Known for her semblance to the Sadako character of The Ring series, Sawako Kuronuma is given the nickname "Sadako" and misunderstood to be frightening and malicious like her fictional counterpart, despite having a timid and sweet nature. Longing to make friends and live a normal life, Sawako is naturally drawn to the cheerful and friendly Shouta Kazehaya, the most popular boy in her class. From their first meeting, Sawako has admired Kazehaya's ability to be the center of attention and aspires to be like him. When Kazehaya organizes a test of courage for the entire class and encourages her to attend, Sawako sees this as an opportunity to get along with her classmates, starting with Ayane Yano and Chizuru Yoshida. Through each new encounter and emotion she experiences, Sawako believes that meeting Kazehaya has changed her for the better. Little does Sawako know, her presence has also changed Kazehaya. Kuronuma Sawako is the perfect heroine... for a horror movie. With her jet-black hair, sinister smile and silent demeanour, she is often mistaken for the haunting movie character Sadako. But behind her scary façade is a very misunderstood teenager. Too shy to fit in, all she wants to do is make some friends. But when a popular boy in class befriends her, she is sure to make more than just that — she is about to make some enemies too!
