just to clarify, sorry for being insistent, Nier is full of androids with a desire to serve humanity, that is, Waifus!!, but it is also infested with cursed magic from the gods that generates one of two things, the curse of the eyes red (which let's say is the least harmful) and the most common curse, called by the humans of Nier as white chlorination syndrome (WCS) the gods give you two options, join our legion of monsters or die (not exactly but it is bad)
for the first question: No i dont care about alien s*x, as long as mc's human girls dont get pregnant with his alien from im good, for example i wouldnt care if looma get pregnant of mc's for arms form but i wont like if summer gets pregnant in that from, For the Second question: No i dont care if mc have a son, actually it would be good for character development, so go ahead
