As of Version 2.0, those who had 100% completion in the original game will now show these new statistics for their save files:

• Effects: 71%
  
• Collectibles: 93%
  
• Dreams: 85%

There are now four new Concept Art collectibles and two sketch pages.

This guide will help you find all of the Concept Art, one of the collectible types of Yumenikki -Dream Diary-. Completing your Dream Diary is one of the requirements to get a 100% completion and the Lucid Dreams achievement.

Every Concept Art has a detailed walkthrough with direct images of the locations. Naturally, this means this guide will be FULL OF SPOILERS. You have been warned.

There is also a chance that the actual order of the pages in your Dream Diary might be different from mine. I'm not exactly sure why this happens, but I guess it's determined by which places you visit first.

For the purpose of recognition, I will refer to most NPCs by their fan-given names on the Yume Nikki wikia[yumenikki.wikia.com].There is a total of 44 pages 50 pages in the Dream Diary. If you have less than that number, you're likely missing more Concept Art. A few of the pages will contain sketches. Fortunately, sketch pages will fill themselves up as you explore each world, encounter more NPCs and witness more events, so you don't have to worry about them too much.

Please feel free to make suggestions to this guide. If something isn't clear enough, please speak up.

Description: Poniko & Uboa sketches
Location: explore the Pier, Dark Forest and Pink Sea.

Page 4

Description: Pier/Forest sketches
Location: same as above.
Note: The Yuki-onna sketch at the upper-right corner is very easy to miss, as it only appears when you trigger a specific Easter egg. You don't need this sketch for the game to count your Dream Diary as 100% complete. But if you really want it, I recommend getting the Umbrella Effect first.

To get the sketch, you need to complete the lighthouse section of the Pier as fast as possible in one run. If you die once, you need to wake up and start the dream over. This is tricky, but doable. You can safely take cover behind the first two hiding spots you come across. But as soon as the lighthouse's beacon touches the second hiding spot, start moving immediately and try not to stop. If you manage to get to the next two hiding spots without stopping, you timed it correctly. Use the Umbrella to easily skip the platforms. Also use the Umbrella at the last stretch of the lighthouse section (the shallow water before you reach the Forest). Don't worry, the lighthouse's beacon won't kill you here. Continue through the Forest until you reach the igloo. Whatever you do, do NOT enter the Hamsa door next to Kimajo (tree monster). This will cause the Yuki-onna to despawn and you'll have to do the lighthouse section again.

When you reach the igloo, check the upper-right part of the screen for a spotlight with a figure standing in it. While it's hard to see due to being so far away (and it's snowing heavily...), that is the Yuki-onna. Seeing her will give you the Yuki-onna sketch for page 4.

Location: Complete the Sewer and Block World areas.

Page 30

Description: Block World/Snow World sketches (available as of version 2.0)
Location: Complete the Block World and Snow World areas.

Page 31

Description: Mafurako (available as of version 2.0)

Page 32

Description: The Black Cat (available as of version 2.0)
Location: Sewer. This one is a bit of a tricky find. Go to the southern section of the Sewer, where you will find a large pool next to a faceless ghost (Nopperabou Ghost) nearby. Search near the center of this pool. You won't see a white sparkle here.

Page 33

Description: Mouth Monster (available as of version 2.0)
Location: Wilderness. To access this Concept Art, you need the Hamsa, Scarf and Hat, and Umbrella Effects. Close to the picnic area, use the Hamsa to open a new area. This will lead you to a looping maze (anyone remember The Legend of Zelda for NES?) In the maze, move down, left, down, right. This will take you to a pond with murky water and a lone island. The Umbrella's double-jump is ineffective here. You need to equip the Scarf and Hat, then use the Umbrella's rain ability (which will now be a snow ability). The water will freeze over, giving you access to this Concept Art.

Page 34

Description: Snowman Madotsuki (available as of version 2.0)
Location: Snow World. This world is difficult to navigate since it loops infinitely like a classic Yume Nikki world. As soon as you enter this world from the Block World, take these paths: east, north, northeast. You will know you're at the correct place when you find an igloo further to the right. From the igloo, go north until you encounter more trees. From there, move further to the east. Eventually, you will see a bed obscured by the trees towards the north. The Concept Art will be sitting on top of the bed.

Page 37

Description: e-Man and o-Man
Location: Mall. Talk to the o-Man to get the Flute effect. Then, speak to the e-Man, who will play a tune for you. Play the same tune with the Flute and he will react (you may also hear what sounds like a shutter door opening). Speak to him again and he will give you the collectible. This interaction is a bit glitchy, so it might take a few tries.

Version 2.0 changed the method slightly. Talk to the o-Man to get the Flute effect. Talk to him a second time to get the Concept Art.

Note: For those having trouble reaching the 2nd floor due to a previously open door that is now locked, you must pull the lever on the 2nd floor to eliminate the metal bars to the right. You should now be able to reach the 2nd floor by jumping off the window and gliding with the Umbrella.

This item will also register as a collectible called ???.
