PLUTO

In a near-future where humans and advanced robots coexist, Europol detective Gesicht investigates a string of killings in which both robots and human rights advocates are found with horn-like objects driven into their heads. The trail points to a culprit targeting the world's seven most powerful robots, Gesicht among them. Reworking Osamu Tezuka's "The Greatest Robot on Earth" arc from Astro Boy, the case sends Gesicht to seek out the machines still left on that list before the killer reaches them.
