Haruhi Suzumiya

"I have no interest in ordinary humans. If there are any aliens, time travelers, sliders, or espers here, come join me. That is all."

- Haruhi Suzumiya

Haruhi Suzumiya is the main heroine and title character of the Haruhi Suzumiya series of light novels and the anime based on them. She is the founder and leader of the SOS Brigade, a club she created with the purpose of finding aliens, time-travellers and espers. Although she doesn't know it, all the members of the SOS Brigade she recruits, besides Kyon, happen to fit into these groups (Yuki Nagato, Mikuru Asahina, and Itsuki Koizumi respectively). She is incredibly eccentric and anti-social, with no interest in "ordinary" humans.

She also, unknown to her, has god-like abilities to change, destroy, and reshape reality. It is said that if she were to become bored enough with the world, she could create closed space, meaning a new world which could prevent destruction in the "real world". After revealing themselves to Kyon, the trio of Yuki, Mikuru and Koizumi all state they were sent by their respective higher-ups to watch over her, and Koizumi specifically mentions they must keep her entertained so she doesn't become too bored.

She is voiced by Aya Hirano in the Japanese version of the anime and Wendee Lee in the English version.

Appearance
Haruhi has a pale skin tone, big brown eyes and brown hair. At the beginning of the series her hair is long and reaches to about her waist. She always had different hairstyles everyday. However after a talk with Kyon about her hair, she cuts it to just about her shoulders. Haruhi is always seen wearing a orange-yellow ribbon/head band in her hair.

Personality
Haruhi is a bright, energetic and athletic high-school student. Many male students consider her attractive. She alternates between melancholy and incredible optimism, often unpredictably. Her behavior was considered eccentric, and she had little interest in her classmates, at least until Kyon "convinced" her to form the SOS Brigade. Afterward, she became more mentally stable and gradually connected with schoolmates in club activities.

First in Snow Mountain Syndrome and later in The Astonishment of Haruhi Suzumiya, it is mentioned she is good at cooking. Haruhi reveals that the reason why she is good at cooking is due to her mother having "awful taste" and always measuring ingredients and spices by the eye causing every meal she makes to "never taste quite the same each time" so in primary school (elementary school) Haruhi attempted to cook on her own and found that she had somewhat of a natural talent for it and insisted on cooking her own meals ever since. Her mother's low cooking skills are also the reason why Haruhi never brings a lunchbox to school. Interestingly enough, this all of the information Haruhi reveals (with reluctance) about her mother upon mentioning her for the first time other than saying "She works a lot, and so we help each other out."

Kyon criticized Haruhi's tea making skills, noting it was just hot water.

Though Haruhi's personality may be described as overpowering, it's useful to say the least. Haruhi has a knack for convincing others to do what she wants.

Early life
When Haruhi was in sixth grade, she went to see a baseball game with her parents and was shocked by the sheer amount of people attending. After finding out that the large amount was only a small piece of the entire world, and realized that she was only a small part of it, Haruhi believed herself to be ordinary, and deduced that if there is someone out there with an interesting life that it should be her. This results in Haruhi's desire to find strange things. During elementary school, she came to know Sasaki, under the surname Sasaki was using at the time.

Middle school years
In middle school, East Junior High, Haruhi becomes known for several things, such as putting talismans up around school, dating and often immediately dumping every guy who asks her out, and, most notably, drawing a huge graffiti mural on the field on the night of Tanabata, year 0.Kyon was actually the one who drew this under Haruhi's orders after he andMikuru traveled back in time. (According to Yuki Nagato, the mural meant "I am right here".) Thanks to the dark, Haruhi could not make out his face, and so Kyon used the alias "John Smith" to further keep himself secret. "John Smith" implied to Haruhi that there were strange things out there and that there might be interesting people at North High, inspiring her to attend the school.

Shortly after, the same night (from Haruhi's perspective), Kyon shouted out to her "Cheers to saving the world by overloading it with fun with John Smith!" after returning the second time from the future in theDisappearance.

The consequences of her ability erupting was a timequake preventing time traveling to before this point. This also seems to have sundered the timelines of Fujiwara and Mikuru Asahina.

Until she went to high school, Haruhi sought "John Smith" at other schools, but was unable to find him.

Powers
Haruhi has the ability to create reality (or "data"), but the power is unconscious and she is unaware of it. Just by thinking, she can alter reality. Sometimes this manifests as the ability to make something of her desires truly exist, such as closing off a remote island with fog (to enhance the atmosphere of a murder mystery). When she is overjoyed, her abilities have changed the weather, made animals speak and even changed the orbit of the Earth.

Many of her powers are implied in the series and not stated outright. In The Melancholy novel, class president Ryouko Asakura (secretly a humanoid interface) changed the class seating patterns numerous times, but in every instance, Kyon ended up sitting in front of Haruhi. Kyon couldn't understand why he felt the need to attend the SOS Brigade's early meetings.

In Mystérique Sign, Yuki Nagato said Haruhi's abilities summoned or awoke a data organism (creating terabytes of data in what seemed like a simple image), and in Wandering Shadow it was implied that Haruhi's abilities summoned another type of data organism. In the first case, Nagato was able to reverse Haruhi's alteration of reality.

In Endless Eight, Haruhi's powers created a time loop, which she herself never noticed, nor did most humans, but Kyon, Koizumi and Asahina often did. (Nagato was fully aware of the time loop due to her humanoid interface nature.)

Closed Space
When her emotions become unstable, she subconsciously creates closed space and celestials which begin to take over the world, destroying things. Agency espers such as Itsuki Koizumi believe it is their duty to destroy the celestials, restoring normal space. Koizumi said that the system was born of "common sense"; Haruhi encloses the celestials in closed space to prevent destruction in the "real world". According to Itsuki Koizumi, Haruhi's powers created espers like himself, time travel and even aliens such as Yuki Nagato. (This is in contrast to time traveler Mikuru Asahina, who vehemently disagrees with this. Nagato stated that her organization, the Integrated Data Sentient Entity, existed even before humanity, which would conflict with Koizumi's statement as well.)

Koizumi said that Haruhi has the power to create a new world (destroying the old one in the process) and the "current world" came to exist as a result of Haruhi's power. As a result, some of the Agency believes Haruhi to be a "god". While Koizumi initially said he might agree with this statement, he later admitted to being a skeptic, saying that if she were a god, she could not live in this world without becoming self-aware, but since Suzumiya lives in the world she can alter without noticing, Koizumi concludes that she can only alter the world to a certain extent.

He states that Haruhi does not really believe in espers, aliens and time travelers, and they only exist because she subconsciously wishes them to do so. If she ever became aware of them, or other strangeness such as "talking cats", she would recreate the world in such a way that talking cats made sense. Koizumi feared this would "overthrow all the concepts already known to mankind".

Koizumi believes that someone granted Suzumiya these powers, but also prevented her from knowing about them. This entity is more likely to be a god. "The reality right now may be a failed product of creation, and perhaps Suzumiya-san was given the mission to amend this flawed world."

If the world were recreated, humanity could be wiped out, but this hasn't happened, due to her consciousness leaning toward creation rather than destruction. If her mentality became negative, she might focus on destruction.

Koizumi prefers to live in the "current" world despite its problems, as humans would eventually sort them out.

Rival esper Kyoko Tachibana believes that Sasaki originally had these powers, and some were mistakenly transferred to Haruhi. She wishes to move these powers back to Sasaki. She and Koizumi strenuously disagree on these beliefs.

According to time traveler Mikuru Asahina, "Suzumiya-san does indeed possess the power to change the 'present,' but I don't think she has the ability to reconstruct the world. This world has been this way since the beginning, it's not created by Suzumiya-san."

Sasaki has similar abilities, signifying that Haruhi is not the only one with these powers. Esper Kyouko Tachibana believes that Sasaki originally had these powers, but they were "stolen" from her and given to Haruhi instead. Tachibana wishes to recover this power.

Creating Alternate Realities
Haruhi has the ability to split and recombine reality into two alternate parallels. She demonstrated the ability to subconsciously create a younger copy of herself, Yasumi Watahashi.

In The Disappearance Yuki Nagato was able to "steal" Haruhi's abilities, creating yet another reality, although the changes were eventually reversed by previous and future versions of herself, Mikuru Asahina (big) and Kyon.
