In her text (what I have seen) she has said that in her world her father had 2 sisters but when the machine failed it made another dimension witth just 1. Yandere chan. Maybe in the 2nd dimension Yandere chan and Fun girl are sisters and they're father messed up with the machine, making her being scattered across time and space. That's what I think at least. I could be wrong completly.

It doesn't say that the machine created the second universe. The way I interpret it is that the parallel universe had always existed, with one difference being the machine being invented in the parallel universe but not this one. Therefore in this universe he either only had one daughter to begin with, or the second daughter is still alive in this universe.

Regardless, I still believe that Fun Girl is Megami's sister, it fits better with her father being the CEO of Saiko, making him a probable "person who invented many things".
