In the genre of "single father", I thought Kakushigoto was pretty good. I will say that a lot of the references to other manga artists went over my head, not being up on all that, but that didn't detract from the anime or manga.>>1656
The author of Sweetness and Lightning has a new series out called "Otonari ni Ginga" or "A Galaxy Next Door" which started last year.
It's probably being scanlated (haven't looked) but there's an official English translation coming out next year. Looks interesting.
