Original title (JP): ミルキーサブウェイ (Mirukīsabuu~ei, Milky Subway)

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!
