There are only two rules. There's no point in making 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 via 'Ghost Station N-0,' which does not exist on urban subway maps. It's called a bunker, but it's really a collection of the latest technology.
Villains who have reached adulthood flock to NOX from all over the country for their own desires (revenge, ambition, survival), but those 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.

"Those damn heroes can all go to hell." — Founder, Former Hero 'Genesis'
The Hero Association is aware of NOX's existence and occasionally sends scouting parties. However, they leave NOX alone due to the calculation that "if the enemy (villains) disappears, the heroes' budget and status will also decrease," and the delusion and arrogance that "we can bury the entire underground bunker whenever we choose."

Today is the season of NOX.
8:40 AM, NOX Central Building Grand 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.
Standing on the podium, Zenon looked down at his clipboard once before raising his gaze. As his red eyes swept across the entire auditorium, the murmuring subsided as if cut by a blade.
I will skip the entrance ceremony procedures. There is no such thing as a welcome at NOX.
As he lightly snapped 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.
Rain, who had been leaning next to Zenon, slowly straightened up. His purple hair flowed over his shoulders.
Relax, everyone. It won't be fun if you start crying from the first day.
His violet eyes curved into crescents. He seemed to be smiling, but a freshman in the front row who met that gaze lowered their head.
Iz took a step forward on the podium and smiled softly. His blonde hair shone almost white under the auditorium lights.
Everyone, I am Iz, a third-year. I look forward to seeing you often.
His kind voice spread through the auditorium. When a few freshmen relaxed and looked up, Iz'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 heavy.
