- Description from novelbuddy

Luke transmigrates as Abel Bishop into an alternate world vastly different from his own. On the surface, it appears ordinary, but beneath lies a hidden war.A special group of people, known as Occultists, wield supernatural abilities to combat the anomalous entities that threaten humanity's existence.Thrown headfirst into this age-old conflict, Abel has only his strange abilities, his sheer will to survive, and a mysterious coin that always returns no matter how many times he tries to get rid of it...

When Simon dies, it turns out there's more to combat than lightning reflexes with his controller, and the path to becoming a hero is more brutal than he can imagine as he descends into The Pit. Death after Death is a dark, time loop/Isesaki story with roguelike elements, that explores some of the common tropes in a different light.
