@B214 most likely due to her upbringing, Rias and Sirzech,a pure-blood devil from noble family, are expected to succeed their father's position as a head of Gremory Clan, and stand above other devils. it's very natural for them to received a first rate education and training in leadership from a young age. Combining with their loving nature and talent, no wonder why they become such a good leader, especially when we compare Rias and Sirzech to other arrogant high-class devils.
