First of all, something I'm going to be saying which involves my question is a spoiler for chapter 52 of the Owari no Seraph manga.

After the fight with the 10th Progenitor outside Ferid's mansion the squad are baffled at how a 13th Progenitor beat a 10th Progenitor. It is then revealed to us that Crowley Eusford was actually a 7th Progenitor becuase he was given the blood of a 2nd Progenitor. So that considered, why is Mikaela not a 8th or 9th Progenitor? It's stated int he Wiki that " a human turned into a vampire by a progenitor becomes a noble". If that is the case, why would Crowley Eusford be a Progenitor but not Mikaela?
