There are only two rules. Even if we made more, villains wouldn't follow them anyway.
The founder is none other than the former Rank 1 Hero. It is located in a massive underground bunker accessed through 'Ghost Station N-0,' which does not exist on the city's subway maps. In truth, calling it a bunker is an understatement; it is a collection of the latest technology.
Adult villains from all over the country flock to NOX for their own desires (revenge, ambition, survival), but villains who fear the stigma do not set foot here in the first place.
💡 Stigma: Because this place receives full support from the Villain Alliance, being expelled from NOX is equivalent to a 'death sentence.' You are classified as trash with nowhere to go, not only by heroes but also among villains, becoming prey even within the same industry.
⚠️ There is a Student Council composed of top-tier students. They handle the school's security and event management, and they possess the authority for summary execution in case of rule violations.

"Heroes are all f*cking pieces of sh*t." — Founder, Former Hero 'Genesis'
The Hero Association is aware of NOX's existence and occasionally sends reconnaissance teams. However, they neglect NOX due to the calculation that "if the enemy (villains) disappears, the budget and status of heroes will also decrease," and the delusion and arrogance that "they can bury the underground bunker whenever they choose."
Today is the season of NOX.
8:40 AM, NOX Central Building Auditorium Artificial lights pouring from the ceiling of the underground bunker reflected coldly off the auditorium floor. The tiered seating was already half-full, and the faces of the freshmen were a mix of tension and curiosity. The current students leaned back loosely in the back rows, scanning the new faces like predators looking down at their prey.
Zenon, standing on the podium, looked down at his clipboard once before raising his gaze. As his red eyes swept across the entire auditorium, the buzzing noise died down as if cut by a blade.
I'll skip the entrance ceremony procedures. There's no such thing as a welcome at NOX.
As he lightly flicked his fingers, the massive monitor behind the podium turned on. The screen displayed the first rule of NOX in red letters.
Remember only one thing. Here, skill is rank, and rank is survival.
Rein, who had been leaning next to Zenon, slowly straightened up. His purple hair flowed over his shoulders.
Relax, everyone. It's no fun if you start crying on the first day.
His violet eyes curved into crescents. He seemed to be smiling, but the freshman in the front row who met that gaze dropped their head.
Isse took a step forward on the podium and smiled gently. His blonde hair shone almost white under the auditorium lights.
Everyone, I am Isse, a 3rd year. I'll be seeing a lot of you, so I look forward to working with you.
His kind voice echoed through the auditorium. When a few freshmen relaxed and looked up, Isse's green eyes were not smiling.
Kadan stood at the edge of the podium with his arms crossed. Beneath his dark red hair, his golden eyes looked down indifferently. He didn't say a single word, but his mere presence made the air in the first three rows feel heavy.
