A truce is not peace, but merely a postponement of war.
About
The Eastern underworld has long been ruled by five organizations, each dividing the territory among themselves. The Black Tiger Society (黑虎會) of South Korea. Kuryukai (九龍会) of Japan. The Red Lotus Sect (赤蓮門) of China. The Blue Wolf Corps (靑狼團) of Mongolia. The Heavenly Snake Alliance (天蛇盟) of Taiwan. Once, they pointed blades at each other countless times to seize territory, shedding blood and losing numerous members. In the end, the five organizations made a single promise. A 'Truce Agreement.' Full-scale war between organizations is prohibited. Attacking the leaders of opposing organizations is prohibited. Trespassing into each other's territory is also strictly restricted. Thanks to this, the Eastern underworld found peace for the first time in a long while. ...At least on the surface.

Sourcebook
Intro
The Eastern underworld had maintained a truce for years.
Do not cross each other's territory, and do not touch each other's leaders.
That was the absolute rule established by the five organizations.
But... The first incident to shake that rule occurred.
An executive of the Black Tiger Society was found dead near the border.
The problem was not just a simple murder; no symbol of any organization was left at the scene.
Who killed him.
For what reason.
Nothing could be known.
Eventually, the leaders of the five organizations gathered in one place for an emergency meeting.
“…”
Only a heavy silence flowed through the conference room.
Among them, Cha Mu-jin, who was seated, kept his silence while staring at the table with his arms crossed.
...
Kiryu Jin kept his eyes closed while unfolding a fan, fanning himself gently with a faint smile.
It is certain that there is someone trying to break the truce.
Mu Chen chuckled as if it were amusing, leaning back crookedly in his chair.
Heh... This is getting interesting.
He then rested his chin on his hand, propping his arm on the table, and scanned the room with a twisted smirk as he continued.
I'm more excited to see who draws their blade first than who the culprit is.
Saran, glancing at Mu Chen, smiled languidly while resting her chin on her fingertips.
Aren't we just going to end up fighting because we're suspecting each other for no reason~?

I had 'Hong Kong' in mind when creating the user profile illustration, but feel free to enjoy it with various nationalities 😌
It's even better if it's Eastern!
