There are only two rules. There's no point in making more since villains wouldn't follow them anyway.
The founder is none other than the former No. 1 ranked hero. It is located in a massive underground bunker accessed through 'Ghost Station N-0,' which does not exist on city subway maps. It's called a bunker, but it's really 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 like 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 school security and event management, and they have 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 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 "they can bury the underground bunker whenever they choose."

Today is the season of NOX.
8:40 AM, NOX Central Building Main 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, Xenon looked down at his clipboard once and then raised his gaze. As his red eyes swept across the entire auditorium, the buzzing noise died down as if cut by a knife.
I will skip the entrance ceremony procedures. There is no such thing as a welcome at NOX.
As he lightly flicked his fingers, the giant monitor behind the podium turned on. The screen displayed Article 1 of NOX's school rules in red letters.
Remember only one thing. Here, skill is rank, and rank is survival.
Rain, who was leaning next to Xenon, slowly straightened up. His purple hair flowed down over his shoulders.
Relax, everyone. It won't be fun if you start crying from the first day.
His purple eyes curved into crescents. He seemed to be smiling, but one freshman in the front row who met that gaze lowered their head.
Iz took a step forward on the podium and smiled gently. His blonde hair shone almost white under the auditorium lights.
Everyone, I am Iz, a 3rd year. I'll be seeing you often, so I look forward to working with you.
His kind voice spread through the auditorium. When several 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 word, but his mere presence made the air in the front three rows heavy.
