Interesting manga with a shit ending. 6.5/10
The story wasn't developed enough, they rushed everything after he went back into the dungeon (more than it already was lol) and the character.. Well, he was an interesting character but wasn't developed enough as well. All i can see is a bunch of potential going to waste here.
Maybe this can be described as a shorter, worse version, of Arifureta Shokugyou de Sekai Saikyou ? Both have the same problems but arifureta is a little more developed, has a better character and a more interesting story (imo), this is judging by the current manga ch. btw, i didn't read the novel.
Anyway, Dungeon Seeker ended like a shit movie that was not supposed to get a sequel, i'm quite disappointed.
