The drama Musume no Inochi wo Ubatta Yatsu wo Korosu no wa Tsumi desu ka? continues to draw attention with its emotionally charged storyline and striking concept. Led by Saito Kyoko and Mizuno Miki, the production has recently announced the addition of several cast members, expanding the drama’s complex world. Joining the lineup are Otomo Karen, Mizushima Rin, Sato Tasuku, Kato Konatsu, Nagano Ryota—known for his role in Genin wa Jibun ni Aru.—and Naito Shuichiro. Their involvement promises new dimensions to the already intense narrative.
At the heart of the drama is Shinohara Reiko, a mother who loses her daughter due to bullying at kindergarten. The trauma drives the 55-year-old woman, played by Mizuno Miki, to undergo full-body plastic surgery in order to become a 25-year-old version of herself, portrayed by Saito Kyoko. With her new identity, Reiko infiltrates the circle of mothers whose pressure led their own daughters—and hers—to tragedy. Beneath the surface of suburban normalcy lies a calculated plan for revenge, wrapped in grief, regret, and the desperate search for closure.
The series began airing on October 7, occupying the “Ka Dora★Eleven” slot at 23:00 every Tuesday on KTV and Fuji TV. With its mix of suspense, social commentary, and emotional intensity, the drama has sparked discussion among viewers, especially regarding themes of justice and personal transformation. The newly announced cast members are expected to bring fresh energy and deepen the interpersonal drama as Reiko’s mission unfolds.
