This probably sounds dumb, you might be thinking "It's called sister location because it's the sister location to freddy fazbear's duh," but it's also named sister location because the plot is that you need to locate your sister (you play as michael afton trying to find elizabeth afton, your sister.)
Five Nights at Freddy's: Sister Location is an indie point-and-click survival horror game developed by Scott Cawthon, and the fifth installment of the Five Nights at Freddy's series.
Sister Location is called Sister Location because mike is who we play as and elizabeth his sister is circus baby and the name of the pizzaria is called "Circus Baby's Pizza World" so its called Sister Location is called Sister Location because elizabeth is mike's sister. Sure, but also the meaning of "sister location" is a business owned by the
