I like the story so far but I have a few complaints I feel like you didnāt give enough time for him to develop, especially with the nature of his abilities Also the fact that the children will be birthed and grow so quick is just weird, at least give them a bit of time as kids, idk the powers seem a little too crazy and I fear that everything will be very rushed
Make some kids, save some money and go to a small country beyond the land of the samurai. In this type of area, people of the jounin level are gods, and there will hardly be many. Use the kids to dominate a small place, let history take its course, naruto and sasuke save the day while you farm. 20+ years later you'll probably have a bunch of strong kids to rule the world = GG
This is basically Pokemon breeding system except you are one of the parents. Since he seems to be treating women as a tool to breed and doesn't seem to intend to get any stronger or learn any skills besides the ones handed to him on a platter. Since the talent depends only on the mother, he'll order his harem around like pokemon and hide behind his barriers
