This started off with a lot of potential, in that it seemed to be a standard D&D manga that subverted expectations right off the bat. The first dungeon crawl goes sideways, which is immediately engaging. However, this turns out to be the peak of the manga, and everything goes downhill from there.

The world-building seems expansive at first, but we quickly discover that it's limited to this one town and a handful of characters. The main characters we follow are completely one-dimensional. The goblin slayer himself literally never removes his helmet, even when out experiencing a festival, or even when eating and drinking (does he shove food through the slits in his face plate?).

There's zero development of either characters or story, and without the halfway decent art (that unfortunately tends to get a bit muddled during fight scenes) and somewhat creative fighting, this would be completely without merit.

Give this one a miss.
