Super human Chiharu and cyborg Makina got arrested for breaking space traffic laws.
They're stuck with a crew of misfits who got caught around the same time: Akane and Kanata, the super human pair; and Kurt and Max, the cyborg pals. Ryoko, the police officer,
sentenced them to clean up the interplanetary train – the so-called "Milky☆Subway,"
as their community service.

It should've been a simple job – until the train suddenly takes off into deep space!
