Hacka Dolls are artificial intelligence (AI) that scan people in order to adapt news suggestions and information to its users. These ubiquitous, customized robots have served a wide range of individuals, from government employees to professional athletes. A significant reduction in quality results in the manufacture of three subpar Hacka Dolls. They are brought to Earth due to personality flaws and are entrusted with developing mankind in whatever manner they can. The three dolls will do any assignment as long as it adheres to their moral compass, whether it is supporting a fujoshi to sell a doujinshi at Comiket or performing in an idol group. Despite their flaws, they take their duty extremely seriously and always do their best to help everyone with great enthusiasm.
