Damn, that was nice
Got any more of that OP?
Did you just read the saddest hentai in the world too?
They haven't said what she is in either the anime, manga, or LN.
Her earliest memory was being in a dark, timeless void before the universe existed. But it's arguable whether or not that could be considered "her", because she didn't have a physical form or normal thinking until the time of humans.
No, but non-shitty raws are out for it(http://kikithedeceiver.tumblr.com/post/133987961805) and the translator says they can start doing stuff again. http://tateyamaa.tumblr.com/
Now it is only the feeling of lust.
They unfortunately never cover what sex between them was like or whether Azami was surprised about being able to be impregnated by a human. And there will never be any doujins for this series.
cuz he's a literal chink who writes in chinkese
