The Disappearance of Haruhi Suzumiya

In mid-December, the SOS Brigade is preparing a Christmas party when Kyon arrives at school to find reality inexplicably changed. Haruhi Suzumiya has vanished, Mikuru Asahina says she has never met him, Itsuki Koizumi is gone, and Yuki Nagato is simply the lone member of the literature club. Even more disturbing, nobody at school remembers Haruhi or the SOS Brigade at all. Kyon appears to be the only person who knows that something is wrong.
