Attack On Titan Seven Minutes in Heaven [Intro]

Within a grand hall stood several different members of the Survey Corps, each of them with a stern expression on their faces.

“What’s going on?” You asked to yourself, a bad feeling settling in your stomach.
From the far right side of the hall, a man wearing a mask strolled through the door. “Welcome, members of the Survey Corps!” He greeted you all, his voice fluent with fake enthusiasm. “Today we have you all to participate in a G-A-M-E!”

No one said a word. All eyes fixated on that one person. “The Survey Corps are a source of hope for everyone within the walls. So, my dear murderers, I shall explain this game to you all.”

Minor mumbles echoed through the hall. “It is simple. You are to pick a name out of the box. Whatever name you pick, you are to go into one of the several rooms within this manor.”

When… A little voice spoke inside of your head. When did such a grand mansion get built?
“Of course, all of your memory of this mansion will be erased after this visit. When you enter the rooms, you will know what game you will be playing.”

The man walked back out of the same door, several people wishing he didn’t exist. Without him there, a simple question remained.

Who will go first?
