Usotsuki (うそつき)

Overview
Usotsuki (うそつき) (lit. liar)  is the main character in Yume Nisshi. (Not to be confused with Urotsuki (Yume 2kki Protagonist)

Appearance
Usotsuki has short shoulder-length blond hair, a dark blue tank top dress, and pale purple shoes. Typically in fanart she is depicted to be shorter than most dreamers, possibly younger, but not as young as Chie.
