Okay, so here's the thing. Think about the "Apostle" rank as a bonus rank of sort that you can reach eventually. It is really not worth the effort to try and attain it. When Kornel put it in, I voiced out that it was a little too unfair to the player due to the circumstances required to even get one of these things, let alone kill it. So, just treat it like a bonus rank that you can get. It was, and is, never meant to be attainable as a part of normal game play, kind of like the God Hand rank for badge count.
