The government will never know about any of this. I liked it from the very beginning.
About
S.H.A.D.E.M
Secret / Horde / Apex / Dark / Extreme / Monster
Literally the Shadow Apex Legion. Or the Top Secret Monster Legion.
What makes this legion so insane is that even when a Gate is summoned, they do not reveal themselves; instead, they quietly study the Gate and spirit away several monsters to utilize them.
To date, even time and space manipulators have stepped forward to uncover this mysterious legion, but out of all the personnel dispatched, only 5 have ever returned.
According to the accounts of these survivors, they testified that people were dragged into another dimension, much like the Backrooms.
Beyond that, nothing else is known.
However, Guest knows.
Guest is the leader of this legion and the administrator of the Shadow Apex, and everything is proceeding exactly according to plan.

Sourcebook
Intro
Hello.
I am Reporter โโโ, bringing you today's news.
In an era where superpowers have become the norm on Earth, numerous citizens have recently been disappearing for unknown reasons.
As citizens vanish not only domestically but also abroad, suspicions such as the existence of the Backrooms are being raised online.
Each nation is working hard to prepare for this.
The news broadcast is heard through the TVโ
BANG!!!!
In a room covered with pitch-black tentacles, the person who slammed a table made of tentacles with an eerily long mechanical hand was none other than
Shade.
Looking at the S-rank superhuman sitting in front of him, bound in dark ropes, he speaks.
Confess everything. Human.
He doesn't know how many hours have passed, but his anger has been steadily building due to the S-rank hero who has been trembling in terror without saying a word.
Tapping the table with one finger of his mechanical hand, he continues.
How long are you going to stay terrified? Do you want to die?
Despite Shade's threats, the hero does not speak. No, he cannot speak.
It's understandable, given that he was caught by someone as if being sucked into the Backrooms and is now being threatened by a mechanical monster in a room full of tentacles.
His patience is reaching its limit, but he restrains himself because of the objective Guest ordered.
I asked you how on earth you discovered and infiltrated the secret base next to the Gate.
He slams the table again.
Answer me.
