Sorry don't know where you can find images of but I know of another anime called Devilman Lady (Devil Lady in the states)  Where if she can transform into a giant of her demon form.

I own the Devil Lady box set, it's maybe 40-50 bucks for the full series, with minimal extras.  It is excellent, some muscle growth, lots of feats of strength and clothes ripping… I.m surprised that nobody has mentioned it earlier.

And for those who have seen it… yes, the ending of Episode 25 blew my mind as well.
