Loved this chapter, a few bits icked me out though, the measures Riful took, and that last shot of Raphaela & Luciela is going to give me creeps. (If you stop and look then you realize that their eyes got juggled around a bit. *shudder*)
About the disgusting claymore bodies, it's never outright said, but they're meant to have some hideous scar/disfigurement roughly between their chest and waistline. Though judging from how badly people react it's probably something like actual Youma flesh grafted into them or something else yummy.
Just out of curiosity did anyone else do a double-take at where Helen's hand seemed to go? I know it didn't go there, but it made me look twice.
