What if like in the future Mizo and Kimiko get it on and they have a kid who develops a Rinnegan

It would either be a miracle of modern ninja science or I'm just glad that one of the girls is living her truth. 

Either way, that poor kid is screwed. I mean, one of their mother's would be a high-functioning alcoholic and the other a narcissistic ice queen. Throw in that busted doujutsu and possibly a horrific tragedy or two, and this kid's prime anime protagonist material.
