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! The crew scrambles in confusion as chaos unfolds onboard! No purpose! No principle! No point! A never-before-seen space-train spectacle, powered by nothing but pure momentum! (Source: Official website)
