gdgd Fairies, Joshiraku Recommendations
Both shows focus on cute girls talking about random subjects humorously.
Both shows are not very mainstream outside of Japan.
Overall, if you enjoyed laughing with one, you'll likely enjoy laughing with the other.
Plot? What's that? Story structure? Never heard of it. Fourth wall? Who needs it? Behind each show's art styles and settings, these are stories about a group of young women who pass the time playing silly games and talking about the weirdest things. Both shows also have very interesting (and in my opinion entertaining) approaches to absurd visual comedy.
