Well, Tohru was the one to discover the secret...the curse...the horribleness...yes, she was the one...wow, sorry! Anyways, Tohru's mom died (sad, sad) and she lives in a tent (um, used to). One day, on her way to school, she saw a house and it happened to contain Yuki, her school pal (I assume) and Shigure. Then, after a while of talking amongst themselves and stuff, she accidentally discovered their curse by discreetly falling on them when she met Kyo. (Right? Am I right? Sorry if I'm wrong...) So now she lives with them (you know, Kyo, Yuki, and Shigure) after figuring that she wasn't fit with her other family (like, she was an onigiri) and that she would miss her caretakers before her grandpa's home was finished being remodeled. That's Tohru! She's very sweet and kind!
