Well we know that Shin DXD 3 is Yasaka's volume, so I believe that the Ravel's can explain the supremancy's way of Ravel. About Ravel Ishibumi said in V.22 afterworld that she will play a important role in this arc, so I'm sure that she can help Issei to defeat Rias and Issei could learn from her to become a good leader and strategist. Aso I have hope that the Phenex's family will make test for Issei.
