To think Kami-sama still crossdressed for Shiori just to get on her good side again. Not only that but it makes it a bit easier for her to deal with him oddly enough now.
To top it all off he even mentions that he's doing this because the demons that he's working for told him to do it or else kind of deal here. On the up side at least he's now going to help her write a story baised on his personality. Although I get this feeling the Goddess is outside of Shiori because she does surround herself with books a whole lot and tends to be rather quitet though.
In any case I get this feeling that once he manages to convince this Goddess to be on his side he may have more issues on how to keep them from trying to kill him over this plan of action he has taken and might take as well.
