MAGES.
In Hyperdimension Neptunia Victory, it was revealed that 5pb. and MAGES. are related, but it wasn't revealed how they were related until Hyperdimension Neptunia Re;Birth3: V Generation, where they are revealed to be sisters, with 5pb. being the older sister, and MAGES. being the younger. This is similar to the relationship of the companies they are based on, with 5pb. being older than MAGES.
