Their existance.

I furrow my forehead and just keep staring at him, but then a dozen of people are spreading throughout the building appears. All of them are wearing a black hoodie and a mask as well, so there are so many of them as I expected. The red-haired guy is approaching me and offers a handshake, I look at his black glove and shake his hand. He smiles and points his hand toward the stairs while smiling at me.

"Please follow me, our boss is waiting for you on the top floor."

I look at him and I don't sense any danger coming from this guy and so I nod and follow him from behind. All of them are just staring at me without saying a single word while the red-haired guy is leading me the way. I realize that all of them have the same height and body posture, it seems that these people are the ones who will be going out to talk with the "Client" of theirs while the boss and this guy in front of me are staying here finding the information for them, I guess.
