Legacy Sisters™ is a kinetic visual novel like story that takes place in a futuristic year 2000 Silicon Valley like setting. It centres on a young woman named Ampa, who is 19 years old and fiercely independent. She likes and works with technology but distances herself from using it personally due to anti-trust concerns toward the companies that create it and the data mining associated with them.
She lands on a very significant discovery, a robot named Aarel (RL-117) who is a working prototype resembling a human in every way – built in 1982, prior to a technology crash that saw ceased production of any further human resembling robots. These robots were subsequently banned and never made again in favour of pet-like personal robot companions that replaced them.
Ampa is fairly well off for her age despite working a menial job at a tech company named Ample Computer. With a bit of entrepreneurial excitement, she sees a potential in Aarel not even seen in technology of the time that she wishes to reveal. She lets her guard down for a moment and posts pictures of Aarel on the Internet. This makes Aarel, who is one of a kind, a massive target of interest; not only to the company that built her, but to rivaling tech companies as well.
Aarel ends up being located, stolen, copied, and modified with weaponry but uses it to escape and return to Ampa. How many of these other robots resembling humans exist, hiding in plain sight or behind closed doors? Ampa suspects that the company she works for, Ample Computer, has the ability to produce such a robot and after seeing Aarel, fully believes the rumour that they may have already done so. She uses Aarel as key leverage to exploit this suspicion, thus Ampa and her robot, Aarel embark on their journey…
