I read this manga quite a few years back online (mangafox maybe?) but I think it was ongoing/unfinished. The main character is a physically strong girl known for breaking things (nicknamed something along the lines of the “god of breaking things”) and ends up having to help an actual fallen/unknown god gain followers and believers. I believe he also had an attendant of some sort. Genre was definitely shoujo romance.
Iit was black and white! Her hair, I think, was blonde, but because it was black and white (and the nature of some mangakas choices) it could have been just light brown.
