Nightmare Apostle

[Synopsis: In this age of prosperity, a society swept up in material desire is brewing humanity's karmic burden.

When karmic flames ignite and fantasies of good and evil take shape as nightmares in the real world, Chu He discovers what it means to have a world of anime in hell.

A war zone roaring with gunfire! Demonic spirits running rampant in reality! The heroes of the past marching beneath the charge! Ghost slayers who give everything! As he stands before a strange spirit born from the memories of a hundred million people, the moment he slays a god begins!]

The synopsis has always been pretty weak, and I can't find the right hook. Just ignore it.
