Sons of demon

Simple genetic issues in newborns, like having six fingers and having two different eye colors, were the beginning of it all, but it developed to the point where we are now. There are many different types of monsters in the world today that were once in their mothers' wombs, but now they are only extremely dangerous creatures like water monsters, flying monsters, and night-living monsters. Pregnant women are treated as criminals, and society will punish them harshly because, in all of this chaos, one thing is certain: there will never be a normal child again. However, as time has gone on, some people now have genetic issues that are not severe enough to create monsters but not enough to qualify as humans.
