Soichiro Yagami
Light Yagami's father, Soichiro Yagami, is a police officer who serves as the Japanese Task Force's first leader and the Chief of the NPA. He is also listed as one of the best anime father characters. Kind and with a strong sense of justice, Soichiro is a father. He takes great pride in his work as a detective. He adores his son dearly. Even so, he gave up half of his life to save his daughter Sayu Yagami's. Talking to his son on his deathbed, Soichiro expresses his belief in him. He is undoubtedly a guy of justice and a caring father.
Soichiro Yagami didn't spend much time with his family because he was frequently away from home. He did, however, live by the maxim "justice first, family later" in part. He struggles with whether or not to comply with the Mafia's demands and exchange the Death Note for Sayu when they kidnap his daughter.
His predicament stems from having to decide between his parental responsibilities and his duties as an officer. As the Chief of the NPA and a police officer, he feels that it is improper to provide the Death Note to the Mafia and that there is too much risk involved. In the end, though, he chooses to act like Sayu Yagami's father rather than an officer when he makes the transaction.
