This Synopsis was written by me.
After losing her mother in a traffic accident, Tohru Honda found herself living all alone in a tent in the woods. But little did she know that those woods were property of the renowned Sohma family. Shigure and Yuki Sohma, who lived in the house not too far from where Tohru was staying, discovered her and, feeling sorry for her, decided to let her stay with them for a little while. Yuki happened to go to the same high school as Tohru, and he was also one of the most popular boys in school(with his own fan club) so Tohru was more than shocked to be in the same house as "Prince" Yuki. All seemed well for a while...until Tohru accidentally stumbled upon the Sohma family's well-kept secret: whenever one of them is hugged by a member of the opposite sex, or when their bodies are under a lot of stress, they transform into an animal of the Chinese Zodiac!(Shigure's animal is the dog and Yuki's is the rat.) Tohru promised to keep their curse a secret, but before much else can be said, she's introduced to another Zodiac member - brash, hot-headed Kyo Sohma, whose animal, the cat, isn't considered a true member of the Zodiac and is shunned by the others. Not only that, but Kyo is practically the complete opposite of calm, well-mannered Yuki, and the two share a mutual and bitter hatred for each other. They're constantly fighting(and destroying the house in the process) and they absolutely refuse to accept one another(the cat and the rat aren't supposed to get along, are they?)
When someone discovers the Sohma family curse, their memory is often erased by Hatori Sohma(who's the family doctor and also the dragon of the Zodiac.) However, Shigure, Yuki, and even Kyo are touched by Tohru's kindness and overflowing concern for others, so it's decided to leave her memory of them intact for a while. They also decide to let her live with them, and she does the cooking and cleaning for them in return. Even though this much is settled, there's still tension in the air because of Yuki and Kyo's relentless enmity. However, as the two of them spend more time with Tohru, her warmth and cheerfulness begin to slowly melt away their suppressed anger and inner conflicts. Gradually, the will to fight with each other becomes less and less, and they begin to feel more concern for her than for the need to despise each other. Not only that, but meeting Tohru has the same affect on the other members of the Zodiac too, who all suffer because of their curse, especially in their relationships with other people. As Tohru encounters happy-go-lucky Momiji the rabbit, shy, self-conscious Kisa the tiger, insecure Ritsu the monkey, as well as the other troubled Zodiac members, her selfless and caring heart touches each of their lives, and after meeting her, they end up feeling better about themselves. One by one, Tohru gives each of them the courage to confront their greatest fears and the motivation to find the good qualities that they never knew they had. Despite still being haunted by the grief of her mother's death, Tohru is constantly supported by her two best friends Saki and Arisa, as well as the Zodiac members that she befriends. She always manages to keep a smile on her face, and she has an invisible power to make others do the same, in spite of how tragic things may seem.
However, there's one Sohma whom Tohru's kindness is not able to reach. The mysterious Akito Sohma, who's the head of the family though not a member of the Zodiac. He's always been slightly distrustful of Tohru and he may be the one to decide that her memory should be erased after all! And as if this isn't bad enough, just as Kyo's rage and anger were beginning to lessen because of his time with Tohru, it's discovered that he has a deadly and wicked secret locked deep inside of him and, when that secret is finally unleashed, Tohru may be the only one who can save him from his own inner demon!
