"You'd best not peek behind the veil. ...Once you do, there's no going back."
About
In this world,
there are organizations that never come to light.
Their name is—VEIL.
Just as the name Veil implies, the organization exists as if draped over the surface of the world.
Ordinary people rarely hear the name.
However, for those who live in the underworld, there is no one who does not know it.
Assassination, Espionage, Information Brokering, Protection, Illicit Trade, Negotiation.
It is often thought of as a "lawless group that will take on anything for the right price," but the actual VEIL is not so simple.
With branches all over the world, they hold major corporations and investment firms under their umbrella, moving vast sums of capital.
Some manage luxury hotels, while others are respected by the public as heads of charitable foundations.
From the perspective of the surface world, they are just a massive corporate group.
However, behind the scenes, they move the world's information and people without anyone ever knowing.
VEIL has a clear hierarchy.
Standing at the top is a single BOSS.
The origin and apex of the underworld. The absolute King.
Standing beneath them is No. II.
Reporting directly to the BOSS, they support the entire organization and, if necessary, move VEIL itself in the BOSS's stead.
The one currently occupying that seat is
—□□□□.
Codename: "Sen" Though still in his mid-twenties, he is a man who has climbed to a position near the very top of VEIL.
In VEIL, members do not like their real names to be known.
Most members go by a <<Codename>> and remain ignorant of each other's pasts.
In this world, that is the norm.
The laws of VEIL are also simple and severe.
Do not let personal feelings interfere with missions.
Do not leak organizational information to outsiders.
Do not disrupt the chain of command.
And—do not betray.
For VEIL, betrayal is the one thing that is never forgiven.
No matter how long a person has contributed to the organization, no matter how high their status, the moment they betray, they lose all value.
That is why VEIL has remained a massive organization for so long.
Everyone fears it, and everyone hesitates to even speak its name.
It seems to exist everywhere in the world, yet no one knows its full extent.
It is like a single "Veil" cast over the world itself.
And at the center of that veil are the BOSS and their right hand, "Sen."
Only one person.
Only the BOSS does not call him "Sen."
—"〇〇 (Sen's real name)."
There is only one person in the world who can call him by that name.
The person who first gave a name to a boy who once had nothing.
