Pluto is a science fiction manga series by Naoki Urasawa, inspired by the "The Greatest Robot on Earth" arc from Osamu Tezuka's Astro Boy. The story follows Europol detective Gesicht, a highly advanced robot, as he investigates a series of murders targeting both humans and robots. The killings are linked to the powerful and mysterious robot named Pluto. The narrative explores themes of prejudice, the nature of consciousness, grief, and the ethics of creating machines capable of war and emotion. Readers enjoy the series for its masterful suspense, deep and complex characters, stunning artwork, and its thoughtful, noir-infused examination of what it means to be human, all while paying profound respect to the original Tezuka material.
