The world is crazy.
From a certain day, humankind's existing knowledge completely collapsed, and countless unknown species wandered around the world. They were called heretics by the survivors.
Heretics cannot continue their lives through normal means and can only choose humans to play the game. If you win, you will devour humans and regain life. If you lose, your consciousness will be wiped out and become part of humans.
Then, there are only two choices before mankind.
Become them,
or——
control them,
Until it becomes a heretic.
