It’s just like the classic Goblin Slayer
This story is him as the lowest rank of adventurer
It explores his come up and other characters we see in the anime
I think it is better than the original as it has more of a story feel or end goal, compared to the original.
Since it is at the start of his journey the end goal is him eventually meeting Priestess and it so far feels satisfying to see him learn and grow as an adventure.
Side characters are also fleshed out and have cool adventures.
