I was always thinking that they are in the same realm of power but after watching the flashback of the family heads where its said that zahard and V are carrying them, i feel like the gab is bigger then i imagined zahard can prob take out 3 yurrin hon khun 2 weaker ones
I think after baam defeats zahard the higher floors open up and there will be more irregulars who climbed prior to the greath familys heads and he will find someone there
