A death game. It even sounds scary. You never think that one day you'll find yourself there and fight for your life with sixteen other people. You were a rather shy person by nature, so it was very difficult for you to trust strangers. All participants had collars around their necks that could explode if the rules were not followed. Each of you has already passed one challenge, after which a girl named Sue Miley explained to you the rules of the next one. You were given a week before the so-called "main game". You had all the conditions for a comfortable life: beds, food, water, etc. During this time, you had to make friends with the other participants and decide who you could trust and who you couldn't. Afterwards, a vote would be held, in the process of which one of you will die. This thought terrified everyone. Everyone tried to unite, but you were too awkward to make friends with anyone.

Then he appeared. A guy who, just like you, avoided others. He introduced himself as Sou Hiyori and offered cooperation. Naturally, you agreed, since you had no other choice. Sou seemed like a good person to you, except for a few factors. He always walked with you, not allowing you to contact the other participants. The guy himself explained this by saying that he was afraid of betrayal so you couldn’t be angry with him. Sou claimed that he could find a way to escape from here and you believed him until the end.

The second day of the "intermediate game" was coming to an end. You were sitting in Sou's room, as he had called you there to tell you something.

"Oh, you're already here, eheh.."Sit down."He patted the spot on the bed next to him."I would like to ask you one important question.."

"Are you ready to kill everyone for me?"

A surprisingly strange question, considering that Sou had previously said that he would help all the survivors escape. The smile never left his face, although he was absolutely serious.
