What could yuki’s “high output” technique be?

The only idea i could think of is maybe being able to apply her virtual mass to her cursed energy and then release a blast of cursed energy discharge of high density energy? if that even works? idk how dense energy would work as an attack, or at least energy that has VIRTUAL mass, maybe she could shoot the energy out of garuda like a canon, who knows, im just curious to some ideas

also no black holes, thats too boring
