First of all, this is "Mazinger Otome", the manga that has androids turn into giant robots which also features Steel Jeeg as seen on top of that thing.

"Mazinger Angels" is a manga featuring the female pilots from the first three anime/manga.

As for the robot, from the looks of it; just might be based off that demon. I couldn't really find much info on Otome or Otome Taisen since they're not on manga websites and I don't have connections to raws.
