are you retarded? we see TONS of examples of humans and umas reproducing, it's literally the only way umas can have babies. Every single uma musume with an uma mother has a human father.

There's even umas whose stories involve their uma parents and human fathers, plus they'r even featured in the anime and movies. Wtf are you talking about? Even trainer-uma couples where they get married after retirement and have uma babies are canon, that's literally Mr. CB's backstory. Her dad was her mom's trainer.
