Monoe (モノ江, derived from monochrome) is a character found in the White Desert A and many fans think of her to be Monoko's older sister. Her name comes from the "Picture/モノ江.xyz" file in the game, and is one of the few characters with an official name, other than Madotsuki, Monoko, Takofuusen, and a few others. She was added in version 0.07, along with the White Desert itself.
She is located in a tunnel near Dave Spector. To meet her, you must kill Dave Spector with the knife and walk into the tunnel from the west. She will be somewhere in the darkness - it is a good idea to use the Cat effect to locate her. Interacting with her will trigger a brief full-screen event, where a picture of her face will fade in and out upon the screen. After this, she vanishes away to another place in the area.
Monoe could be a vision of when Madotsuki was happy (or how she wants to be happy). She is one of the only characters that smiles and doesn't seem hostile (like Uboa) but then she disappears. Monoe and Madotsuki also share similar appearances.
