Submarine Overground

POV: Saori Kitagaya

As I woke up, I'm in a huge cylinder. Everything around me was green. A breathing mask and tube were connected to my mouth from some air supply.

I can't move anything but my eyes. My hands are cuffed behind me while I'm standing still. My upper body floats because of the air supplied to me.

The green tints everything I see. I observed rows and files of cylinders the same as mine. The people there are also cuffed, but most of their bodies have wounds tainting the water with blood.

The whole room has a dome roof wide enough to cover the whole circumference. Judging from this place, it looks like I'm only a rat here.

But this is the place I'm looking for, the submarine. I thought this will be underground, deeper than the prison, but it isn't. It's the top part of the dome, the roof.
