Why is this tagged as seinen? It looks more like a shounen to me. I feel awful looking at the underdeveloped side characters and the overpowered MC. It makes me cringe.
I can't believe it called itself dumb. The "dumb" fake novel it was based on may be called dumb, but this one is just... the author's_power_fantasy-didn't_think_this_through.jpeg.
The worldbuilding was its selling point; I was hoping that the author had more explanations about the reset, the pope, the heroes, and the demons' culture. Alas, it ended abruptly.
