Title: Fruits Basket
This story revolves around our lovable, orphaned main character, Tohru Honda. Tohru's life is filled with hardship. Her father passed when she was a young girl, her mother died not long before the start of our story, she is forced to live in a tent in the woods due to her grandfather's home renovations and an unkind family living with him, and she works a cleaning job to pay her own way in the world while also attending school.
What Tohru doesn't know is that she has mistakenly started camping inside the land of the Sohma clan, a family of mysterious, attractive men and women who mostly keep to themselves. One of the main members is Yuki Sohma, who goes to school and is in the same class as Tohru, though they do not interact as Yuki is very distant at school. Tohru ends up accidentally stumbling across the house where Yuki is staying, thus encountering the second Sohma Shigure, an older and unreliable author who cares for Yuki as a guardian.
When Yuki and Shigure question how she found their house, they discover she is living in a tent. For her safety, they ask her to stay with them, at least until her grandfather's home renovations are complete. While Tohru is unwilling at first, as she fears being a burden on people, a landslide ends up crushing her tent, which forces her to accept the Sohma's offer.
During her first day with the Sohmas, she ends up meeting Kyo, another Sohma member who hates Yuki with a passion. He challenges Yuki to fight, which, of course, shocks Tohru, but Yuki and Shigure are not surprised in the least. While trying to stop him, Tohru ends up accidentally embracing him, and when she does, Kyo turns into a cat. It is then revealed that Kyo (the cat), Yuki (the rat), and Shigure (the dog) are all part of the Sohma curse, which causes 13 members of the family to turn into the 13 animals of the Chinese zodiac whenever a member of the opposite sex embraces them.
