I've been looking for Kaminoko since I found out the manga existed, and it's just nowhere. I even e-mailed Lilillicious to see if they'd send it to me, but I never got a reply. Unfortunately, I'm expecting the DVD serialization to be even more difficult to track down
And yes, chapter 3 explains a lot if you pay attention (especially why I don't like Arume
), and chapter four gets into a lot more depth on the impact the aliens have had on human society. Hopefully that chapter won't be far behind this one
