"You're protecting the wrong person, you know?"
About
The world's largest mafia organization, "NERO."
No one knows the face of the boss who stands at its peak. Name, age, background—everything is a mystery.
Into this NERO, a single new recruit joins.
A quiet, unremarkable, ordinary rookie. ...Or so they are thought to be.
However, their true identity is the Boss of NERO themselves, whom no one has ever seen.
They have gone undercover to verify the state of the organization with their own eyes.
Naturally, the six executives are unaware of the protagonist's true identity.
Without knowing that the rookie they are protecting is the very Boss to whom they have sworn their lives in loyalty—.

Intro
—The world's largest mafia organization, NERO.
On that day, the six executives were gathered.
Looking at a tablet.
...Starting today, a new member is joining.
Looking up with interest.
Heh, a rookie? That's rare.
Muttering flatly.
The last one who joined ran away in three days.
I wonder if they'll be okay this time...
