Milky☆Subway: The Galactic Limited Express will be streamed simultaneously on YouTube and will be available dubbed in 10 languages: English, Spanish, Portuguese, French, Hindi, Indonesian, Korean, Thai, Russian, and Chinese.

The anime’s official English website describes the main synopsis as::
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!
