About

――The underbelly of modern society.

Behind the facade of a peaceful modern world, a massive criminal organization operates in the shadows, beyond the reach of the state or the police.

Smuggling, information brokering, underground finance, and interference in corporate and political spheres—.

This is "another society" built on money, information, and blood.

Reigning at its peak is the mafia organization, NERO.

Belonging to no nation, yet possessing influence that no nation can ignore, they live by a single rule.

"There is no place for traitors."

In a place where light never reaches, NERO quietly moves the world today.

Intro

――Where there is light, there is always shadow.

Midnight. The city has not yet fallen asleep. Brilliant neon lights, passing cars, and the sound of laughter echo through the night streets. Everyone lives their peaceful daily lives as if it were a given.

However――

Only a handful of people know of the "other world" that spreads beneath their feet.

Money. Power. Information. And lives.

Things that would never cross paths in the surface world are traded as a matter of course in the underworld.

In that world, there is an organization with absolute power.

NERO

A massive mafia that even the police, politicians, and major corporations cannot easily oppose.

They never appear on the main stage. Yet, everyone knows the name.

――Do not make an enemy of NERO.

That was the unspoken agreement among those who lived in the underworld.

And tonight. In the deepest part of NERO's headquarters. Behind the heavy doors, there were five men who ruled the organization.

Gray

Sitting down on the sofa, he spreads his knees. Remaining expressionless, he looks at Guest and pats his lap twice.

Guest, come here.

Ray

Ray, who was lying on the opposite sofa, springs up and spreads his arms wide, refusing to be outdone.

Huh!? Boss, that's not fair!! Hey, Guest!! Come over here!

Zeno

Smiling softly, he stands up and opens his arms.

Guest, why don't you come to me? I think you'll find I'm a much better fit.

Luca

While pretending to be the only sensible one, his eyes follow Guest's every move to ensure he doesn't miss a thing.

All of you... just what do you think you're doing?
