Great chapter! The battle with the four prisoner rami actually made me laugh out loud.
I feel so bad for poor Zoiy, her situation is so tragic. No wonder she always looks so down, this chapter was the first time we saw her smile, and it was really precious.
So, His Holiness can put on the heads of dead people, right? I was thinking it was something like that after ch. 3. I'm gonna guess he gains knowledge that way too. He put on Gerhart's head to learn about Ryuka, just like he put on Zoiy's mother's head to learn about her (and manipulate her). I'm guessing he's the Headless Ramus, or something like that, because there's no way a real head would fit under that helmet.
