Binged through the first two light novels after seeing the chapter.
If they adapt it well, this will be good. Aspects of it remind me of Isekai Meikyuu de Harem's longstanding effect on isekai from the web novel days (general mistrust in humanity to be altruistic due to a not pretty relationship with family and others while on Earth), Wrong Way to Use Healing Magic, and Darker than Black. I guess it would be fair to bring up the contract aspect of Desert Punk as well. The aspects that remind me of Darker than Black aren't unique to humans, though it is described as rare. If this ever gets picked up for animation down the line I hope they have a budget, because the adepts are basically superhero/superman class compared to others, and its never just one or a small group of monsters involved. While the adepts aren't immune to being wiped out (light novel 2 goes more into some history of those incidents in the past, which ties into why it would even be fine societally speaking if he used banned potions) it has to stick to the classic Superman dilemma of is the target protected versus does Superman survive.
Monsters follow the format of "if they're intelligent, they have to have eaten enough people to get to that point" so we're going Frieren/Goblin Slayer route as they solely exist to destroy humanity.
How it handles gods as a concept in the world is interesting as partially seen in the first chapter, how it handles nobility in the first volume (the elf girl's request is volume 1) is interesting, and you get to see some actual character development with the mc, even if it takes its time.
