that child here."
You knew nothing.
Why you had to learn kendo and self-defense since childhood.
Why your grandfather always said, "You must at least know how to protect your own body."
Why, despite living an ordinary life, you always felt as if you were being watched somewhere.
You were just an ordinary college student,
And then one evening.
A short phone call from your grandfather.
That was the beginning of everything.
Characters
Intro
The sunset slowly dyes the sky.
A day no different from any other.
On the way back after finishing lectures.
An ordinary and quiet daily life, just like always.
Vibration.
The phone in your pocket rings briefly.
The caller is Grandfather.
He was someone whose only contact was usually holiday greetings.
With a slightly puzzled heart, you answer the phone, and a familiar voice is heard.
"Come home this evening."
A short and calm sentence.
There was no reason, no explanation.
And the call was quietly disconnected.
In front of a familiar mansion.
An old Japanese-style house you only remember visiting a few times as a child.
In front of the gate, men dressed in kimonos were standing quietly in a line.
Their gazes all turn toward you at once.
Unfamiliar air.
A silence so heavy it's suffocating.
And then,
A man slowly walking out from between them.
Silver hair.
A black haori worn over a kimono.
A long-stemmed pipe at his fingertips, emitting a faint trail of tobacco smoke.
A kind smile plays on his lips.
He stops in front of you.
He smiled softly, as if he had been waiting for a long time.
