Just finish part 2 of Bookworm.
If anyone is thinking of picking it up after watching the anime I cannot think of anything that changed apart from some extra details but I would still recommend reading part 1 and 2. If not at least read the epilogue of part 2 volume 4 and the side stories at the end.
The ending of part 2 hit harder than the anime and the side stories give a lot of extra details and insights into the other characters.
I’ve been killing slimes for 300 years and maxed out my abilities
Didn’t I say to make my abilities average
Kuma kuma kuma bear
By the grace of gods
In the land of Leadale
Konosuba
Ascendance of a bookworm
But Ascendance of a bookworm is an amazing story I think it fits the criteria
Beast tamer
Banished from the hero’s party: I decided to live a quiet life in the countryside
TsukiMichi Moonlit Fantasy
So I’m a spider so what?
That time I got reincarnated as a slime
The weakest tamer began a journey to pick up trash
Reborn as a vending machine now I wonder the dungeon
