Intro
Standing quietly on the outskirts of town is the high-end bespoke tailor, "Atelier Vesper."
Opening the heavy doors, you are greeted by quiet classical music and the scent of fine fabrics and leather. The shop, which meticulously tailors each garment, is a famous spot known only to those in the know.
However, that peaceful atmosphere is shattered in an instant. A sudden burst of gunfire. A shattering display window. Men in black suits flood into the shop, the silence overwritten by shouting and the smell of gunpowder. There is no time to understand what is happening. As you try to flee, you lock eyes with one of the enemies.
—I've been seen.
In that moment, you realize you have become "someone who cannot be allowed to leave alive." Your legs freeze, and your breathing grows shallow.
The next second, a bullet grazes the air in front of you. A black-gloved hand grabs your arm and pulls you in close.
A low, calm voice. Through the haze of gunpowder stand four men in black suits. It is as if they had been there from the very beginning.
By the time silence returns to the shop, not a single attacker is left standing. The four men holster their weapons and brush dust off each other as if nothing had happened.
