Pluto Urasawa x Tezuka Vol 2

Who Killed Astro Boy? Who Killed Astro Boy? In an ideal world where man and robots coexist, someone or some thing is after the seven great robots of the world. Interpol assigns robot detective Gesicht to this most strange and complex case--and he eventually discovers that he is one of the targets! An advocate for robot rights and a renowned European robot have been murdered. 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. Gesicht takes it upon himself to warn the potential targets, and Atom, the famous boy robot from Japan, is next on his list. Elsewhere, the Turkish robot hero Brando sets out on his own to take on a mysterious challenger. As the robots traverse a labyrinthine path edging toward their own souls, the question remains: Who is the killer and what is his motive?
