Itsuki is the last member to have joined the SOS Brigade, having been recruited by [Haruhi Suzumiya](https://anilist.co/character/251/Haruhi-Suzumiya) as a "mysterious transfer student". Itsuki is constantly smiling and always speaks in a formal and polite manner. He is also prone to giving long and detailed explanations, usually illustrated by exaggerated hand gestures. Itsuki's fondness for speculation often causes him to produce explanations for situations involving the SOS Brigade, its members and related events. Itsuki only tends to share these explanations and theories with [Kyon](https://anilist.co/character/252/Kyon), and also enthusiastically plays different kinds of board games with him to pass the time, despite losing all the time, although Kyon suspects that he may be doing so on purpose. 

~!Itsuki is an Esper, and was sent to observe and keep Haruhi emotionally stable by a mysterious group known as "The Agency", in order to protect the rest of humanity. Although he is an esper, which is exactly one of the sorts of people Haruhi desires to meet, Itsuki never reveals himself as such, at least, not to her. Despite the theory he advances in which Haruhi is the equivalent of God, Itsuki says that there are many differing lines of speculation about Haruhi within "The Agency." Itsuki himself does not believe in a singular God, nor does he regard Haruhi as such, although he reveals that he has colleagues that do. Apparently, most of the questions that he raises about Haruhi's true nature are philosophical in nature and do not necessarily represent his personal beliefs. Itsuki also reveals that the majority of "The Agency" advocates observing Haruhi instead of doing anything that might provoke her.   

Out of the three Brigade members, Kyon is the least fond of Itsuki. He often finds himself annoyed with Itsuki's plastic smile, his willingness to acquiesce to Haruhi's outrageous schemes, playful teasing and his various forays into his psychological and philosophical theories. He is also distrustful of Itsuki's intentions, comparing him to [Yuki Nagato](https://anilist.co/character/249/Yuki-Nagato) when it comes to deciphering his expressions.!~  

It is mid-December, and SOS Brigade chief Haruhi Suzumiya announces that the Brigade is going to hold a Christmas party in their clubroom, with Japanese hotpot for dinner. The brigade members Kyon, Yuki Nagato, Mikuru Asahina and Itsuki Koizumi start preparing everything for the party, such as costumes and decorations. But a couple of days later, Kyon arrives at school only to find that Haruhi is missing. Not only that, but Mikuru claims she has never known Kyon before, Koizumi is also missing, and Yuki has become the sole member of the literature club. The SOS Brigade seems to have never existed, nor has Haruhi Suzumiya. No one in the school has ever heard about her... except for Kyon.

Kyon, your typical high school student, has long given up his belief in the supernatural. However, upon meeting Haruhi Suzumiya, he quickly finds out that it is the supernatural that she is interested in; aliens, time travelers and espers among other things. When Haruhi laments about the lack of intriguing clubs around school, Kyon inspires Haruhi to form her own club. As a result, the SOS Brigade is formed, a club which specializes in all that is the supernatural. 
Much to his chagrin, Kyon, along with the silent bookworm, Yuki Nagato, the shy and timid Mikuru Asahina, and the perpetually smiling Itsuki Koizumi, are recruited as members. The story follows the crazy adventures that these four endure under their whimsical leader, Haruhi. The story is based on the light novels by Nagaru Tanigawa. 
Note: This entry is for the original 14-episode 2006 airing. The series was further expanded and reordered into <a href="https://anilist.co/anime/4382/Suzumiya-Haruhi-no-Yuuutsu-2009/">a 28-episode series in 2009.</a>

Kyon has found himself dragged through many adventures as of late—all because of the SOS Brigade club and its excitable leader, Haruhi Suzumiya. He has stopped believing in the supernatural long ago, but after being forced to join this club based solely on that, he has seen things that cannot be explained logically. 
 
Joining Kyon on his various misadventures is the shy and soft-spoken Mikuru Asahina, the bookish Yuki Nagato, and the ever-cheerful Itsuki Koizumi. Whether it is summer vacation or a school festival, things involving their club and Haruhi herself always end up becoming strange. 
 
Note: This is a re-airing of the original Suzumiya Haruhi no Yuuutsu series, taken from the DVD release and aired in chronological order, adding 14 additional episodes with new content. These new episodes are episodes 8 (Bamboo Leaf Rhapsody), 12-19 (Endless Eight), and 20-24 (The Sigh of Suzumiya Haruhi Parts 1-5).

This spin-off of the Haruhi Suzumiya series takes place in the world of the "Disappearance" arc of the original novels, focusing on the high school life (and romance!) of a tentative and bashful Yuki Nagato quite unlike the one you've come to know and love through the usual exploits of the SOS Brigade... but no less charming! 
 
As the shy head of the Literature Club, Nagato has had a hard time recruiting members. Her close friend Ryoko Asakura supports her in this. Drafting Kyon, she eventually meets up with Haruhi Suzumiya, Tsuruya, Mikuru Asahina and Itsuki Koizumi, and has to put up with their hijinks while trying to romance Kyon. Asakura seems ambivalent about the latter prospect.

Kyon is your ordinary high school freshman who has long given up on his childhood dreams of encountering the fantastic and supernatural…or so he thought. From the very first day of school, his classmate–the beautiful but eccentric Haruhi Suzumiya–makes it very clear that her only desire is to meet aliens, time travelers, and psychics! A chance conversation between the two inspires Haruhi to form the SOS Brigade, a school club created for the sole purpose of getting these supernatural beings together. The initial members consist of the mute bookworm Yuki Nagato, the timid but voluptuous Mikuru Asahina, and the polite and ever-smiling Itsuki Koizumi. By the end of this first volume, Kyon quickly finds out that these seemingly “helpless victims” of Haruhi’s are actually members of secret organizations–both futuristic and alien–keeping watch over Haruhi as she is the pinnacle of some major calamity on the horizon…

WHAT IF YOU WOKE UP ONE MORNING, AND EVERYTHING HAD CHANGED? 
It’s one week before Christmas Eve, and Haruhi and the rest of the SOS Brigade are gearing up for holiday festivities. But just before the fun kicks off, Kyon, the only “normal” member, wakes up in a weird alternate dimension, one where Haruhi attends another school entirely, Nagato the time traveling robot is just an ordinary human, and Mikuru (the cute girl of Kyon’s dreams) doesn’t even recognize him—in other words, the SOS Brigade never existed.
 
The only clue Kyon can find is a bookmark left by the robot version of Nagato, which leads him on a quest back in time, where he once again encounters the events of “Bamboo Leaf Rhapsody,” a short story from the previous Haruhi book, The Boredom of Haruhi Suzumiya. This fun and quirky holiday tale is reminiscent of A Christmas Carol and It’s a Wonderful Life.

A parody series featuring the entire cast of The Melancholy of Haruhi Suzumiya in a smaller form factor. Among the changes are: Yuki plays eroge, Haruhi is even more obnoxious and loud, Mikuru is even more emotional and Koizumi harbors a deep love for Kyon. Kyon, on the other hand, is generally the same as ever.
