Milky☆Subway: The Galactic Limited Express

Arrested for reckless space driving, super human Chiharu and cyborg Makina are sentenced to clean the Milky☆Subway—an old interplanetary train. Easy enough, right? Wrong. When the train suddenly takes off, they are thrown into a high-speed space-train spectacle packed with chaos, no plans, and zero strategy. Just pure momentum!
