Yume Nikki Wiki

A sheet showing of all of Yume Nikki's characters

Madotsuki meets many characters in her dreams, ranging from "ordinary" humans and animals to bizarre monstrous creatures. Regardless of their appearance, none mean harm if one does neither.

The strange behaviour and expressions of the characters in Yume Nikki seem to exhibit certain personality traits. They influence a lot of the atmosphere of the game, even if they don't actually do much at all.

Many characters play a particular role in the game. Some give Madotsuki effects when she interacts with them whereas others may teleport her to different locations. Others may ignore Madotsuki completely and simply loiter in the world of her dreams.

Note: Certain characters, such as Madotsuki, Monoe, and Monoko, have official names. There are a few other minor characters who have their official names listed on their respective pages. A full list of these can be found here. All other dream characters were named by the fan community (see talk page).

Player Characters

There are only two characters that the player controls in the game, only one of which actually is real.

The titular, fluorescent inhabitants of Shield-Folk World. They appear to be inanimate and come in various appearances, just like the Neon Statues.

The Thing with the Quivering Jaw

Yn char quiverjaw.png
A gigantic, strange creature found in the White Desert B near a few weird structures. Its jaw quivers and makes a rattling sound, which can be stopped with the Stoplight.


Yn char UFO.png
Strange, flickering objects seen a number of times in the game. They can be witnessed in the sky of the Sky Garden's edge and on the Martian Summit, where they can be spawned by using the Cat effect.

Scrapped Characters

These characters either appeared in an older version and were removed, were reimagined in some way, or flat out did not appear in the game at all due to being discarded. An unfinished minigame also featured a scrapped severed head character, and the Submarine Fish has an unused variation.

Neon Statues

These characters don't do anything but appear numerous times in Neon World in version 0.08 and 0.09. They have two varieties and come in pairs, with a big one and a small one. They act similar to the numerous Shield-Folk.


A monster that doesn't look too far off from some of the ones in the White Desert, with its surrealistic design. It is absent from the original game, but has a role in YUMENIKKI –DREAM DIARY–.

Unused Train Passenger

Unused Train Passenger.png
A character who would most likely be another passenger on the Traincar. It does not appear in any version of the game and merely sits with the other character graphics.


Similar to the Zippertile, this Mesoamerican gate likely would have been used for the door leading to FACE. Interestingly, it only appears in the character graphics of version 0.08, unused.
