The Disappearance of Haruhi Suzumiya

The SOS Brigade is back, and their latest misadventure involves a rather mundane Christmas celebration. But when Kyon awakens on December 18th, he finds that Haruhi Suzumiya has vanished without a trace. Not only that, but the world around him has subtly, yet profoundly, changed. Yuki Nagato is now a shy librarian, Mikuru Asahina doesn't recognize him, and Itsuki Koizumi is nowhere to be found. As Kyon navigates this altered reality, he grapples with the unsettling realization that he might be the only one who remembers the way things truly were. With the fate of his friendships, and perhaps even reality itself, hanging in the balance, Kyon must unravel the mystery of Haruhi's disappearance and decide which world he truly belongs in.
