I am aware that in Mystic Square Stage 4, if you fight Yuki or Mai for the second phase depends on who you deal more damage to.
However, this made a question pop into my head:
Who do you fight if you pacifist run the first stage of the boss fight? Is it randomised? Is it set? Do you skip the second phase altogether? [Doubt that] Or does the final pattern keep going until you *do* hit one of them?
