Ginga Tokkyuu Milky☆Subway

Chiharu, a superhuman, and Makina, a cyborg, were detained for violating space traffic regulations. They are joined by other detainees—Akane and Kanata, also superhumans, and Kurt and Max, cyborg companions. Ryoko, a police officer, assigns them community service cleaning the interplanetary train known as the "Milky☆Subway." The task appears straightforward until the train unexpectedly departs into space. The group is thrown into disarray as the train moves without a clear destination or reason. The journey is marked by confusion and chaos, with no apparent goal or structure. The train continues forward solely by its own momentum, creating a bizarre and unprecedented space-train experience.
