List of Haruhi Suzumiya Characters - Schoolmates

Schoolmates

Ryoko Asakura (朝倉 涼子, Asakura Ryōko?)

Voiced by: Natsuko Kuwatani (Japanese), Bridget Hoffman (English)

At first, Ryoko appears to be a compassionate and hard-working high school girl. One of Kyon's friends, Taniguchi, places her in the top three first-year girls in the school with a grade of AA+: indicative of her pleasant personality, beauty, and athleticism. Her enormous popularity made her the unanimous choice for class president of Kyon's homeroom class. She also showed particular concern about how Haruhi had distanced herself from the rest of the class.
However, it turns out that she is Yuki's backup, and as such, is also another "humanoid interface". Much like Yuki, she finds it difficult to empathize with humans, but unlike Yuki, possesses exceptional social skills. Initially she cheerfully supports Kyon's reaching out to Haruhi, often encouraging him to "open her up to the class," making Haruhi easier to observe. However, when Haruhi brings up the idea that someone disappearing would be interesting, it gives her the idea to try and kill Kyon (since Haruhi seems to care a lot about him) with a combat knife in the hopes of catalyzing an observable reaction from Haruhi. In battle, she mainly excels in controlling a select amount of data and making her own type of closed space, and hand-to-hand combat. Her efforts are stopped, after Yuki defeated and removed her from the physical world. It's interesting to note that her cheerful personality doesn't falter, even at the moment of her own demise. This is a clue given by the author that Ryoko really did not understand the concept or the heavy implications of death, may it be her killing Kyon or her own death; that in the end, what she did was the result of simple logic that if Kyon were to have died, then Haruhi would give a reaction, not for the purpose of bloodlust. Ryoko is very often called a yandere by fans. Afterwards, Yuki fabricates a cover story that Ryoko moved to Canada.
She makes a reappearance in the light novel The Disappearance of Haruhi Suzumiya, on an alternate timeline in which Haruhi never attends North High or forms an SOS Brigade. It is revealed that she cares deeply and is best friends with the alternate Yuki, but would still resort to violence to protect her, as she stabs Kyon when he tries to inject an uninstallation program into Yuki. However, she is stopped and destroyed by another Yuki that came from a few months later, along with Kyon and Mikuru, in order to save him. She appears again in book 10, "The Astonishment of Haruhi Suzumiya," preview released in 2010, when Kyon encounters Kuyoh Suoh, another humanoid data interface created by the Macrospatial Quantum Existence, or "Canopy Dominion" at the train tracks to save him. Her main duty is to appear whenever there is an emergency where Yuki is not available. Their fight is interrupted by Emiri Kimidori, another humanoid data interface created by the Integrated Data Sentient Entity, while Asakura was thrusting her combat knife at warp speed. She takes note that Kuyoh does not ask for any permission to alter data, and escapes the closed space. She disappears once again, but a note is taken that Asakura will appear when necessary. She does, in fact, appear hostile though, telling Kuyoh that Kyon is her "prey."
In the spin-off mini-series, The Melancholy of Haruhi-chan Suzumiya, she appears as a chibi form dubbed 'Achakura' as a basketball sized result of a failed reincarnation, and is forced to help Yuki around her house. She is also subject to pranks from Yuki, such as being transported around in a baby carrier or dressed up like a Hinamatsuri doll. In Nyorōn Churuya-san, her appearance is similar to Tsuruya/Churuya and she has a crush on Kyon. She is also one of the main characters in the spin-off manga, The Vanishing of Nagato Yuki-chan.

Tsuruya (鶴屋?)

Voiced by: Yuki Matsuoka (Japanese), Kari Wahlgren (English)

Tsuruya is the hyperactive friend of Mikuru (from the current time plane) notable for her loud voice, knee-length hair, and prominent tooth. She possesses a cheerful and friendly disposition. She is also prone to long fits of unrestrained and intense laughter at things she considers even the slightest bit humorous.
Her fang-like tooth gives her an idiosyncratic speech pattern, causing her to misspeak words by leaving out syllables. Her speech pattern is often accompanied with a lisp and her catch phrases "megas" and "nyoro". She was named "honorary consultant of the SOS Brigade" by Haruhi. She is also the heir of the Tsuruya family, which purportedly collaborates with Itsuki's Agency. It is also unknown if Tsuruya has a secret identity or agenda.
Though not an actual member of the SOS Brigade, she does play a minor role in The Adventures of Mikuru Asahina Episode 00 and serves on their baseball team in episode four. She also has a small appearance in the ninth and twelfth episodes of the anime, but otherwise appears relatively sparingly throughout the anime. She appears a few more times during the novels, appearing more prominently than in the anime's rendition of the same stories, and even getting along very well with Haruhi. Kyon believes this is because both Haruhi and Tsuruya are nearly insane. Though she is not a brigade member, Tsuruya is still used as an extra body for some of the Brigade's activities.
In the light novels, it is implied that Tsuruya's wealthy and venerable family is a covert supporter of "the Agency" to which Itsuki Koizumi belongs. Tsuruya herself seems to possess some knowledge of the secrets of the SOS Brigade and other matters, although she never explicitly says so. Tsuruya temporarily takes care of Mikuru Asahina during an event when the latter has a double presence in the 'present' of the SOS Brigade and is also the caretaker of a mysterious artifact discovered on her family's grounds, both at Kyon's request.
In the original light novel The Disappearance of Haruhi Suzumiya, Tsuruya's role in the altered reality is that of Mikuru Asahina's best friend. She is shown to be extremely protective of her, even resorting to violence to keep her safe, but still maintains her cheerful disposition.
She is the star of the official gag manga, Nyorōn Churuya-san, featuring a super deformed Tsuruya with a smoked cheese obsession, which later became an anime mini-series. She also makes various appearances in The Melancholy of Haruhi-chan Suzumiya where she apparently has a rivalry with Sonou Mori.

Taniguchi (谷口?)

Voiced by: Minoru Shiraishi (Japanese), Sam Riegel (English)

Taniguchi is a classmate and friend of Kyon. Taniguchi went to the same junior high school as Haruhi while Kunikida went to the same junior high school as Kyon. Like Tsuruya and Kyon's sister they act as fill-in members for the SOS Brigade whenever needed. Both of them played very small parts in The Adventures of Mikuru Asahina Episode 00, with neither having many lines to say. They are friends and are almost always seen together.
Taniguchi is comically lascivious; he gave a 'score' of attractiveness to each first-year girl based upon his tastes and preferences. He remembers the full names of everyone receiving an 'A' rank, with Ryoko receiving an A++ and Nagato receiving an A-. As for Mikuru, her mere presence elicits an altered state of adoration for Taniguchi and Kunikida, especially when she was in her soba-serving costume. He also knew Haruhi from back in junior high, and was Kyon's original source of information on Haruhi before he started conversing with her. Kyon's opinion is that Taniguchi may have been the person who dated Haruhi for the shortest amount of time, five minutes, while she was in junior high. Kyon does not seem fond of Taniguchi. He seems to show annoyance with Taniguchi whenever he speaks his mind. In the novels, he says he only hangs out with Taniguchi so as not to look like an outcast.
In The Melancholy of Haruhi-chan Suzumiya he usually gets the short end of the stick in the episodes that he appears in. This includes being on a scavenger hunt for so long that the game was over when he came back and becoming an "oni" when in fact all that Haruhi assigned for him was to sit still in "icy isolation".

Kunikida (国木田?)

Voiced by: Megumi Matsumoto (Japanese), Brianne Siddall (English)

Kunikida is a friend and classmate of Kyon. Kunikida is much quieter than Taniguchi with the latter doing most of the talking when the two are around. Kunikida plays a minor role and does not contribute much dialogue. However since he and Kyon went to the same junior high school, he might know more about Kyon since he once stated that "Kyon likes weird girls," as evidence to support the idea that Kyon is romantically interested in Haruhi. His character is also shown to be smarter than his friends Taniguchi and Kyon, at one time explaining a difficult concept to Taniguchi. Kunikida is also included in certain SOS Brigade activities when there is a shortage of people, such as the baseball game and the movie The Adventures of Mikuru Asahina.

The Computer Research Society President (コンピュータ研究会部長, Konpyūta Kenkyūkai Buchō?)

Voiced by: Nobuyuki Kobushi (Japanese), Dave Wittenberg (English)

He is the President of the Computer Research Society (or Computer Society), which shares a room adjacent to the SOS Brigade. The President is never given a name other than "Computer Society President" or variations upon that term (all that is known of his name is the first syllable: "ya"). He and his club have had the misfortune of being targeted by Haruhi's blackmail, being forced to give away their best computer and wire the Brigade's clubroom for an internet connection. He hasn't yet forgiven this, and checks the SOS Brigade website to see if they are putting the computer to use (which they haven't), making him the primary cause of their hit counter's steady rise.
He has a passion for computers and has, with the other four members of the Computer Society, developed their own basic science-fiction strategy game titled The Day of Sagittarius III (there is no Day of Sagittarius I or II, they just thought the III would sound cool). He later challenges the SOS Brigade to a rigged contest using their game, betting four of his club's laptops in an attempt to reclaim the originally pilfered computer. Despite the Research Society's cheating, Yuki counters by reprogramming the code in-match, and the SOS Brigade wins. Despite the loss of four additional laptops, the President was at least overjoyed at having discovered a genius computer hacker that would participate in his club's activities. In the light novels, it is hinted he is one of Nagato's secret admirers.
In the episode/chapter "Mystérique Sign", he is trapped in an alternate spatial frame that was unknowingly triggered by Haruhi. He was, in turn, freed by the other members of the SOS Brigade.

Emiri Kimidori (喜緑 江美里, Kimidori Emiri?)

Voiced by: Yuri Shiratori (Japanese), Hynden Walch (English)

A soft-spoken, well-groomed second-year student with long, light green hair, Emiri first appears in "Mystérique Sign" seeking counsel from the SOS Brigade. Although she claims to be the girlfriend of the Computer Research Society president, Kyon later discovers that this is not the case, which leads him to suspect that Emiri is a Humanoid Interface like Yuki and Ryoko.
Emiri later reappears as the secretary to the president of the Student Council. By this time, it is implied that she is Yuki's superior, or at the very least her minder, as a consequence of Yuki's world-altering actions. Emiri is also later shown to work part-time (and against the rules of the School Council) as a waitress in the cafe frequented by the SOS Brigade.
Student Council Chairman (生徒会長, Seitokaichō?)
A student chosen by Itsuki's "method" and hired by the Agency to play the part of the archetypal nemesis to Haruhi, as yet another attempt to relieve her stress. He attacks the Brigade, usually on the grounds that it is not a legitimate club, using the school rules. When acting as Haruhi's nemesis, he wears glasses and acts cold and polite. When Haruhi is not present, he drops this façade, removes his glasses and sometimes smokes cigarettes. He has noted that he is growing accustomed to his role and that he enjoys wielding power. His name remains unknown.
