1Asahina Mikuru no bôken: Episode 00
In the first, yet bizarre episode, we follow the adventures of a time traveler (Mikuru Asahina) as she protects an esper (Itsuki Koizumi) from a powerful alien (Yuki Nagato). What is supposed to be an adventure full of suspense and thrills turns out to be a disastrous production by the SOS Brigade full of bad acting, poor editing and over the top action with sarcastic delivery by our narrator Kyon. But in the end, the director who is no other than Haruhi Suzumiya calls the film a success and plans to send it to the film festival.
2Suzumiya Haruhi no yûutsu I
Our narrator, Kyon, a normal human being, has just entered North High School, with no aspirations of any sort. He has discarded his childhood fantasies of aliens, time travelers and espers and hopes to enjoy a monotonous year of school. Then he meets Haruhi Suzumiya, also a first year who is interested in seeking aliens, time travelers and espers and doesn't care about human beings. She is believed to be a very closed, yet eccentric person who is said to have drawn lines across the school yard of her middle school to attract aliens. Kyon starts talking with her before class and gets her to open up to him. However, one day he goes too far and inspires Haruhi to action immediately where she creates her own club called the SOS Brigade with him and two others as members. Kyon now realizes that he has entered a hell that he can't escape from, which could impact the rest of his life forever.
3Suzumiya Haruhi no yûutsu II
Continuing from the last episode, Kyon is now forced to come after school every day to the new clubhouse of the SOS Brigade. He meets the other two girl members, Yuki Nagato, a monotonous first year who voluntarily joins them from the Literary Club and Mikuru Asahina, a sexually attractive girl, who is forced to join and later is sexually harassed by Haruhi Suzumiya every day. During this episode, Haruhi blackmails the computer society into giving her a computer; she and Mikuru cause a ruckus by handing out flyers to students at the front gate wearing bunny girl costumes and Kyon now realizing what the SOS does. In the end, Yuki invites Kyon to her home and reveals herself to be an alien watching and accessing data on the actions of Haruhi, who is not an ordinary human being.
4Suzumiya Haruhi no taiketsu
Thanks to her eccentric behavior, Haruhi signs up the SOS Brigade into a baseball tournament, because she wants the SOS to be more known to the public. However, Kyon knows that they will lose anyway and plans not to take it seriously. But, the other members know that if the SOS loses, Haruhi could destroy the current world without knowing. So, in a wild finish, thanks to Yuki, the SOS Brigade wins the first round against the number 1 seed and everything is fine.
5Suzumiya Haruhi no yûutsu III
Continuing from the third episode, Yuki, Mikuru Asahina (a real time traveler) and Itsuki Koizumi (an esper, who joins the club in this episode) reveal their identities and purposes to Kyon. They all believe that three years ago, Haruhi created the current world and that their organizations are supposed to monitor her activities. If she becomes bored or angry, she could create a new world, destroying the current one, causing chaos. Therefore, she should not know anything of her powers, lest she creates another world as a result. They also tell Kyon that he is the cause of Haruhi's sudden spark, because it was he who inspired her to action. Now he and Haruhi are connected by the bond of trust which must remain constant forever. Meanwhile, Haruhi, oblivious to what's happening, arranges for the SOS to look for the "mysteries of the world", but Kyon wastes time with Mikuru and Yuki, by doing nothing, pissing off Haruhi with his behavior. In the end, they don't succeed and waste a lot of Kyon's money in the process.
6Kotô shôkôgun: Zenpen
After exams are finished, the SOS Brigade takes a cruise to a remote island that is planned by Itsuki. Kyon's sister tags along as well, much to the chagrin of Kyon. Once they arrive, they meet Keiichi-san, the owner of the villa they are staying at, his brother Yutaka-san, the butler Arakawa-san and the maid, Mori-san. Haruhi starts thinking that a murder mystery might occur, but Kyon tells her they only just arrived. So, the first day is spent at the beach. But the next two days are spent inside, because of a typhoon and Haruhi really believes something interesting will happen. And on the third day it does, as Arakawa-san tells them that Yutaka has disappeared and Keiichi hasn't stirred from his bed. So they go to Keiichi's room and find him...
7Misuterikku sain
The SOS Brigade is back at school, with Kyon designing their new website and Haruhi coming up with their logo, which Kyon despises. Nothing really happens, until Haruhi notices something wrong with the logo, and later a surprise visitor arrives, asking for help from the SOS. She claims that her boyfriend (the Computer Society President) has disappeared from the earth and has never returned. So the SOS go to his apartment to investigate and return with nothing. However, Itsuki and Yuki know something isn't right, so they take Kyon and Mikuru back to the apartment. There they transfer to a different world, created by a fragment of Haruhi's imagination in a form of a cave cricket, where the President is trapped inside. Itsuki and Yuki successfully destroy the cave-cricket, return the president back to his room and restore everything back to normal. Kyon later realizes that everything was made up from the start just to relieve Haruhi from her boredom and life goes on...
8Kotô shôkôgun: Kôhen
After the 6th episode, the SOS (namely Haruhi and Kyon) go and investigate the murder of Keiichi-san in his room. At first, they believe that Yutaka-san killed Keiichi-san after an argument and fled. However, after a search in the rain where Kyon saves Haruhi's life, Haruhi suddenly realizes that it wasn't what they thought it was. Back inside, Itsuki provides Kyon with more information about the murder. But in the end, it is all a hoax as Keiichi-san is not dead at all and Haruhi recounts the whole mystery with Kyon grumbling along. The next day, they leave the island and Itsuki reveals to Kyon that the people on the island were all espers working with him and the island was only created to the expense from preventing Haruhi's boredom.
