Mikakunin de Shinkoukei, Gochuumon wa Usagi Desu ka? Recommendations
Both are comedic slice of life shows with mostly female characters. They both also have one character with a younger sister obsession, which is often entertaining, and there are some supernatural elements in both. Gochuumon does not really have any romance, aside from some yuri undertones. Romance is a feature of Mikakunin, though it is not as prevalent as you might expect given the name of the show. Both are very enjoyable and really quite funny.
