Also since some of the leaders talked with Issei in Volume 22 and mentioned they needed supplies on occasion, I think Azazel could still help work on it. The fact they had time to talk with Issei implies not everyone fights Trihexa at once and they've gotta swap out so everyone can recover and replenish in a cycle.
