The sixth Palace of Persona 5 Royal belongs to Sae Nijima, the older sister of the Phantom Thief Makoto. Changing Sae's heart has been Makoto's goal for some time, but the reason the Thieves are focusing on Sae is that the law is closing in around them. With Sae on their side, Joker's band of thieves can focus on catching the true culprit of the mental shutdown cases, but first, Sae must see the error of her ways.
