Persona 5: Royal

Third Semester Palace:
To unlock the third semester events (exclusive to Persona 5: Royal), reach Rank 9 for the Councilor Arcana by November 17th. If you are Rank 9 with Takuto Maruki on November 17th, you will automatically reach Rank 10 and some major endgame events will begin, including a new path to an optional final boss battle. If you are not Rank 9 with the Councilor Arcana, you will not experience anything new and just get the standard Persona 5 endgame scenario. The Councilor Arcana belongs to Takuto Maruki. He is a new major character you can find in the school —- he appears in Shujin Academy after Kamoshida's Palace is complete. The School Counselor is a fast friend, and eager to understand the cognitive psience behind the Phantom Thief phenomenon. Leveling up the Councilor Arcana improves your ability to randomly remove status effects or recover SP when you are low. The higher your Confidant rank, the more you will be able to recover. However, it is still random.
