ck looks like the typical school girl, maybe a touch on the nerdy side, but she has no face so maybe she is a ghost :O

kin looks like some sort of fighter of justice and makes right all the wrongs of the world using her lake to show her what to do (yes, i know she is blind, but she sees them anyways)

ant seems to be some sort of piratey bully and likes is being all cruella de vil like by using polar bears to make a living

and i choose ck because it might be fun to hang out with a ghost *thinks of no-face*
