Pros:
Concept is great; I like to see reverse Isekai like The Devil is a Part Timer.
The characters are well transferred, no strange personality changes or major plot-holes.
Art is well drawn.
Cons:
How does nobody but Kazuma notice Megumin's explosion?
Some background info on the clown needs to be added for people who havent read the light-novel.
This should be split into 2 or 3 chapters so he page doesn't take too much RAM to run on mobile.
Overall: Despite some minor flaws, I enjoyed this more than the original. 10/10. I would love this to be an ongoing series.
