Pluto: Urasawa x Tezuka, Vol. 3: Volume 3

In a distant future where sentient humanoid robots pass for human, someone or some thing is out to destroy the seven great robots of the world. Europol's top detective Gesicht is assigned to investigate these mysterious robot serial murders - the only catch is that he himself is one of the seven targets. Gesicht, the detective assigned to the case, has deduced that the killer is targeting the great robots of the world - which means that he too is one of the targets. The leaves of this mystery masterfully unfold into a complex intersection of reactionary robot hate groups, global politics, and an exploration of robot identity.
