User blog comment:Mizuhara Yukie/Do you guys think that Mizukawa Minori and Potomuri is actaully ONE person?/@comment-5622730-20130730080419/@comment-5980423-20130803182732

I also believe that Kuroiwa is Kageyama.I mean...really now...same looks,Kidou speech at the end of episode 1...he said he was revived(he said it on CS game).So maybe he died in season 3 and got revived.
