Madotsuki is the playable protagonist of Yume Nikki. She is one of the few characters in the game with an official name. As with virtually everything else in the game, Madotsuki's identity and life are a mystery. Only what can be seen in-game can be considered canon, although there are many varying interpretations of her as her dreams are vague and sometimes disturbing. In the Yume Nikki game, there is no context nothing. Just the unknown.
