Stygian Onslaught Luna VIII | Mavuika VS Configuration Device

C0R1 Mavuika / C6 Ororon / C3 Iansan / C3 Chevreuse. Full character builds here: https://imgur.com/a/jPCaIh6 The Nightsoul stalling at the start of the fight is silly and I didn't like it. But the gauge filled fast enough, and then I did some weird C1D Mavuika combo on a loop until it was time to refresh buffs. This boss takes a lot of self damage when the pillars are destroyed, and that's what made this feel fast and effective. I'm positive a different team with Xilonen or Citlali would also work even better than this.
