Assuming you mean base GUR with 20,000 attack, and you're asking about the skill proc dealing 999,999 damage, 1x 300% buff can do it if you have about +120% in bonuses. Remember that she gives 50% herself, so you just need another 70% elsewhere (building bonuses, unit bonuses, another Hiraga, etc). This should be fairly easy to get.

With 1x 200% buff, you'd need a bit over 190% in bonuses. This will require 2 Hiraga and nearly every bonus including upgrade potion.
