High School Noir: Bully Gang Simulator

202X, Republic of Korea.
Violence was merely a pastime for unruly teenagers.
Disorganized, small-time gangs with no order or rules, extorting petty cash while fighting over neighborhood alleys.

Into that mire, seven monsters descended, shattering the existing 'hierarchy' completely.
Genius intellect and overwhelming power.

The birth of 『0th Gen』.

As the underworld across the nation was engulfed in shock, these seven predators crushed and unified the fragmented, third-rate gangs.

Thus, an unprecedented, nationwide, colossal syndicate,
『Iljinhoe』, was created by their hands.

"The era of beasts reeking of sweat on the streets is over.
From now on, violence must operate as a perfect corporate 'system'."

However, the romance of unification was short-lived.
Baek Cheon-hee, the pinnacle of the 0th Gen and their ruler, planned to transform the colossal syndicate they had created into a 'mega-corporation' focused on profit.

Three legends, who agreed with her ruthless capitalist madness, established three major subsidiaries.

The sadistic showman, the perfect assassin, and the psychopathic capitalist. The era where one wears bespoke suits instead of school uniforms, and buys lives with black cards instead of fists. The legal crime cartel 『Iljinhoe Corp.』 swallowed the world.

However, disgusted by the brutal corporatization that treated their comrades as disposable, the remaining three legends tore off their suits.

"Cheon-hee, you've become a monster consumed by capital.
We overturned this game in the first place... to protect our family, didn't we?"

The 'Yacha' of Incheon, the 'Haemu' of Busan, and the 'Geukya' of Cheonan.
Choosing romance and loyalty, these three established 『Independent Crews』 in their respective territories,
and declared all-out war on the great empire, Iljinhoe, which they themselves had built.

It is now 2026. A suffocating cold war between monsters in suits and beasts in tactical gear.
An era of tense balance where even Iljinhoe cannot easily provoke due to overwhelming force.

And at the center of this battlefield, the rotten heart of Iljinhoe.
A lawless zone teeming with mad dogs, vipers, and witches: 『Taehwa High School』.

Today, kicking down the tightly shut door of this suffocating hell...
To shatter the great food chain from the very bottom,

A single 'variable' enrolls.

"Get out of the way.
From now on, I make the rules of this rotten game."
