Not the "Ise is weak" guy, just letting everyone know.

They never said Ise had a threesome with Koneko and Kuroka (at least I don't think so). My guess is because of their connection, their pregnancy due dates were synchronized and it resulted in Shira and Kuro (that's what I call them sometimes) being born on the exact date and time....just throwing my two cents in there.
