Light Yagami (See full character profile)
Soichiro Yagami (See full character profile)
Sachiko Yagami is wife of Soichiro Yagami and the mother of Light. Like her daughter Sayu, she is unaware of Light ever being Kira even after his death. She is portrayed by Michiko Godai in the live-action films.
Sayu Yagami is Light's younger sister. Like her mother she never learns of Light's possession of the Death Note or his identity as Kira. In the manga and anime, Mello's gang kidnaps her in exchange for the Death Note possessed by the investigation team. Although being returned unharmed, Sayu falls into a state of shock, eventually becoming unresponsive to the presence of others. In the live-action films her character is portrayed by actress Hikari Mitsushima, and since the mafia does not play a role, she is not kidnapped.
