Warning: Today is the final day that you can steal the heart of Kamoshida and if you don't, then it is game over.
Despite it being Sunday, there is no shopping TV show today. If you haven't done so yet, go to the Flower Shop in Underground Mall to purchase a Bio Nutrients. Also, you can use this time to look at the wares at Untouchable, provided you have some money. Armor is more important than weapons, should you be only able to afford a few things, but make sure you leave yourself some extra money for some activities. When you're done, go to the drink shop in the Underground Walkway to purchase the Vitality Aojiru (5,000 yen) to get a point in Proficiency.
With that done, go to Central Street and visit the Diner, opting to purchase the Hot Coffee for 700 yen, which will increase your Guts by one point and Knowledge by two points. During the evening time slot, head to the Bathhouse to get a two point increase in Charm.
Today's the big day to learn whether you are expelled or not. There are quite a number of scenes here, so sit back and enjoy them, answering whatever when questions are asked of you.
Castle of Lust Falls
Complete the Castle Palace.
When everything is said and done, you will need to find a buyer for the medal you received after finishing up Kamoshida's Palace. You don't need to worry about that right now, so when the conversations are finished, you'll be back at Leblanc in the evening. There's not much you can do at home, so take another dip in the Bathhouse to gain another three Charm points, since it is Monday and all.
You can't do anything on the 3rd, since Sojiro takes up all of your time. On the 4th, though, you break free of Sojiro's grasp and need to head to Untouchable in Shibuya. You end up receiving 30,000 yen for the medal, and the clerk also hands over a Paper Bag as some stuff goes down. When you exit the store, you have the option to look in the bag, although both will lead to that outcome. There's nothing you can do in the evening, so go to bed and get ready to celebrate.
There is a lengthy cutscene here to start off the day, where you will celebrate with the others at a fancy hotel. When you finally gain control, you'll need to go to various tables, starting with the fish one, which is the light blue. You overhear some chatter and then will need to move onto other tables, mainly the rice, meat and dessert ones. After plenty more conversation, you decide to continue being phantom thieves and will have to decide on a team name. In the future interrogation, you learn of your next target.
Phantom Thieves Formed
Form the Phantom Thieves.
Unfortunately, that 30,000 you got for the medal has been reduced to a mere 6,000 yen after your little party celebration at the hotel, which is now yours to keep. Back in your room, feed some of the delicious Bio Nutrients to the plant, earning you another two points in Kindness. Go to bed to be visited by Igor in your sleep, with your Fool Confidant gaining another level, as well as your Persona stock increasing to 8 slots now. You can now have up to eight different Personas on your character, which is extremely useful.
