Tsubasa Hanekawa

She styles her hair into two braids and ties them with a hair ribbon that has a cat design. She is always seen dressed in the uniform of Naoetsu Private High School, even outside of school days, and is rarely seen on any other type of clothing, except for a set of sleepwear which she wore during Tsubasa Cat Arc. Hanekawa Tsubasa is Araragi's classmate and the class president. Araragi describes her as "the class president of all class presidents". Her catchphrase is "I don’t know everything, I just know what I know". Hanekawa currently lives with her stepfather and stepmother.

Hanekawa Family's Past: Her biological mother was 17 years old when she got pregnant, the biological father is unknown because she apparently had many lovers. Before she gave birth to Tsubasa, she married another man who was a "workaholic". Right after giving birth, Tsubasa's biological mother commited suicide. The workaholic stepfather, unable to raise a child, remarried again to a woman who is Tsubasa's current mother. The workaholic father soon died from overwork and the current mother married another man who is now Tsubasa's current father. Hanekawa Story's overview in Nekomonogatari/Bakemonogatari:

Prior to the beginning of Bakemonogatari, Hanekawa was possessed by the mischievous spirit of a dead cat during Golden Week due to stress over her family. The matter was eventually resolved with the help of Shinobu at the cost of some of Hanekawa's memories, but the problem emerged again right before the school festival because of different stress. Araragi was told by Hanekawa's bakeneko form that she has feelings for him. In 'Tsubasa Tiger' (Nekomonogatari: Shiro), on her way to school, she met a tiger spirit which spoke to her. Soon buildings important to Hanekawa began to mysteriously burn down and 'Black Hanekawa' (her bakeneko form) began to take over her body every time she slept. The inevitable showdown was afoot and led to some surprising events. 'Tsubasa Tiger' is written from the perspective of Hanekawa rather than Araragi.
