Thanks Drac, actually I've seen the second 
OVA.  I was totally confused since I haven't 
seen the first one.  My brother kindly explained 
the whole OVA1 plot to me.  I haven't seen 
either of the TV series yet, maybe someday...  I 
also got a little sketch of a fly looking thing 
when i got my nightwalker cel.  Not sure what 
it is or where it's from though...
