Tohru Honda (本田 透, Honda Tōru) is the main protagonist of the Fruits Basket series. She is the only daughter to the late Kyoko and Katsuya Honda.

Tohru Honda is a student at Kaibara Municipal High School. She loves to cook, describes herself as an excellent housekeeper, and has an after-school job as an office janitor to pay her tuition fees to avoid being a burden to her relatives. She is depicted as a polite, optimistic, independent, extremely kind, and selfless person with a nurturing personality.

Following her mother's death which left her orphaned, Tohru Honda begins living with Shigure, Yuki, and Kyo Sohma due to accidentally setting up a tent on their property, and later being hired as their landlady. She later learns that thirteen members of the Sohma family are cursed, as they turn into animals of the Chinese Zodiac if they are embraced by anyone of the opposite sex or when their bodies come under a great deal of stress. As the series progresses, Tohru meets and befriends the rest of the zodiac and the family's mysterious head, Akito Sohma, and resolves to break the curse that burdens them. Only later does she admit that she wants to free Kyo most of all.
