Robocosan at your service! (A Hololive fanfic)

Androids, only a decade ago the prospect of having AI that was complex enough to be sentient seemed impossible, the "AI Revolution" saw the development of highly advanced androids with artificial intelligence that were so complex, they were comparable to a human.

Fumuji Haru's father was an active pioneer in making this innovation possible, his greatest creation yet, the Type-27 android was the first android that was slated to enter police and military service. However his untimely demise led to the only android of this series being relegated to maid duty, raising and protecting his son.

Roboco was a former police android turned maid, tasked with raising her creator's youngest son.
Fumuji Haru is a talented detective who wished to follow in his android mother and maid's footsteps.

When remnants of Roboco's past suddenly came back to threaten her and her master, their bond would quickly grow from maid and master to something more intimate.
