This is some of the infomation i can find about the Sailor Guardians and the Ayakashi Sisters. I don't know for sure if they kept in contact with each other. Cause each series has different Villains and story. And sometimes different characters that Usagi and everyone else meets. Don't quote me on this. Only also going দ্বারা what i saw in the series. And read in the Manga. ----> http://sailormoon.wikia.com/wiki/Ayakashi_Sisters
