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 places. 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.
