Garasu no nô

A story of a young girl who ever since her birth, has never been awake. Seven years after birth, a little boy called Yuuchi encounters the girl while he's exploring the hospital he's in. After a nurse remarking to him that the girl, Yumi, is a 'sleeping beauty', Yuuchi believes that just like in the story, if Yumi is kissed by a prince, she'll wake up. Then, after ten years, he goes back, says the words and... Yumi wakes up! (imdb)
