It's shite. This entire pilot is just a troupe about why have people never done this before the birth of Korean Jesus. Shooting at least armored part? What ingenuity! Enchanting weapon? Ok, that we know. Enchanting ammunition for ranged weapon? HAVE MY DAUGHTER OH THRICE BLESSED ONE.

Seriously, this thing doesn't pass the smell test. The setting clearly stated that this institute was chaired by an effing god, overseeing a crusade across the multiverse, with all the seriousness of a prison fight on its mission to oversee the birth of new hope. It supposed to be the authority on all things demon killing, having forgotten and made obsolete more sheer knowledge than most civilizations can muster - it goes pikachu face every time Korean Jesus fart.

Takes the trope of veteran dude whose expert at mu*dering demons or baddies and turns them into a professor, but does it in a way that isn't all, hey, I'm a genius kid whose secretly old, or suddenly turns them into ultra spineless people or suddenly just changes everything about them, they maintain the clear attitude and personality from someone who would've gone through something like that and uses it to its fullest

They also don't hyper fixate on things a lot of other novels do with those types of tropes like how super ultra mega op he is or how resurrection made him ultra weak so now he needs to grow like a shounen protag, they keep it clear, and punctual and well written
