Light Yagami manipulates his family members in the series "Death Note" by using his intelligence, charisma, and the power of the Death Note. He initially manipulates his father, Soichiro Yagami, by pretending to be a model student and gaining his trust. He also manipulates his sister, Sayu Yagami, by appearing to be a caring and protective older brother. As the series progresses, Light's manipulation becomes more sinister as he uses the Death Note to control and influence his family members' actions to achieve his goal of creating a utopia under his rule.
