Yo an LN enjoyer here. I am a huge fan of the light novel and pretty much will only read the manga because I enjoyed the source material. Anyways, from what I can gather this is a really bad manga adaptation. I've read a few chapters and can say that it doesn't really go according to what happens in the LN, skips a bunch of content, and struggles to maintain the original plot. However, considering how complex the source material is and how manga panels can't really convey what the author is trying to say (eg. there is a lot of description, internal dialogue, etc. in the LN), it makes sense as to why the manga would fall short. Anyways, if you slightly enjoyed the manga but were disappointed with the execution, I'd highly recommend the source material if you like light novels. If you're curious on my rating, I'd rate this manga a solid 5.7/10 and the light novel a 9.8/10.
