Heart Gear (stylized in all caps) is a Japanese manga series written and illustrated by Tsuyoshi Takaki. The series was serialized on Shueisha's Shōnen Jump+ manga website from April 2019 to June 2024, with its individual chapters collected into seven volumes. When creating the series, Takaki decided on using a young girl and robot as protagonists in a post-apocalyptic setting in order to write a science fiction manga that is understandable to a wide audience. Takaki also used the film Android for inspiration in creating the story and various objects from his everyday life and photos of famous places in creating the setting. The series has performed well internationally, especially in France, where its sales have surpassed those of its native country. Critical response has generally been positive, with many critics praising the characters, post-apocalyptic setting, and artwork. Source: Wikipedia (en)
