Eight down.
Well actually it was ten enemies. But it was also nine battles total. Hmm.
Dark Mindy and Dark Sandy then Dark Mindy.

That running away minigame is stressful, not in a bad way though. I don't know if any of them can hit multiple targets outside of mega-graviton. They have spells, so maybe they had ultima and just didn't use it, couldn't say.
Seemed like once you have it down to a 3 vs 2, all you need to do is keep auto-life active and keep their overdrive meters out of sync so they can't do too much burst damage.

Something else nice is they don't just immediately obliterate aeons, I was able to summon Anima with no meter, survive a mega-graviton and passado then land an overdrive.
The Dark Cindy fight had something funny to it. I summoned my own Magus Sisters and they actually really held out. Razzia and passado do damage, all three had auto-life cast on them and their speeds were pretty even.
