As the title says, this is the final episode you can unlock. It is recommended you play or watch through episodes 1-5 of DRS before watching this video.

I've seen a few people get stuck at this part, so I'm uploading this to potentially help give an idea of how to be best prepared if you reach this part of the game. Beware reading below this as there are spoilers.

Before even starting the final episode, make sure you have done EVERYTHING you want to. This includes pulling from the school store gachas, grinding in the Vs. Tower and developing any characters you want to play as. Once you start the final episode, all of these modes will become disabled due to story reasons.

Personally, I don't believe you need to worry about getting all the hype cards for Makoto Naegi, however, I did manage to pull them and they do help. Additionally, I do think you should have at least 1 party of 4 characters built out and capable of reaching at least floor 100 in the Vs. Tower mode. Make sure they also have all equipped items, skills and whatever else you want. If you fail to have a strong enough party, you can potentially get softlocked in the game and not be able to beat it, forcing you to delete your save and start over.

The best way to build out a strong party is to have all 4 characters be of U rarity and have their WR card unlocked for them too. This allows their stats to go beyond 255 which is the most important thing you want when developing them. As for item grinding, I have found the "Ultimate" items are great as they both boost a single stat and all other stats slightly as well. Grinding floor 88 should get you materials to make the ultimate uniform, hat, shoes and talisman.
