PDP Shard of Dreams Postgame Guide: The End

If you haven't already, Gap to the Human Village. Talk to Kosuzu and make sure you get her to read all the books you have. Any ones that have something in parenthesis means that you haven't read that one yet, so make sure every book has nothing in parenthesis.

You should have 9 Books. If you don't, then I would highly advise running to Scarlet Devil Mansion's library really quick and talking to Koakuma, since that's the only one you can really miss.

Upon reading the final book, a Yukari Puppet will run in and then leave. Exit the building to see the real Yukari waiting outside. She will give you the 10th and final book. Go back inside and read the final book with Kosuzu. She'll give you something, but I have no idea what it is.

Now then, save, heal, and Gap to Hakurei Shrine.

Do you remember where you first met your Starter Puppet near the Shrine? Head back over there. The Yukari Puppet will guide you a bit once you're going the right way. Go down the steps to the sandy area and talk to the real Yukari. She'll ask you a question. I don't know what the possible answers say, but it doesn't appear to matter. She'll leave and seem satisfied regardless.

Hop into the water to the right and surf to the right until you see a cave in the water. Enter it. Reimu will fight you here with a level 75 AyaP, level 78 YukariD, level 80 Reimu EX, level 75 SuikaD, and a level 75 Kasen EX. Continue past her and you'll see Kurumi guarding a teleporter. She will fight you with a level 72 ElisS, level 72 FlandreS, and a level 72 Kurumi EX. Enter the teleporter behind her when you're done.

This brings you to a rather pretty flower field. Go up to an area with bricks and weird glass-ish platforms. Continue along. There will be grass containing Kurumi, Elly, and Yuuka, all around level 71. Continue along, moving upwards.

Elly will be waiting near the door to a large manor. She will fight you with a level 72 SakuyaP, level 72 IchirinD, and a level 72 EllyP. Enter the manor behind her when you're done.

Before going up the central stairs, there's a couple things to find. Go to the right and through the little door. In here, go to the right into the little alcove with two doors. Through the upper door is a room with a bed to heal and a Yin Yang Orb containing a Sun Fruit Jam.

Head back out to the main room and go up the central staircase. Yuuka is up here and will fight you with a level 80 Kurumi EX, level 83 YuukaP, and a level 80 EllyP.

After defeating Yuuka, go to the left and through the little door. Go up and through the door in here. There's a Yin Yang Orb on the table here containing an item that I don't know the name of. Exit the room and go right slightly before going down and through a door. There's a Yin Yang Orb on the table here containing another new item that I don't know the name of (yay?). Exit the room with the door on the right. Go up and through one last door. There's another Yin Yang Orb here containing an Ecstasy Set.

Exit the room and go down the hallway and through the door at the end. Back in the main room, go back down the central staircase and then go left and through the little door down here. Go up and right until you see the double doors in the center of this area. Go through them.

Save. Save. Save. Save. Save. Save. Please save.

Continue up the path. The very long path. Seriously, if you didn't save, then save.

Mugetsu and Gengetsu are waiting at the end. Their fight is, as far as I can tell, the absolute most difficult fight in this game. So bring your absolute best Puppets and strategies, and good luck!

They use a level 83 KoishiA, level 90 Mugetsu EX, level 90 GengetsuS, level 83 Flandre EX, level 85 Satori EX, and a level 85 RemiliaP.

The Mugetsu will heavily burn you and constantly heal its HP. Everything else hits hard. You need to have speed higher than that of the Gengetsu in order to beat it, because it will one-shot most anything else. This means you need to check the wiki for Puppets with at least a Speed stat of 130 and then fully max the EVs for it and preferably give it a Green Mark.
Due to the fact that my strategy with the Gengetsu was just to one-shot before it could hit me, I don't know what moves she has. I'm sure that it's possible to survive a hit by her depending on what attack she uses.

To give an idea of the sort of Puppets you'll need for this, my team was as follows (please not that they are all reincarnated to have all S ranks, and you'll need a lot of type coverage).
Level 100 Koishi EX with red mark.
Level 100 ShouP with  black mark.
Level 100 Miko EX with a black mark.
Level 100 Futo EX with a green mark.
Level 100 MomijiS with a red mark.
Level 100 JunkoS with a black mark.

Upon defeating them, first of all, congratulations, and second of all you now have access to the New Game + feature and if you chose to import your original PDP file then you also will now have access to all your previous Puppets.

Just because you've completed the ultimate fight in the game doesn't mean you're done though! There's still plenty of things to do, such as explore the ice cave in the center of Misty Lake, visit Hecatia in her realm, fight Komachi and Eiki, or challenge the Makai 5 again. I'll go over these another time, but for now, I'm going to go start a New Game + and go over how that works in the next section.

Thank you for sticking around for this guide! :)
