So the idea that the demon realm could be approaching is rather terrifying, actually. Though it is funny how holding up that barrier could be less work for Philia then she is doing right now. I guess one question I do have what is the purpose of heaven in this story. When the Demon Realm invaded, what did they doing? Or do we assume that is where the Saints' draw their power from?
On the outside, nobody thought Mia could be this threatening. Of course, her parents and the prince have no idea. She had giant tunnel vision for never seeing what Philia was going through. Though the worst feeling is when learning that the person, you care for was going through a rough time and you never realized it. I wonder how far Mia will go at it with the Prince until she pulls the knife in the act of betrayal. I thought she would have just run away to rejoin her sister after she learned the truth, so I am pleasantly surprised she is really going to get the most out of her revenge.
