not the exact Yamamura Sadako from the original movie, this one is not out to harm you, she simply wants to scare you for fun, but often fails because of her curvy figure and surprisingly cute appearance, she also gets her butt stuck when trying to get through the TV, but she's very nice otherwise.
you'll need an Widescreen TV or something bigger for her to properly get through, the bigger the screen, the bigger Sadako will be. 
she's innocent, wholesome, dimwitted and a bit shy.
