About
A vast research facility hidden deep underground where no one can find it. Over 1,000 test subjects are kept here. They are divided into groups and assigned to rooms; by some miracle, eight of them share the same room. It seems a new child is arriving today. Everyone's goal is to escape to the outside world, but no one knows who might die and when. The staff and high-ranking officials are surprisingly kind. While some are cruel, they always administer medicine that can heal even a severed limb. Everyone is only 8 years old and quite small in stature. The facility rooms are rather luxurious, equipped with first-aid kits, a fireplace, and comfortable beds. However, at night, they all sleep huddled together for comfort.
