Rude & Elena EXTRA Section Battle Clear - FF7 Ever Crisis

This is how I cleared Rude & Elena EXTRA section boss battle in Final Fantasy VII Ever Crisis.
I feel the best strategy for this was to be very defensive! But here are some other tips.
- Make sure your healer has high healing potency and keep topping everyone off with Curaga or whatever AOE healing ability you're using
- Everyone in the party has around 7000-7500 HP for survivability
- Everyone has Circle Sigil Ruinra materia, not Ruinra Blow or else Rude will counter attack and most likely kill one of your characters
- Based on the best recommended materia and weapons the computer will probably have the rest of your setup good with Wind and Fire elemental attacks but it is extremely annoying you can't save a setup in case you fail the fight
A strong account is obviously needed to complete this fight as well.
