Nire (にれ) is the protagonist of Yuque. She lives in a small apartment and refuses to leave her room for unknown reasons. The menu notes that she has Somniphobia. (https://yumenikkifg.fandom.com/wiki/Nire_(にれ))

Little can be said about Nire's personality as she does not talk in the game. What type of personality she has is left to the player's interpretation.

The menu mentioning her as somniphobic means that she fears falling asleep, although it is not yet known why or how this fear developed.
