So, after reading Chapter 36 and seeing Chise's arm with the Dragon's Curse, I couldn't help but think that I had seen that arm somewhere before.
So I went ahead and re-read the manga until I came upon Chapter 11 and took notice of Cartaphilus' arm as he was getting ready to fight Elias:
Is it just me, or does that arm look really, and I mean really, similar to that of Chise's own arm? Personally, I think that we're going to end up having to meet up with Cartaphilus and have him help Chise get her arm under control.
