What about Maitake2 who draws her as a useless lesbian (which I think is very very cannon)
Well, the person you're asking has posted comments on the majority of Maitake2's works insisting that "Homaru" would never behave that way, and further, that the belief that Homura isn't always topping is some kind of psychosis.
My personal belief, and take this with as many grains of salt as you need, is that devil!Homura would probably top, if only to keep up the thin veneer of control that she's holding on to by her fingernails. This does play into some of Maitake2's stuff, but there you go.
