Soichiro Yagami – Death Note
Soichiro Yagami (夜神 総一郎 Yagami Sōichirō) is Light’s father and a police officer that initially leads the Kira investigation team that later joins with L. When L begins to suspect Light of being Kira, Soichiro is unwilling to believe his son would be capable of such a thing. After L’s death, he is sent to retrieve the Death Note stolen by Mello by obtaining Shinigami Eyes and infiltrate Mello’s hideout, though Light had planned for Matsuda to fill the role. He retrieves the note and learns Mello’s real name, but is unable to kill him, and is instead fatally wounded. Because Light has given up his Death Note, making his lifespan visible above his head, Soichiro dies believing that Light is not Kira. In the film series, Soichiro, portrayed by Takeshi Kaga, survives – discovering that Light is Kira and holding him as he dies – but chooses to hide the knowledge from his family.
