Pluto: Urasawa x Tezuka 4

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. A powerful, destructive force in the form of a tornado is killing the great robots of the world one by one. Who or what could be behind this whirlwind? Be it man or robot, it now has its sights set on Atom, the most advanced robot ever created--and Atom is ready to dive right into the eye of the storm.
