The classic science fiction–horror manga from the mind of Kazuo Umezz, creator of The Drifting Classroom, Orochi, and Cat-Eyed Boy!

When an industrial robot named Monroe begins to work at his father’s factory, Satoru is fascinated. As he and his friend Marin spend more time with Monroe, they start to suspect there’s much more to the machine than anyone else realizes. But neither children nor adults are prepared for Monroe’s violent awakening into consciousness.

As the robot Monroe grows ever more intelligent and self-aware, so too does his obsession with finding Satoru and Marin, the children who brought him into this world. After a harrowing escape from Japan, Monroe sets sail for England, where Marin is forced into one horrifying situation after another by an obsessive acquaintance as she struggles to reconnect with the memories she has lost.
