The world has fallen for as long as I can remember. The dark side in the hearts of those who suffered the fall was infinitely magnified, turning them into monsters who took pleasure in killing humans. The surviving people moved to various new territories carrying the beliefs of the dead, living with fear and despair. But now, the next fall is coming, and only "remains" can save mankind.
I am a trapped person, and my duty to survive here is... To help the "remains" find themselves.
Motto: No matter what happens, don't lose yourself.
