The novel is pretty good. Other than the whole reincarnation B.S it's a nice read.
And my personal take on it is that the book actually uses the hunter theme pretty well.
It's not about dungeons and inter dimensional portals, Just about a guy that hunts monsters while looking for his sister.
I personally recommend it if you are looking for a nice hunter theme novel that's different from the rest of stories out there then this is just for you.
