Now that it’s fully out (last episode), I’m recommending this show.

It’s dubbed in 11 languages and you can watch for free on YouTube.

The characters and dialogue are great, not just by indie standards (each episode is ~3-5 minutes) but by general anime standards.

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!
