Hello! I wonder if you're still open for the review, but here's my review regarding your first 5 chapters. What I write is suggestions which heavily I experience from reading, and may contain biases (my preferences). Feel free to ignore those that does not align with your preferences.
1) The typing. @miyaskya has covered most, and since English is not my first language, I have not much comment regarding wording.
Addition from me: In chapter 2, There's this sentence: "Hilargi heard the automatic door shhk open." Is shhk a sfx or is it merely a typo?
I also noticed that you put italic for Nikodemus' internal thoughts. In chapter 1, there's this part:
I have to think about humanity. Nikodemus convinced himself. Even if I'm always a captive, it's for the best. I'm the last hope for preserving the human race, after all. Nikodemus convinced himself.
There's double 'Nikodemus convinced himself'. I think the first one should be deleted.
Also in chapter 3,
I suppose I'll have to let that dream go, too. Nikodemus sat up, and, desiring to have some independence in his life, he said to the robot, "Hey. Put me down. I have two legs."
I think you can break the part from Nikodemus sat up into new paragraph. Again, this is just aesthetic-wise, in my opinion. Feel free to ignore if that does not suit you.
2) About Christianity, I wonder if this is actually has significance in later chapter. It would be interesting if it has. I don't know about rules in your place, but be careful when putting in religion based things into your story, especially if referenced from a real one. If you got this one covered, just do it then! Would love to see the progress.
3) While the idea is interesting, I don't get why the women wants Nikodemus that bad, for other than mating. Are there no man other than him, even from other species? Considering timeline and without explanation, it is a bit weird if he is also truly the last male. Human lifespan is not that long, and considering that there are many tribes, it would be more plausible in numbers if there are other males other than him. But, this contradicts the emphasizing why the women want to capture him. A bit explanation might abe to solve this
Other than the suggestions and question, I want to say good job! Your story has good world building, the words flow well, and easy to understand even by a non-native like me. Your characters have a lot of potential. Yair has been my favorite so far while Hilargi is the second because she is the creator of the lovely Yair. How the nymphs act also kind of realistic for me (you know, those bosses who don't care about bits of details, wants fast and tangible results). I rarely get hooked by a futuristic fantasy (to be honest, robots are not really my thing), yet I got hooked by your story strongly. When I have the time, I'll be sure to read yours!
