On a drizzley morning, Miss Monochrome wakes up in her four and a half tatami-mat sized apartment. When she tries to change her battery, a leak in her roof causes her battery box to explode. What should appear from the smoke of the explosion but a good-looking guy in the form of a battery! Miss Monochrome and Battery-kun are shocked by this destined encounter. Thus begins their days of friendship.
