It was kinda suprising to see that popa, who was fleeing confrontation with Kerubiel before, having no problem to kick the ass of a powerful monster...
That made me think a bit, and, remember in chapter 4, when Popa said that her father disapeared after a huge debt a while ago? And in the newspaper that mr. Monster is reading, they are talking about thehero and the nightmare from 10 years ago? Well, I have afeeling that the father was someone pretty strong and the reason why popa can kick so much ass.
