@Pawn, if Demonic Powers can't be increase then how do you explain Rias increasing her Demonic Powers? You're misunderstanding lack of talent for Demonic Powers as Demonic Power being unable to increase. Both Ise and Sairaorg have a lack of talent for Demonic Powers, it's not that their Demonic Power can't increase, they can but due to their low affinity with Demonic Powers, the increase is insignificant.
