Mahoromatic

First Season: Mahoromatic: Automatic Maiden
Vesper is a secret agency fighting an army of alien invaders by using super-powerful battle androids. Mahoro is Vesper's most powerful battle android and has won many battles, but she has little operating time left and soon will cease to function. However, if she lays down her arms and conserves her remaining power, the time she has left can be prolonged to just over a year. Mahoro is given an opportunity to live the remaining time she has as a normal human. She chooses to live as a maid for Suguru, a phenomenally messy high school student who lives by himself after his family passed away.

Second Season: Mahoromatic: Motto Utsukushii Mono
(Something More Beautiful)

As the relationship between Mahoro, Suguru and his classmates develops further, another android girl enters their lives and becomes attached to Mahoro. All the while, the number of days before Mahoro is to shut down decreases steadily.
