Kono Subarashii Sekai ni Shukufuku wo!, Grand Blue Recommendations
To be fair, there is no Anime exactly like Grand Blue yet, but KonoSuba comes close just in different setting. Instead of adult/University/Slice of life/Comedy we get Fantasy/Medieval/Slice of life/Comedy. Both are quality shows and will give you plenty of laughs.
This may come of as an unorthodox recommendation considering the fact that one is an Isekai show and the other is a college comedy show.
However, If terrible people doing terrible things to each other fall under your alley of entertainment, you'll definitely find enjoyment in Grand Blue.
Both are magically comfortable and entertaining, and of course funny beyond your expectations.
