The Vanishment of Haruhi Suzumiya (涼宮ハルヒの消失, Suzumiya Haruhi no Shōshitsu), or The Disappearance of Haruhi Suzumiya, is an upcoming animated film based on the fourth light novel of the Haruhi Suzumiya series of the same name. It is in production by Kyoto Animation and will be released in Japanese theaters in February 2010.
The story takes place from December 17 until December 24, a month after the cultural festival. On December 17, everything is normal. The SOS Brigade, led by Haruhi Suzumiya (Aya Hirano), plans to have a nabe party [I think that's a kind of Japanese celebration] for Christmas. However on December 18, Kyon (Tomokazu Sugita) arrives at school to find everything has changed. Haruhi and Itsuki Koizumi (Daisuke Ono) are missing, Yuki Nagato (Minori Chihara) is an ordinary human, Mikuru Asahina (Yūko Gotō) does not recognize him and Ryoko Asakura, who had previously been deleted by Yuki, is a normal student. Only Kyon is aware that everything is different. The only clue is a bookmark left by the alien version of Yuki, which leads Kyon on a quest to reunite the SOS Brigade and go back in time, where he interacts with the storyline from "Bamboo Leaf Rhapsody", trying to sort out the mystery and return to his own time line.
As you can tell, information is limited right now, but I look forward to seeing it (on the internet) with subtitles (which will probably be a few weeks after it's available in Japan).
I'm really excited about this. This will be one of the greatest moments in my life.
So who else is excited about the upcoming movie?
