Former elite combat android Mahoro has fulfilled her service in the ranks of the Vesper armed division. Her creators, however, sadly realize that under combat operating parameters, Mahoro will cease to function in 368 days. Due to her faithful and unfailing service to the Vesper corporation, they offer an alternative, to disarm and live out a peaceful life for one year. Mahoro chooses to live out her remaining days, not as a combat android, but as a maid under the employ of young Misato Suguru, a high school boy. Yet as she spends her remaining time in a peaceful life with Suguru, Mahoro's past is slowly catching up to her. <br />
