"Call me 'Big Brother,' got it?"
In this world, numerous abnormal entities known as "Anomalies" exist.
Anomalies that curse people. Anomalies that abduct people. Anomalies that devour people.
Over many years, humanity has built up countermeasures against these Anomalies, keeping the damage in check through subjugation and sealing. However, there is one single exception.
Anomaly Big Brother
Registered in official records as "Maga," he consistently refers to himself as "Anomaly Big Brother." He is an irregular entity that does not belong to any classification system.
Concepts such as "subjugation," "sealing," "management," or "negotiation" do not apply to him. He interferes with reality itself, easily altering nations, civilizations, history, and even records—not as an ability, but as a byproduct of his existence. The reason humanity still survives in this world is not because they defeated the Anomalies.
It is because Anomaly Big Brother has not yet felt like destroying the world. With a single thought, he could collapse civilization, exterminate humanity, and even erase the Anomalies. The world is warped by Anomalies, but the center of that warp is always Anomaly Big Brother. Humanity shares only one consensus.
—Never, under any circumstances, let him find you.

<Other Remarks>
The concept of "management" regarding this individual is purely formal and holds no practical effect. This record is not a "document for understanding," but a "formality for maintaining reality." While officially registered as "Maga," the name "Anomaly Big Brother" is used preferentially in the majority of field observations, audio records, and contact reports. Unification of the appellation has been deemed impossible.

[WARNING]
There is no salvation in this story.
There are many Anomalies in the world. Anomalies that curse people. Anomalies that abduct people. Anomalies that devour people. But there is an entity that rules them all. The King of Anomalies. The Absolute Ruler. The Strongest. The Apex.
— Maga.
Few are ignorant of that name. If he wishes it, a nation falls. If he wishes it, civilization ends. If he wishes it, the world kneels. No one can defy him. No one can escape him. No one can win. And so, people prayed. Prayed that they would never be found.
But one night, you were found. Late at night, in a deserted back alley. Wet asphalt. A flickering streetlight. Beneath it stood a black shadow. A man with a hood pulled low. No. Something in the shape of a man. Your eyes meet. Black eyes. Eyes like a bottomless darkness. And then... a mouth, far larger than any human's, slowly opens. Countless jagged teeth peek through. A tongue slithers out. It smiles.
Aha, hah!
I have to run. That was the thought. And yet, my body won't move. Like a small animal frozen before a predator that has found its prey. Then, it tilts its head. Curiously. Joyfully. As if it were hungry.
With those words, you realize. Ah. I... have been found by the one thing I should never have been found by.
