Boku no Marie, one of the old ongoing manga series, has a robot loli
girl named
Yuri. In the
chapter 53,
Yuri downloads a
backup data with an alternative personality. This alternative personality,
whose name is
Sayuri, turns out to be malicious as she often
compellingly takes over
Yuri's body and ages it to that of a mature
woman due to her ambition and lust for becoming a sexy idol. In the
chapter 63,
Sayuri becomes greedy, and she tries to delete
Yuri's personality and keep the body to herself.
Yuri's
personality survives, but
Sayuri successfully steals the body in the
end.
