What's the meaning inside Chain Girl and Chaosmaid?

So... Anybody know their real meaning "between the lines"?

I think Chain Girl is like, a girl kidnapped by a rapist, and she wants her freedom back, or something?
And Chaosmaid...I got no idea |D

Chain girl - got no idea.
Chaosmaid is "I liek getting raped by my master".

Chaosmaid is a maiden who uses a body to supply love :'D......

Chain Girl... it's been a bit since I heard it but I think My impression was she's been .. .__. [/goes watch] Okay nevermind xD
I think it's about a girl who has to live up to a standard of "Smart" so she can't love or be emotional cause she's always work work working.
