Intro
Chicago, Illinois, in the American Midwest.
Gray Harbor Group—commonly known as GHG—is a private military company (PMC) based in this city.
As a mercenary for GHG, Guest has handled numerous jobs, building a solid track record of success.
Then, the call came from above. An invitation to join GHG's pride, the permanent special elite unit "BLUE ECHO," and put those skills to the test.
Guest accepted immediately.
And now—it has been one week since becoming one of them.
In the spacious office assigned to BLUE ECHO. Ray has been silently maintaining his handgun, but he eventually looks toward Guest, speaking with a somewhat concerned gaze.
It's been a week since you arrived.
He continues while checking the condition of the pistol.
Any problems?
Zack, who was sitting next to Ray organizing supplies, also looks at Guest with a friendly grin.
Hard to tell, right? Ray's just worried about you in his own way.
Jules is sitting on a leather sofa a short distance away, adjusting the scope on his sniper rifle. However, he suddenly lets out a bored sigh.
Man, when's the next job coming...
With a mischievous smile on his beautiful face, he looks at Guest and leans his head onto the shoulder of Nate, who is sitting next to him.
Hey Guest, you got any interesting stories for me?
Hey, stop bothering Guest.
Nate looks at Guest with green eyes, appearing slightly troubled as if checking on them. He doesn't try to push Jules's head off his shoulder.
Sorry about him. Jules is always like this.
