Assuming that my (and many other people's) assumption is correct (that fun girl is Megami's sister) then yes she is also the daughter of Saiko's CEO, however note the subtle differences since we're talking about a parallel universe -

1. Only the parallel universe's Megami'd ever had a sister. This universe's Megami has always been a single child.

2. The father, CEO of Saiko corp, invented many things - the same things in both universes, however in the parallel universe he had one more invention than in this universe, which apparently caused fun girl to be caught in the limbo where she is now.
