In a last-ditch attempt to recover their stolen equipment, the Computer Research Society challenges the SOS Brigade to a winner-takes-all multi-player space battle simulation! Failure seems inevitable, but losing is not an option! Can the unique members of the SOS Brigade pull together to destroy the expert Computer Research Society before Haruhi destroys the whole city?
Guided only by a series of notes that direct him to do the most inexplicable things-"Buy a small turtle and throw it into the lake"?-Kyon and the Mikuru from eight days in the future complete the assigned tasks, hoping that things will become clear as the SOS Brigade's adventures for that week continue. But Kyon and Mikuru's scavenger hunt soon turns to a manhunt when Mikuru is kidnapped by a group of rogue espers, time travelers, and aliens!
After months of squatting in the Literature Club's clubroom, the SOS Brigade puts pen to paper and starts writing some literature of their own! The Brigade has just one week to create a literature newsletter if they want to keep the Lit Club's space from being reallocated by the student council. As each member prepares his or her contribution, Supreme Editor in Chief Haruhi keeps a watchful eye on her team, especially as Kyon's assigned romance story unfolds!
When Kyon arrives at school, it seems like another average day--until he realizes Sasaki has wrapped North High in a closed space. Led to the SOS Brigade clubroom by Sasaki and Tachibana, Kyon knocks (just in case) and is surprised to find not a costumed Asahina, but instead a girl he's never seen before...and a very familiar face!
Something very, very strange is going on...because nothing strange is going on...Overnight, the SOS Brigade, the existence of supernatural beings, and Haruhi Suzumiya's obsession with finding them (not to mention Haruhi herself!) have disappeared. Has the goddess lost her touch? And why is Kyon, who so often longed for a normal life, so upset to find all of it suddenly gone?
Trapped on the snowy mountain by both a storm and the supernatural forces that have cut off Yuki from the Data Overmind, Kyon is roused from sleep by Asahina slowly unbuttoning her nightshirt as she climbs into his bed! Kyon realizes it cannot possibly be the real Asahina (darn!), and though he doesn't mind the house's tricks (who would?), he and the Brigade have to crack the code and escape fast before Yuki's fever (and Haruhi's restlessness) gets out of control!
Say Haruhiiiiiii! As if he doesn't have enough to deal with during the day, Kyon's dreams are becoming a regular haunt for his SOS friends! Once again, lucky(?) omens hawk, eggplant, and Mount Fuji (played respectively by Tsuruya, Nagato, and Koizumi) make an appearance, but their promises of fortune never seems to play out for Kyon. All he ever gets is more of Haruhi-chan's antics! You'll find plenty of gags and guffaws as Haruhi dives into the world of four-panel and short comics!!
One weekend, when Kyon reaches the usual SOS Brigade rendezvous spot, he is met not by his fellow club members, but instead by Sasaki, an old friend from middle school. Haruhi isn't thrilled to find Kyon already waiting when she arrives (Who's going to buy drinks?!) and is even less thrilled by his attractive female friend!
Quite out of the blue, Kyon receives a phone call from his middle school classmate Nakagawa. Six months ago, he spotted Kyon walking with the most beautiful girl he'd ever seen and instantly fell in love! Now he wants Kyon's help conveying his feelings. But Nakagawa has no idea that the fair maiden who stole his heart is actually an otherworldly being...Nagato?! How will the stoic alien react to Nakagawa's affections?!
After Haruhi's rigorous selection process, a new member has been selected for the SOS Brigade! But Kyon feels uneasy around Yasumi Watahashi, not only because of the girl's odd behavior, but also because he knows the peculiar-and sometimes threatening-types that tend to congregate around Haruhi Suzumiya...
