Karada is a cheerful young girl who is about to enter her first year of junior high school. Her parents passed away when she was two years old, and has since lived together with her older brother, Hiro. She looks younger than she really is and wishes to grow up faster, due to hating being treated like a child. She has also learnt how to cook and do house chores herself, due to her not wanting to worry Hiro. Her friend and classmate, Tetsuya, seems to have feelings for her. She doesn't know that Hiro is not her real brother.
