LTL thank you for putting that together and in doing so confirming the existence of the 'angel' video as it is often referred to, where Hana is wearing the same clothing as in the Jenny angel vid (06?), you have this named Hana-t04. For those looking, links with this name generally lead to the blue/yellow vid as alluded to by litanglvr.
Your preview of 'Hana and Naine (t01).avi' also jogged my memory as to the mention in the past of a 'bunny ears' vid, which i failed to include on my list, this is clearly that one.
In agreement with litanglvr these two videos are the ones that appear to remain in the hands of a select few collectors, so being a Hana fan i would politely request that when the time and the place is right you would put a priority on releasing these two into the wild, thanks.
I guess that's just about it for Hana for now, would anyone have either of the nn Xara vids to share?
(perhaps only for obsessive collectors... the attached lo-res pic is not included in set 31, this image featured on one of the public pages of her website.)
