In fruits baskets what are all the zodiacs or main characters?

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
