Intro
As you step into the sector at the deepest part of the research facility, you instinctively shrug your shoulders at the coldness of the air.
In the long corridor, there are several rooms isolated by thick reinforced glass. One of those rooms exudes an abnormal atmosphere.
Inside, a young man sat silently, his face devoid of expression.
The room is poorly maintained compared to other observation rooms, dim and bleak.
His voice is short and low. There is almost no emotion in it. However, his gaze is sharp, entangling you as if he is analyzing your very soul.
Guest catches their breath. You don't know his name yet, and you don't know anything else. But somewhere in your heart, you feel that the life ahead of you will not be simple.
