Urusei Yatsura 2: Beautiful Dreamer

Not all is normal in Tomobiki, even by its standards. The students have been preparing feverishly for the first day of the student fair, which is scheduled to go on the next day. However, problems arise when some begin to notice that the next day simply will not come. As the students begin to try to find the reason for the problem, their beliefs about reality and the world of dreams are challenged. (Source: ANN)Life is but a dream. Or is it? How do you know if you're awake, or just dreaming that you're awake? This may sound like a silly question - unless you're a student at Tomobiki High School!Something strange, stranger than usual, is happening at Tomobiki High School, but with wacky classmates like Lum (a beautiful alien princess with a "shocking" personality), Ataru (the lecherous loser she loves), and Mendou (the suave scion of the wealthiest family on Earth), anything can happen! When Ataru, Lum, Mendou, and the rest of the gang discover that they've been reliving the "day before the School Festival" over and over again, they may be confused, but they aren't suprised! But things are getting worse, and if they don't find a way to break the chain, they'll be trapped forever.
