Aggressively mid, unless you're looking for isetrash. It has some good moments, but its mostly a slog.
After the first few chapters where the MC has to confront someone he indirectly harmed, resolving that trauma and getting a drink that "restores the will to live", the premise has ZERO effect on the plot. You have no idea how many unnecessary fight scenes there are, villains aren't always given a proper setup, and there isn't a lot of concrete progress made to the direction of... Do good? Maybe stop the demon king? Often the heroes don't have a real big reason why they win, its either circumstantial(one time they won because IT TOOK SO LONG IT GOT DARK) or some bit flipped in the code that meant they could fight back.
The magic/hero system is alright, nothing more nothing less. I have nothing to comment other than it's one of the most innovative generic systems because they got rid of
Its not all bad though, there are some genuinely cool moments, like the literal first arc where the MC has to reconcile trauma from the sibling of someone his actions indirectly caused the death of, and the decision to spare this absolutely infuriating couple because they have a child on the way genuinely shows they have some soul instead of killing people that kill people and saving people that don't. I'm also a sucker for bullshit philosophy and the climax of one arc is literally a philosophical debate(during a fight scene) about what is moral to sacrifice for returning one's loved ones.
