Question

What is the name of the OST that plays during O & P cinematic battle scene (the scene I am referring to can be found here¹)? Any search results always leads me to the OST that plays while you are fighting them, not the OST that plays during this cutscene

We don't know most of the game's OST yet, but luckily I believe you picked one we do: The Weight of Life.
