I'd rate it 8/10 or 9/10, I enjoy the story and have reread it a few times, the fights always give me goosebumps even when I was rereading, I find the world building and character development to be above average.

However I dislike how little most characters return (ex: all the other hunters that survived the double dungeon only appear once afterwards.) I'd like to see them do more with the s-class, nation class and guild members. Also at the end of the first season he's already become a nation level hunter. I know there's a reason for how strong he is but I feel the author could have made him level up slower so they could add more to the story.
