Perfect Blue(2012)

Perfect Blue is a Japanese detective series following Hasumi Kayoko, a sharp rookie investigator at an all-female detective agency who despises lies and secrets. Seven years after her father's suicide at a newspaper, Kayoko remains haunted by unanswered questions about his death. Her mother Kyoko, who runs the agency, has quietly pursued the truth for years. When a new case lands on Kayoko's desk, it becomes the thread that unravels a larger conspiracy—one that pulls her closer to uncovering what really happened the night her father died. As Kayoko digs deeper, she discovers that the truth has been hidden in darkness all along, and that solving this case means confronting painful secrets within her own family.
