Effect Get Characters
Two twins that serve as portals. The Black Beret Sister is located in the Dark Room's theatre and transports you to the Snowy Pipe Organ upon interaction, leading to her blue twin, who stands in the way of a door to reach Atlantis. The only way to get pass her is by using the Boy, Gakuran, or Wolf effect, or using the Chainsaw on her. Her beret will be left on the ground if chainsawed. Alternatively, interacting with the Blue Beret Sister will cause her to swap places with you, allowing you to pass. Interacting with the Black Beret Sister will grant Kura Puzzle #14.
Found at Elvis Masada's Place. If you interact with them, they'll play a lovely tune for you. If you try to harm them with the Chainsaw effect, they will sound very frightened by playing a mangle of notes on their piano. If you interact with them using the Trombone effect, they'll play a duet with you.
A boy found in the room under the stairs in Urotsuki's Dream Apartments. He reacts to many different effects. There is also a 1 in 31 chance that the he and his room will glitch up upon entering (it's reset everytime you enter the room) and his sprite turns into a mass of eyeballs. He is most likely the 2kki equivalent of Poniko. Seishonen reacts to the following effects:
- Boy - Follows you around and looks at you when he catches you.
- Rainbow - Causes him to jump;
- Fairy (when pressing action) and Penguin - Makes him look around;
- Glasses - Causes him to turn into a red-schemed girl and run away from you;
- Telephone (when pressing action) - Makes him look around fast;
- Invisible (when turned invisible) - Makes him look around for a few seconds before changing into the same red-schemed female seen when Glasses effect is used, only this time she does not run away;
- Child - Follows you around at a fast speed.
Odorika is an oriental-styled cyclops dancer located in Red Streetlight World, in the center of a large circle of streetlights. She is shown wearing a red oriental dress, with bandages covering where her eyes should be and a large third eye in the middle of her forehead. Two small white rabbits dance beside her under a lone streetlight.
Using the Maiko effect to bow in front of her triggers a full-screen event, in which you can see her dancing side-to-side with her two rabbits. Viewing this event will unlock wallpaper #20.
Odorika's dress can be worn by Urotsuki in the Dressing Room, by combining the maid outfit with the Stretch effect.
Found in the southernmost room in the Dark Room. Each time you enter, she is found either sitting in her chair and reading a book or standing up, looking at the books in her bookcase. The Telephone effect can be found here, thanks to her moving pet telephone. If you use it on her while she is reading, she'll leave her book on the chair and fly away. Interacting with the book takes you to the Art Gallery. If you chainsaw her and interact with the left side of her bookcase, you can look at a page in a book that features pictures of her.
She is visible from The Monster's Jaw by using the Telephone effect and looking off the edge. She and her telephone will be sleeping, and Oni Musume will have her book on her face while lying down on her couch.
Oni Musume also seems to strongly resemble Remilia Scarlet from Touhou Project in terms of appearance only with pigtails or with some sort of hair accessory in her hair (which could either be bows or hairclips going by the sprite). Her location and behaviour seems to be based on another Touhou character, Patchouli Knowledge.
Found sitting on a chair in the Dark Room, and turns his head if you use the Telephone effect. He can also be seen for a second time in the room to the left of Tapir-San's Place, sitting in a chair and sometimes watching a ghost of Urotsuki sleeping on the floor.
The Twintail Monster is an NPC that has existed since old versions of Yume 2kki, in which it used to give out the Twintails effect. It is hidden in the Broken Faces Area, nearby Marginal Vivid Worker and Surimuki. Using the Glasses or Twintails effects near them will make the Twintail Monster appear.
Kamen Eshi (alternatively named Painter-kun) is a character found through a painting in the Art Gallery, or through an area of the Red Brick Maze that you are sent to by interacting with one of the Shadow Ladies in the Day & Night Towers.
Kamen is usually found painting a large mural of something that looks like a road or a path. He has blonde hair and wears a multi-colored shirt/smock, a black dog-like mask and jeans. The only paint color that is seen on his brushes is red. He is busily painting and never seems to have enough time to talk to you.
If you try to interact with him while he isn't doing anything, he will simply look at you. If you kill him with the Chainsaw effect, his blood will be splattered over his art, and his mask will fall to the ground. This death is permanent, and he never will come back. Doing this unlocks Kura Puzzle #28.
They are found wearing a buttoned shirt with bandages around their head, hooked up to an IV with a green substance being fed through it. Aojiru reacts to nothing, and trying to interact with them will automatically make Urotsuki kill them with the Chainsaw, even if you haven't collected it.
Aojiru can also be seen sleeping in their hospital room when Urotsuki equips the Chainsaw and looks out of The Monster's Jaw.
Found behind the counter of The Underground Bar, he is visually similar to KyuuKyuu-kun from Yume Nikki. He is interactable and serves you drinks. Drinking too much unlocks an event, and buying at least one drink unlocks wallpaper #103.
All located in Japan Town, only two of the four are interactable. If you try to interact with the Wheel Girl and News Man, they disappear. You can go inside the Box Shop Keeper's shop by going through the wooden door and using the Glasses effect to find a hidden door near the pile of garbage. The Geisha Shop Keeper allows you to change the style of your menu, and if you sit with her she will begin laughing silently. The Geisha also bears a resemblance to Urotsuki when using the Maiko effect.
The submarine's crew, which can be found from The Docks. Both wear red, military-like uniforms, which is similar to Russian uniforms. The Commando wears a gas mask and does not talk nor respond if you interact with him. The Assistant, when on the submarine, will make the outer shell invisible so you may see if you are on the bottom of the sea or not. Provost-san's gender has yet to be determined (though a majority of the western fanbase proposes Provost-san is female, the Japanese fanbase proposes male), and their confirmed Japanese name is "Kenpei-san", aka "Provost" or "Military Police-san".
Smile-san is found in Flying Fish World. He is in the doorway that is boarded up so you need to chainsaw the boards to get in. If you use the Telephone effect on him, his laughs will be played overlapping one another at different speeds. Waking yourself up will cause one final laugh. Using the Rainbow effect will also shut him up.
A pink-haired girl in a spacesuit and helmet. Found in the moonlit balcony in Flying Fish World, on a block in Square-Square World, and her apartment annexed in Flying Fish World. She transports Urotsuki between the two areas. Interacting with her in her apartment while under the Spacesuit effect will teleport Urotsuki to Square-Square World. Likewise, interacting with her in Square-Square World while under the Spacesuit effect will teleport Urotsuki to her apartment.
Found in the Visine World, Megusuri Uri is a quite lonely eye doctor with four eyes covering his face, and two eyes on the back side of his head. Chainsawing both him and Hakoko can cause the shop to be locked upon leaving; they can be revived upon interacting with the boy NPC in the Bleak Future.
He is very similar to Midori Tokuro, considering the fact that they are both made by the same person and that there is a wallpaper featuring the two.
Found in the same area Megusuri Uri is found, she peers over the top of her box with her large blue eyes to stare at you before going back down. If you use the Fairy effect, she will reappear. Chainsawing both her and Megusuri Uri can cause the shop to be locked upon leaving; they can be revived upon interacting with the boy NPC in the Bleak Future.
A ghostly woman wearing a torn red dress found at the end of the pier at the Dream Beach. She will appear if you interact with the lamppost next to the fisherman and wave her hand if you interact with her, as if to say goodbye. Her name is based on her visual similarity to Sachiko Shinozaki from the game Corpse Party.
A fox-masked man in a colorful yukata that can be found in The Invisible Maze and The Baddies Bar (possibly implying that he's an enemy). If you move in the direction he's facing when you're in the black and white part of the maze it will lead you to the Invisible effect. If you try and chainsaw him, he'll leap behind you to avoid your slash. Sometimes, he'll attack you and send you to a closed off area, like a chaser, which could explain why he's in The Baddies Bar.
An octopus man located in Atlantis' city area. If you use the Fairy effect on him, he will become frightened and reveal his tentacles and large eye. Doing so will also unlock wallpapers #28, #241, and #330, as well as Kura Puzzle #16. By interacting with him from a direction opposite to the one he's facing, he will turn and look at you, and stare at you for a moment before continuing to walk around.
In the same style as the Clown Chasers, these three are located through the Underwater Amusement Park at the end of the area with black and teal tiles on the floor. When you reach them, the one playing the accordion (Anastasia) will take over the music and will play something similar to the popular VOCALOID song Dark Woods Circus. The one that is strutting about with their hair in a side ponytail has been fan-named Nikolai and the final one with pleated hair and balloons has been named Arina. Chainsawing one of them will not make them go insane like the Chasers, as they die as the same way other NPCs do.
A pregnant woman found in Urotsuki's Dream Apartments. The only effect that works on her is the Insect effect that makes the baby enlarge when used. And if you chainsaw her, there will be two screams instead of one, despite the baby being a fetus (as clearly seen).
Encountering her will unlock both wallpaper #23 and wallpaper #309.
A green-haired girl found in Cutlery World. She reacts to the Cake effect quite strongly when equipped. She will also follow Urotsuki if she equips the Boy effect, and walk away if she equips the Wolf effect.
A book containing what appear to be her last words is in the Library. Enter and go left to the last book in the first bookcase. You will be greeted by lined paper. Press enter and words will appear, she will pop up and giggle/sob. This note she has written says "すりむいちゃった。" meaning, "I got scraped." Surimuki's half-buried head can be found in Broken Faces Area.
Can be found in the area to the far southeast of the Highway. The smaller one has been called Desu-chan due to her large eyes and hyperactivity. She will move away from you if you equip the Chainsaw, and look around if you use the Fairy effect. Her sister, Onee-chan, can be found either sitting on a bench on the pier or standing near Desu-chan. She will turn away from you if you interact with her and if you equip the Chainsaw. Interacting with one of them will unlock wallpaper #10. However, if Desu-chan is inside the TV Room you will not get the wallpaper by interacting with Onee-chan.
Located in the exterior of the Apartments, Hiboushi is a woman who appears to be sitting. If you interact with her, a close up picture of her face will flash up on the screen, before she vanishes. She is the Yume 2kki equivalent of Monoe. Also, she strikes a very similar appearence to Nichiyo-san.
In a previous version, Hiboushi was replaced by an NPC with identical function, nicknamed "Lamp Post Boy".
A boy found in the top right room of the main Apartments. No effects work on him except for the Glasses effect, which causes his body to disappear but his glasses remain floating. If the UFO is in the Apartments area, he and his bunny will be scared, and running.
A sobbing girl in a pink skirt and purple top, found in a tunnel in the Stone Maze. If you interact with her using any existing effect, she will sob into her hands. When interacting with her, there might be a random chance that it will cause her to act as if she were killed, and she will fade away.
Found on the way to get the Stretch effect. She is not interactable and you cannot get near her. She simply swings there, bleeding onto the floor.
A lady in a large sun hat that is found in the Pastel Blue House standing under the red sun. If you try to chainsaw her out of the way, the sun's eye will glow and de-equip the effect.
She can also be found on the way to Urotsuki's Dream Scene, usually seen sitting on a bench in the background facing away from you. Rarely, she can be seen here in her sprite form, and will be much more noticeable. She seems unamused and doesn't react to anything, no matter what effect is used.
She bears a similar appearance to Hiboushi.
Found at the Sewers' entrance to Japan Town, he is a man in a suit with a sign for a head. He does not respond to anything. On the sprite sheet there is a sprite of him facing the other direction, If you interact with him, he will play a honking sound, similar to that of a horn.
Found in the easternmost area of the Blue Forest. No matter which effect you use when interacting with him, he will only shake his head. If you sit next to him, he will keep looking at you.
Found in the same area as the Boy on the Bench in the Blue Forest. If he is not on the bench, Hebiko can be found in a small clearing toward the lower right. If you interact with her, she will open her mouth wide, stick her tongue out, and make a loud giggling noise.
Can be found watering plants in the Farm World. When interacted, he tells you via a speech bubble what kind of plant he is caring for at the moment, which is always a picture of either a chili pepper, a slice of pizza, or a Japanese maple leaf.
A robot found in a small room inside the Dark Alleys. He holds a monitor with a display that changes depending on what effect you are wearing. On the screen it's possible to see static, an eye that watches Urotsuki, a spinning triangle, a sine wave, and bubbles.
Note that sometimes there is nothing on the monitor (he will either be looking around or just holding it by his side). What's on his monitor also changes the sound he makes.
A violet amoeba located in Urotsuki's Dream Apartments. There is a 1/6 chance of a tree to appear in its home, which takes you to the Flight event. Apartment Amoeba reacts to the following effects:
- Fairy (when pressing action) - Spins around;
- Telephone (when pressing action) - Shatters like in the 3rd sprite;
- Stretch - Becomes the 2nd state in the above picture;
- Boy - Changes to look like Urotsuki;
- Marginal - Becomes transparent and dramatically increases move speed of the blob.
A small one-eyed creature who sits on a couch in between the Gray Road and Grass World. He is usually awake but is sometimes seen sleeping. Equipping the Chainsaw effect while he's awake will cause him to look down nervously. He will occasionally blink if you use the Rainbow effect's flash, although it is very hard to see, considering that he blinks when the flash is just fading.
Akama is a witch located in Jigsaw Puzzle World, who blocks Urotsuki's progress with a small minigame. She is shown to be blonde with purple skin, and wears dark red robes with a large witch hat with a depressed-looking face on it.
In order to get past her you need to walk around the area and make blocks appear, and then collect the large colored orbs that also appear. After collecting enough orbs Akama will fade away and you can enter the area behind her, which houses a large mirror. Interacting with it shows you a more detailed picture of her, then a picture of Urotsuki.
A blonde-haired bat girl that resides in the Apple House of the Fairy Tale Woods. She is normally seen walking around in her house, sometimes sitting on the chair. She reacts to a few effects, equipping the Bat effect will make her follow you and she will spin once interacted. If Komorin has been killed, she will be seen crying.
Huyure-chan is found in the underwater area between the School and the Dream Beach. She lacks limbs, arms and hands and wears a jacket and goggles. She appears to be somewhat transparent, and if the Glasses effect is used, she will suddenly appear more clearly and will frantically walk around. If the Invisible effect is used, her face and body will become completely clear.
A large, detailed picture of her can also be found in her sprite sheet.
A dog-faced creature that appears to be based on Yume Nikki's Uboa. Located in the Sky Kingdom, there is a ledge with a small sign with Dogboa's face on it. Moving to the far right of the ledge will show a small platform with Dogboa frantically moving on it, in and out of view. It does not react to any effects.
Dogboa's face appears to be based on the Japanese kanji for sky, "空" (sora).
A strange creature with a faucet for a head found in the far left room in the Boogie Street. He can either be seen sitting in the inaccessible pool at the end of the room or standing next to the fountain. He doesn't react to any effects, not even the Chainsaw, and when interacted with he only makes a water dripping sound. He bears a slight resemblance to the NASU character from the original game.
An angel that lives in the room of Fountain World. They react to a few effects, such as Glasses, Chainsaw, Marginal, Plaster Cast and Child. The Glasses effect will reveal that the priest is some type of angel. Doing this unlocks wallpaper #167. Killing the priest will unlock Kura Puzzle #48.
An NPC found in the Monochrome GB World, he rests aside in a house with a patio. The only effect he reacts to is the Glasses effect, you can't kill him either. He bears a striking resemblance to The Batter from OFF.
A nurse found in the Underground TV Complex, she sits in front of a table looking around. When you equip the Plaster Cast effect she will follow you and "heal" you when she touches you.
A boy and a girl sitting on a couch in the Underground TV Complex, if you interact with them they look down at you. They appear to be blushing. Equipping the Chainsaw effect will make them shut their eyes. Killing one with the Chainsaw will make the others face cloud and they will begin to cry.
The owner of the Mask Shop, she is either napping or doing something behind her desk, she comes up to serve you when you interact with her. You can annoy her by ringing the bell constantly and leaving without even buying anything. But beware, consequences will be put in place.
The white maiden is a black-haired woman in a white dress, found inside the house at the Dream Beach. If the Child effect is equipped near her, she will run out of the house and down to the end of the beach, disappearing with a laugh.
A mysterious silver-haired maid who appears in various locations throughout the dream world (after wallpaper #107 has been unlocked).
When interacted with for the first time, she will give Urotsuki 500夢, and reveals her "true" face if the Glasses or the Eyeball Bomb effects are equipped nearby.
Equipping the Stretch effect will make her turn invisible, and she will turn away from Urotsuki upon interaction while the Boy, Cake or Gakuran effects are equipped. Additionally, she will refuse to look at Urotsuki at all if the Marginal, Grave or Polygon effects are equipped.
An NPC encountered in GALAXY Town. Normally, she just wanders around the area, but she can be considered a chaser in a very similar way that Yukata can; if Urotsuki attempts to take her life, she will pull out a chainsaw of her own (in stylish hot pink!) and attack back, banishing Urotsuki to an empty black void. Doing this will unlock Kura Puzzle #49.
She will follow around Urotsuki if the Boy effect is equipped.
A black and green lady with an eye that appears in each room of the Dressing Room. She reacts to a number of effects, such as the Wolf, Boy, Telephone and more. She will prevent you from leaving if one is attempting to go through the back curtains that leads to Fabric World, unless she is killed. Her death is permanent.
She is very similar to Megusuri Uri, considering the fact that they are both made by the same person and that there is a wallpaper featuring the two.
Found in the Tesla Garden's Industrial Waterfront, Noah is a cyborg boy sitting in a bench in one of the area's platforms. He will also appear in the Spaceship if the Industrial Waterfront has been visited before.
A dancing girl in the park section of the Graffiti City. She will dance quicker if the Chainsaw effect is equipped.
A rainbow-marked creature found in one of the Graffiti City's dead ends.
A tall pink creature who resides in the pink clothes shop of Graffiti City, and offers beverages when interacted with. She gives out a joyful expression if the Maiko, Twintails, Red Riding Hood, or Bunny Ears effect is equipped.
She can also be found a prison cell in the castle interior of Fantasy Isle only if Urotsuki has been caught by the guards when the Chainsaw is equipped.
Tokage (from Japanese とかげ, "lizard") are the main NPCs found within the Evergreen Woods. There are six of them scattered throughout the forest, each with distinct color schemes. They are likely designed to be references to the Namekuji of the original Yume Nikki's Forest World.
A young man found in Snowy Forest, near what appears to be his own tent and car. He is only alive while the forest is still in nighttime, as he will be found hanging if the player arrives at dawn.
Victim reacts to two effects; Telephone and Chainsaw. Using the Telephone effect will have him use Urotsuki's phone and then be rescued. Using the Chainsaw effect will have him fall over, and bleed over the snow.
An elusive NPC found on the cliffs in Snowy Forest. She only appears when no effects are equipped, and disappears if you try to interact with her. Interacting with her will cause the sun to rise and flowers on the cliff to bloom.
An NPC who dwells in one of the houses of the Sea of Clouds. He normally dons a sad expression. However, using the Wolf or Fairy effects will turn his frown upside-down. Interacting with him unlocks wallpaper #213.
A humanoid nine-tailed fox NPC found in the Fantasy Library and Red Lily Lake. Cutting off all their tails while in the Red Lily Lake will cause them to take Urotsuki to the Red Sky Cliff. If the Chainsaw effect is equipped near them in the Fantasy Library, it will be unequipped.
A cutesy character found in both Sugar World and Cutlery World. She can't be killed with the Chainsaw, but she can still bleed (perhaps it's jam?). Equipping the Child effect near her will cause one of her eyes to focus on Urotsuki while the other looks at the ground.
A doll-looking girl with a key on her head that perpetually rotates, found in Cotton Candy Haven. Using the Boy or Chainsaw effects, Urotsuki can take the key from her. This is necessary to access the Infinite Library.
Taking off the key will unlock wallpaper #270.
The Zodiacs are twelve different NPCs who all take residence in Constellation World. Aquarius, Libra, and Sagittarius cannot be killed, Aries, Capricorn, Gemini, Pisces, and Virgo can be killed, Scorpio and Cancer will hurt you when trying to kill them, and Leo will roar while Urotsuki backs away.
A conical green creature that wanders around near the sculpture room of Graveyard World. It slowly moves about with a dopey expression on its face. Wielding the Chainsaw effect will cause it to freak out, zipping about at high speeds. Chainsawing Hagure-Uzasu has a 1/3 chance of giving you 5000夢.
Red, bloody babies who crawl around the Train Tracks and the Closet Pinwheel Path. Interacting with them causes them to cry and make a face of disgust.
The titular inhabitant of the Parasite Laboratory. It can do nothing to Urotsuki. However, if she uses the Chainsaw on its container, it escapes and converts the whole facility into a living organism.
The presumed owner of the Monkey Mansion. He lounges on his throne. Interestingly, as the rest of the mansion has parallels to Urotsuki's Dream Apartments, the Marquis' room is directly where Urotsuki's room would be.
These creatures roam around the Cyber Maze. Each one takes the player to a different world. The angel takes Urotsuki to GALAXY Town, the bat to the Exhibition, the bear to Smiling Trees World, the flower to an extended path that takes you to either Dream Mexico or the Cocktail Lounge, the heart to Valentine Land, the sea lily to Sea Lily World and the purple-pink geometric figure to the Oriental Pub. There are also 2 currently unused NPCs. One is a hexagonal NPC that would take Urotsuki to the Dark Museum, and another that would take you to the Dream Bank.
The main event of the Maiden Outlook area. She will react differently depending on what time it is when Urotsuki visits. If it is daytime, sunset, or evening, her head will shoot off her body, landing near the cliffside Urotsuki is standing on. If it is nighttime, however, her head will already have left her body, and will be flying around like a hot air balloon above the town below.
The ever-running inhabitants of the Bowling Zone. The Bōringu Otoko are running bowling balls, while the Pingai are the running bowling pins. The Bōringu Otoko in The Lanes portion of Bowling Zone will send Urotsuki back to the start to the lanes if she comes into contact with them. The Bōringu Otoko and Pingai of Bowling Pin World are harmless, and won't even run from the Chainsaw effect.
A blue t-shirt creature with red eyes that can be found at the end of the Arrow Maze. They grant Kura Puzzle #43 and wallpaper #124 upon interaction.
The cute, fluffy inhabitants (whose name translates to "worrying endlessly") of Marijuana Goddess World. They jump when interacted with. They are unique in the fact that they can be set on fire by the Lantern effect.
The tall sea sponge of Atlantis. He blushes when Urotsuki wears the Wolf or Penguin effects around him, which unlocks wallpaper #195, and has a scared expression when the Chainsaw is equipped near him. If attacked with the Chainsaw, his eyes will turn white, and his mouth will leak blood. The Seanut will also react to other effects, such as Gakuran, Boy, Marginal, and Bunny Ears. Like Painter-kun, Seanut will not come back after he is killed.
