Full image of the announcement page released on Dengeki today:
So SF stands for both Scifi but also Sukoshi Fushigi (in furigana) which is low fantasy.
The scientist’s name is Himesaki Kasane, she’s the landlady of their share house & also a “bug” researcher. The MC is Otaya Kon, who will be her assistant. Synopsis for the first chapter releasing next month (10/27 JP) is that the whole town gets turned into a jungle because of a “bug.”
It’s most likely not real bugs the story is dealing with considering they’re katakana in quotations. The way the series title is written is pretty odd, but “Kami-sama ga machigaeru” is technically “God is wrong/mistaken.”
Edit: Nakatani mentioned on Twitter that if she continues writing what she wants, she will come back to yuri again eventually. Hats off to her for following through with writing fantasy like she said in an interview way back when.
