Mahoromatic: Automatic Maiden

まほろまてぃっく

Mahoro is the strongest combat android of Vesper, a secret agency fighting alien invaders, but her power source is nearly spent. Offered a choice between a few more days as a warrior or a longer quiet life with her abilities stripped, she chooses the latter and asks to spend it as housekeeper for Suguru Misato, the orphaned teenage son of the officer she once served. She moves into his home and takes up domestic life while her countdown ticks down.
