Why it’s a Weeknight Watch

With a short run with a modest audience and little lasting buzz, it's a mixed bag. Fine if it's on; don't plan your night around it.

Based on critics, audiences, awards, box office and buzz. Details below.

Is it for you?

Who'll love it
Made for sci-fi fans and animation lovers.
The mood
Thoughtful and character-driven.
The pace
2 seasons: a few weeks of evenings, short, snackable episodes, about 40 hours in all.
What might put you off
  • Rated TV-14. Probably too much for younger kids.
  • It's in Japanese, so expect subtitles (or a dub).

When they were young, the brothers Mutta and Hibito promised each other they would become astronauts. Now, in 2025, Hibito has followed his dream to become the first Japanese on the moon, but Mutta has just been fired from his job. His brother reminds him of their childhood promise, and Mutta decides once again to aim for space.
