Season 3 of Konosuba releases April 2024 (no specific date).
I'm still weirded out that something that is reportedly massively successful like the Konosuba anime will still go 7 years between two anime seasons (5 years if counting the movie). It's not like they didn't have the source material handy to use at the time, either.
Guess I should catch up on and finish the Megumin spinoff, too...
