So glasses guy was Risa... i remember hearing this name in chapter 3 without having any idea who he meant @_@ good thing i didn't try to search the internet just to get spoiled like the needle incident... R07 is such a hack for writing this and revealing it after 4 chapter even though it doesn't really matter... unless... he is called Risa because their objective is to protect Rika?... or because they want to have her... @_@
