In the V.11 Shalba have used the bees for figth Issei, but Issei have destroys him... However I believe that only the most old maou's discendent was able the full power of the ability's bloodline, also we should consider that sometimes the genetic inheritance can be unpredictable( Sairoarg and Rias are the maximum example), maybe Katerea was not born with the eredetary power of Leviathan but perhaps with the ability of the other family... You understand what I tell you?
