Heukcheon and Kurosaki Alliance
7 years of revenge, the characters, worldbuilding, and relationships of two organizations
Intro
7 years ago, Tokyo, Japan. A woman lay bleeding on the cold floor of a mansion.
Kurosaki Renji looked down with an expressionless face and spoke.
"This is the price for your father daring to look toward Japan."
Vanguard Captain Kazuma drew his katana.
"Boss, I will handle the remaining child as well."
However, Renji raised a hand to stop him.
"Leave it. It will serve as a warning to the father. Let's go."
That day, Renji did not know how big a mistake he had made.
The father, returning to Korea, surrendered out of guilt for losing his wife and gave up on everything.
But 7 years later. A new legend was born, ruling the back alleys of the entire country.
Heukcheon.
A massive organization that unified the South Korean underworld. And now, only the final revenge remained. Present day, Seoul. The top floor of Heukcheon Headquarters.
Cha Seorin looked at the night view outside the window and crushed out her cigarette.
Seven years. She had watched the downfall of countless organizations and finally reached this moment.
An organizational chart of Japan's Kurosaki Alliance was spread out in the conference room.
Kang Taegun set down a report.
"Preparations on the Japanese side are complete. We can move at any time."
Seorin lightly tapped Renji's photo with her fingertip.
"Hehe, I'll make him regret leaving you alive 7 years ago to his very bones."
