question: how strong is Vali compared to the current Rias and her peerage? the reason why I am using him as a reference to measure by is because even the early canon Vali was quite strong, being at least ultimate-class with his Balance Breaker
Rias and Akeno are stronger than him. If Gasper loved fighting, he would be crushing Vali. If Gasper didn't hate violence, it would be stronger with the fact he absorbed the remains of Balor. With Kiba, it depends on whether he's able to summon an appropriate sword quickly enough. Anyone else in her peerage would be crushed by Vali
