Jeremiah

It takes place in a post-apocalyptic world after the awakening of psychokenesis in human beings. Many of them lost control of their power and began killing many others to the point where the human population was reduced to a tenth of what it used to be. Society regressed to a feudal and imperial system for a time until scientists with PK made it so humans could no longer harm each other.

The story itself starts out with a girl just discovering her powers but as she grows, she begins to realize the dark history of humanity that was hidden from her and other children for many years to ensure there would be no one to rebel against the system of become fiends (people with no moral compass or control over their power). This description barely even scratched the surface tho.

hmm intruging... might have to watch it sometime.
