“You know… Light’s starting to act like a real teenager.”
Sayu Yagami (夜神 粧裕, Yagami Sayu) is Light Yagami's kindhearted younger sister, and plays a minor role in the main story-line, remaining unaware of Light's possession of the Death Note and his role as Kira.
Sayu has chocolate brown hair and brown eyes. In the first part of the story, her hair is straight and cut short, with bangs and strands of hair that frame the sides of her face. Later on her hair grows longer and has small curls at the ends, and her bangs are swept to one side.
In line with her age and grade in school she seems to demonstrate age appropriate behavior such as watching shows starring Hideki Ryuga and asking Light for help with math homework, including quadratic function assignments. She seems to look up to Light, as she sees his intelligence and believes that he will become a quality detective. According to How To Read 13, Sayu likes shoes and dislikes alcohol. In her university years, however, Sayu's attitude grows more mature and she studies on her own without Light's help.
PlotEditSayu is the younger sister of Light Yagami and a 14-year old second-year student (8th grade) at Eishu Junior High School (英集中学校, Eishū Chūgakkō) at the beginning of the story. Her role at this point in the story is rather minor. In the second part of the series, Sayu attends college. She is kidnapped by the Mafia and taken to the United States, where she is held captive in order for the Mafia to gain a Death Note. Sayu's father trades the Death Note to the group in exchange for his daughters life. Sayu is taken back home to Japan, where she falls into a state of shock and is wheelchair ridden for some time.
Sayu is last seen at a Coming of Age Ceremony. It is up to the reader to decide what her mental state is. Tsugumi Ohba said that she hasn't "necessarily recovered" but you could not tell from the picture".
