Description
Personality
Sayu Yagami is portrayed as a kind-hearted and relatively naive young girl, especially in her younger years. She demonstrates age-appropriate behavior, looking up to her older brother Light and displaying typical teenage interests. While close to Light initially, their relationship becomes somewhat distant as Light becomes increasingly consumed by his role as Kira. Following a traumatic kidnapping, Sayu experiences significant emotional distress, becoming withdrawn and traumatized. Even after the incident, her personality remains largely defined by her initial kindness and vulnerability, though marked by the lasting impact of her ordeal. Across different adaptations, her personality remains consistent in her core traits, though her age and maturity level vary.
