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.
You'll stand out much, much more with me,
ستشقِّين طريقكِ وتسبقينني بمسافةٍ طويلة
Zusammen mit mir und der Kraft der Freundschaft
Tu seras encore plus
sur le devant de la scène
Insieme a me e all'energia della nostra amicizia
Você vai se destacar mais e mais comigo
