Hacka Dolls are AIs that scan individuals to tailor news recommendations and information for their users. These widespread, personalized robots have served many citizens, ranging from government officials to professional athletes. A sharp decline in quality results in the production of three substandard Hacka Dolls. Due to their personality defects, they are sent to Earth with the mission to advance humanity in any way they can. Whether it involves encouraging a fujoshi to sell a doujinshi at Comiket or performing in an idol group, the three dolls will complete any task as long as it aligns with their moral compass. Despite their shortcomings, they take their mission very seriously and always strive to assist everyone with incredible enthusiasm.
