Onion is blind, mute and orphaned at a young age. Despite his misfortunes, he remains upbeat and outgoing; though he's never plucked up the courage to declare his love for Autumn, a nurse at the hospital where he works as an audio tape typist. One day, Onion gets run over by a car, and finds himself in transit to Polaris. However, no one could embark on the journey with a negative disposition. Having been one hell of an unlucky guy in life, Onion asks his celestial escort for one chance - to return to Earth for five days, to make Autumn happy.
