@schappi I wouldn't actually bank on something like that existing. It does scream of being a lot of work lol.
Checking both things (the source and adaption) takes quite some time. I did that myself once with Goblin Slayer.
The short verdict: pretty faithful even though they reordered stuff a bit to have a more interesting ending when adapting the first 2 volumes of the Novel. Some bending of certain scenes was required.
But let me know if you find something!
