Well the other Cyborgs could just be not answering the call, whether because they're unwilling to give up a normal life or simply busy with other things we don't even need to know, this way you don't take up one of the nine slots in case other players come in and you can keep it a mystery whether the other cyborgs were already consumed. The story setup does say that usually they only gathered a few at a time and that there's been plenty of other threats across the years.
