Pluto

Pluto (プルートウ, Purūtō) is a manga series by Naoki Urasawa published in Shogakukan's Big Comic Original from 2003 to 2009. It has been licensed for release in English by Viz Media, under the name Pluto: Urasawa x Tezuka. (It was released over 8 volumes between 2009 and 2010.) Takashi Nagasaki is credited as the series' co-author. Makoto Tezuka, Osamu Tezuka's son, supervised the series.

The series is based on Osamu Tezuka's Astro Boy, specifically "The Greatest Robot on Earth" (地上最大のロボット, Chijō saidai no robotto) story arc, and named after the arc's chief villain. Urasawa reinterprets the story as a suspenseful murder mystery starring Gesicht, a Europol robot detective trying to solve the case of a string of robot and human deaths.

Plot
Pluto follows the European robot detective Gesicht (German for face) in his attempts to solve the case of a string of robot and human deaths. The case becomes more puzzling when evidence suggests a robot is responsible for the murders, the first one in eight years. The series recently ended after its 65th chapter.

Numerous references to other characters in Osamu Tezuka's Star System appear, such as Black Jack, Robita, as well as several Astro Boy characters who appear in chief supporting roles.
