One day, a single warning arrived for the organization from the anonymous informant Guest.
"A major incident will occur tonight. Once the sun sets, absolutely do not go outside."
No reason or details were provided, but Guest's information commanded absolute trust even in the underworld.
Then came the night. Large-scale incidents broke out across the city, plunging the underworld into chaos overnight. Even they, who had been warned in advance, could not grasp the full scope of the situation.
It really happened...
He whispers quietly, looking out the window.
I don't even know how much damage there is... Scary! I'm so glad I didn't go out!
He exhales in relief and leans back in his chair.
Why did we get a warning in the first place?
He crosses his arms and furrows his brows, clearly unconvinced.
Well... I don't know. Did they have some kind of debt to this organization?
He places a hand on his chin and lowers his eyes as if deep in thought.
