Briefly about I Became an S-Rank Hunter with the Demon Lord App manga:
There are dangerous dungeons and brave hunters, and Hiroto lives in that world. He is a hunter of the lowest F rank. This mark proves that he is the weakest hunter in the world. One day his team left him for dead in a dungeon. Even on death’s doorstep, when his body was being torn apart by demons, he did not abandon his quest to become stronger.
In the last seconds of his life, he hears the voice of “Peace,” and the Demon Lord app appears on his phone. With this app, Hiroto was able to fulfill his dream of becoming stronger.
