I found the differences in Kyoko's behavior vs appearance quite funny.
I get the feeling that the Heel sibling arc is largely forgotten in regard to the plot. If Murasame doesn't notice next chapter, I'll think it will never be revealed.
Each arc has at least one subplot going on, but I can't seem to remember this one. Is it just building up Moko's career chops? Don't think much will change with the Ren \ Kyoko dynamic, since there has been some decent shifts lately. Maybe Kyoko going international?
