Greek made an avi of him and named it after Hanma...

probably an assumption but since this Nikolay is the adoptive father of and "taught" Nemesis, I'm assuming he really is Hanma. He learned magic from Ma, probably taught Nemesis to be a demon beast master (is that the term used?) and maybe how to do whatever she did to the guns in the first chapter of the novel among other things...
