Two hundred years after World War III decimated human civilization, a young teenage girl named Roue lives a humble and quiet life in the ruins of the old world alongside her "uncle," a droid named Zett. Their peaceful days of exploration are transformed when Roue discovers Chrome, a mysterious cylindrical gear with a unique anomaly: he lacks a "base program" that would normally define his primary purpose. In Takaki Tsuyoshi's evocative sci-fi adventure Heart Gear (2019), the three begin to live together like a family as Chrome struggles to find his own identity in a world that no longer remembers its creators. However, their newfound domestic bliss is soon challenged by the harsh realities of their post-apocalyptic environment and the secrets of Chrome's origin. The story blends mecha action with intimate slice-of-life moments, exploring the bond between a girl and her mechanical companions. Now complete, this mystery-driven series is an unmissable read for fans of character-focused sci-fi and beautifully realized ruined worlds.
