Is it just me, or did I skip the part where they gave us a clue about who the he** this fake blood demon is!. The man said he didn't tell them that he was the blood demon. So why cope the mask and sword then and most importantly where did he get the sword from. 
I don't know but it looks like this whole chapter just left me with more questions than any answers.
I am looking but I can't see where you said you were the author 
because I was pretty sure I was talking to the author.
