Yesterday, Kyon was helping prepare for an SOS Brigade Christmas party. But today, he wakes up to a whole other world. Haruhi and the SOS Brigade are gone, Koizumi's class is missing, Asahina doesn't recognize him, Nagato is still a Literary Club member and even Ryoko Asakura has returned. As the only person who notices that everything has changed, Kyon is left to discover what happened to his friends and figure out if his life truly is better without aliens, time travelers and ESPers.
