"Demogorgon" Akashi boss fight - Persona 5 The Phantom X [GLOBAL] #p5xen

I found Skull's "God Hand Burst" for damage, Soy's "Smash Hit" for keeping the enemy's defense lowered, Tempest Riko's damage buffs, and Puppet's "Tide of Dreams" water shields to be vital for defeating this boss with the party I'd used. ETA: Utilizing the Highlights would have made the fight go faster, too. However, at the time, I hadn't figured out how to use them with my keyboard & mouse setup.
