Tsubasa Hanekawa

Tsubasa Hanekawa is one of the main characters from the Monogatari anime and light novels.

Tsubasa is Koyomi Araragi's classmate, close friend, and a class representative in Naoetsu Private High School. She is known at school as an overachiever and model student who is admired by many. However, hidden by her achievements in school and her kind personality is a tense family life caused by unfortunate circumstances.

Appearance
Tsubasa is a teenage girl with glasses, black hair, purple pupils, and a fair complexion. She is stated to be beautiful by Suruga Kanbaru, Hitagi Senjougahara, and Koyomi Araragi. She is almost always seen wearing her Naoetsu Private High School uniform, even outside of school days.

Chronologically early on in the series she wears glasses and styles her hair into braids. In Kizumonogatari, she has only one pony tail while in Nekomonogatari Black and Bakemonogatari, she ties them into two with a hair ribbon that has a cat design.

After the events of Tsubasa Cat, she allows Koyomi to cut her hair as a symbol of her growth (Koyomi secretly keeps her braids). She also begins wearing contact lenses instead of her usual pair of glasses. After the events in Tsubasa Tiger, her hair has silvery-white stripes, resembling a tiger's, although she commonly dyes her hair back to its normal color each morning.

As shown during her moments as Black Hanekawa, Tsubasa has a slim figure and is well-endowed. Koyomi once commented in Tsubasa Family that Tsubasa's breasts are "so appealing that one would want to cop a feel." Another interesting detail is her rather unique choice of underwear, which is often decorated with lace.

Personality
To most people she interacts with, Tsubasa is a soft-spoken girl with a kind heart and a positive personality. Her top grades make her a favorite of the teachers, while her approachable character makes admirers out of her classmates. Tsubasa is also a wealth of information due to her study habits, but keeps humble about it, always stating that "I don’t know everything, I just know what I know" to those who commend her knowledge (although it should be noted that she only says this to Koyomi as this catchphrase makes Koyomi happy). She is never seen angry, but even when she does get mad, she retains her positive appearance, and often resorts to scolding the offender like a teacher, only to show a smile afterwards. The only instance where she is seen with a genuiely angry expression is during Sodachi Lost, when she confronts the trickster Ougi Oshino.

However, those who are familiar with her true identity know that all of those are a facade that she shows to the public. The truth is that she often does things without the sentiment that comes along with it, and moves only through common sense. She also possesses a strong sense of righteousness that becomes a double-edged sword, to the point of interacting with her may cause oneself to notice one's imperfections.

In Tsubasa Tiger, her personality was described as "accepting whatever comes her way without any objections" and "shunning all of her undesirable traits somewhere else". The latter was what caused the manifestation of Black Hanekawa and Kako, which symbolizes her stress and her envy and negative emotions, respectively.

Despite this, Koyomi stated that Hanekawa is the individual he respects the most. She is his first and best friend as well as his "savior" during Kizumonogatari, causing him to deify her as his "ideal girl."

Trivia

 * Tsubasa's first name means "wing" while her surname has the characters for "feather" and "river".
 * She is, to some degree, knowledgeable about foreign languages. In Koyomi Vamp, she mentions knowing enough Spanish to speak basic conversation and corrects Koyomi when using a Russian word incorrectly (although, she translates it incorrectly). In Tsubasa Sleeping, she speaks broken German while in Germany.
 * In the Kizumonogatari film adaptation, her email address when put into Koyomi's phone is shown as being "2ba3-nyannyan@XXXX.ne.jp" which to a Japanese speaker could be interpreted as "Tsubasan," a cutesy, informal modification of her first name. The "nyannyan," being a Japanese equivalent to "meow" is likely a direct reference to her relation to cats later in the series. She also notably makes a lot of cutesy cat-like faces in the adaptation.
 * Tsubasa Tiger was written in Tsubasa's perspective instead of Koyomi's, and was the first arc to do so.
