Sayu Yagami

Sayu Yagami (夜神 粧裕, Yagami Sayu) is Light Yagami's kind-hearted younger sister, who plays a minor role in the main story, unaware of Light's possession of the Death Note and his role as Kira.

Sayu is a very young girl who grows up over a period of time throughout the story. Her hair and eyes are brown. In the first part of the story, her hair is long and tied up, with bangs and strands of hair framing the sides of her face. Later, she grows a lot at 20 years old and has small curls on the sides, with her bangs to one side. She usually wears casual clothes.

Sayu appears to display behavior appropriate for her age and grade level, being a fan of actor Hideki Ryuga and asking her brother, Light Yagami, for help with her math homework, mainly for quadratic functions. She believes that Light will become a great detective due to his high intelligence. According to How to Read 13, Sayu loves shoes and hates alcohol. Apparently, in her college years, Sayu's attitude changes, and she becomes more mature, studying on her own without Light's help, among other things.

Sayu is Light Yagami's younger sister and a 14-year-old second-year student (eighth grade) at Eishu Junior High School (英集中学校, Eishu Chugakko) at the beginning of the story. Her role at this point in the plot is fairly minor, making small appearances.

In the second part of the series, Sayu attends college. She is kidnapped by the mob controlled by Mello and taken to the United States, where she is imprisoned, in order to bribe the Japanese Police and obtain a Death Note. Sayu's father trades the Death Note to the mob group in exchange for his daughter's life. Sayu is taken back to Japan, where she falls into a deep state of post-traumatic stress due to the situation she had to live through, and is put in a wheelchair for a time.

Also being left with great sadness and depression after learning of the death of her father Soichiro Yagami and also her brother Light Yagami, affecting her more by the fact that he was the person who was really behind all the murders done by Kira all the time.
