Tohru Honda is the heroine of the Fruits Basket series. She is the only daughter of Kyoko Honda and Katsuya Honda, both of whom are deceased. She moves into the house with Shigure Sohma], Yuki Sohma and later Kyo Sohma after Yuki and Shigure discovered her living in a tent on their property. She worked part-time to support herself when she was living on her own, and continues to despite moving to Shigure's house. Her two best friends are Arisa Uotani and Saki Hanajima. Tohru is very grateful to the Sohmas and loves every bit of time she spends with them.
Takaya gave Tohru a name normally used only for men because she likes to give masculine names to female characters "to balance them out." In addition, Takaya chose to have other characters address her as "Tohru-kun", using an honorific typically used for boys, because she thought it was "a more dignified form of address."
