@Striker10 -- Koneko's original name, Shirone [白音] means "White Sound" not "White Snow".

@Anon3 -- Until we get confirmation, we can't say who their mother(s) are. Although odds are that they are the children of Koneko and Kuroka, there is a very slim possibility that they could be both from the same mother. And then there's the question of which is the child of whom. It would be a slight twist if it turned out that the "white" one was Kuroka's child and the "black" one was Koneko's.... Well, those are just my thoughts on the matter.
