This run is an adjustment of my first run where instead of focusing on skipping the mechanics I allow the boss to turn warp at 79% in order to achieve a lower turn count of 2.
You'll be protected by Kam'lanaut's Paralysis anyway so the 1 boss turn doesn't matter.
Setup
Machina FR30 with 5/5 UW, Raines call. You can swap Machina with Tidus
Kain FR30 with 5/5 UW, Kurasame LDCA. There is no alternative for Kurasame call.
Lunafreya FR30 with 5/5 UW, DKC call. This call can be swapped with any call that lands HP damage up debuff.
Brothers summon
Kam'lanaut friend with FRBT

Reset until Luna goes first followed by Kain and Machina. Apply Heavy Prayer on Kain then spam S1 until she can Heavy Prayer Machina. Then use both DKC call. Then spam S1 until she is dry.
Use LD and this time what I do is focus all her free turns doing as much damage as possible, so either S2 or EX. Use S1 ONLY before using her next LD. Don't waste her Quick Prayer buff on S1.
Do BT+ when there are TWO LD skills remaining. There is no need to preserve BT aura so might as well use it earlier.
Once BT aura is up Heavy Prayer both Kain and Machina.
Once she is completely dry, swap her for Kam'lanaut, use AA and BT+
Kain does Kurasame base call, AA, BT+, LD, Kurasame LDCA and then jump.
Machina does LD then EX then BT+. Somewhere here boss will turn warp. Be sure to pop summon only after BT+.

Popping summon dispels purple aura on boss. Use the time to go Kam'lanaut FR into Machina Double Raines and LD
9:19 Machina BT Mode
Focus on boss except when boss uses Morph to cleanse debuffs, use LD on the Irvine Manikin then.
