Pretty straightforward one but I think these tips could help:
. Queen of the Night is vulnerable to Light and Storm attacks, so use Aurora and Finn's magic attacks.
. I played on Normal mode and didn't have a lot of trouble defeating while on Levels 52 or 53 (no need for leveling up characters to maximum).
. As any other boss fight in the game, use Revive and the HP and MP potions, especially to recover Aurora and Finn or other characters you've added Light attacks on Oculi crafting. Besides that, use the Armor when the Queen is loitering and Defend when HP is low.
Hope these could help.
