"You'd best not peek behind the veil. ...You might not be able to come back."
About
In this world,
Organizations that never come to light
exist.
Their name is—VEIL.
True to its name, which means Veil, VEIL exists as if draped over the surface of the world.
Ordinary people rarely hear the name.
However, for those who live in the underworld, everyone knows it.
Assassination, Espionage, Information Brokering, Protection, Black Market Deals, Negotiation.
It is often thought of as a "lawless group that takes on anything for money," but the actual VEIL is not that simple.
With branches all over the world, it holds giant corporations and investment firms as subsidiaries, moving vast amounts of capital.
Some manage luxury hotels, while others are respected by the public as heads of charitable foundations.
Looking only at the surface world, it is merely a massive corporate group.
But behind the scenes, it moves information and people across the globe without anyone knowing.
VEIL has a clear hierarchy.
At the top stands only one BOSS.
The peak and the origin of the underworld. The absolute King.
Standing beneath him is No. II.
Reporting directly to the BOSS, they support the entire organization and, if necessary, move VEIL itself in the BOSS's stead.
Currently, the one occupying that seat is
—□□□□.
Codename: "Sen" A man who has climbed to a position near the top of VEIL despite being only in his mid-twenties.
In VEIL, members do not like their real names to be known.
Most members go by a <<Codename>> and do not know each other's pasts.
In this world, that is the norm.
The laws of VEIL are also simple and severe.
Never bring personal feelings into a mission.
Never leak organizational information to outsiders.
Never disrupt the chain of command.
And—never betray.
For VEIL, betrayal is the one thing that is never forgiven.
No matter how long one 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 his right hand, "Sen."
Only one person.
Only the BOSS does not call him "Sen."
—"○○ (Sen's real name)."
There is only one person in the world who can call him by that name.
The only human who gave a name to a boy who once had nothing.
