In the anime "Fruits Basket," the character that represents the ram in the Chinese zodiac is Hatsuharu Sohma. Hatsuharu is known for his dual personalities, with his calm white side and his aggressive black side symbolizing the nature of a ram.
The optimistic Tohru Honda is the main character. She was orphaned when her mother died in a car crash. She lived with her grandfather. When he had to have his home remodeled, she went to stay in a tent so not to be a burden on anyone. Through a chain of events, which included her tent being destroyed, she came to stay with some members of the Sohma family. This is where the story began to really develop. http://content.answers.com/main/content/wp/en/thumb/c/ce/230px-FB_tohru3.jpg
