Chuuya Koyama's Uchuu Kyoudai (Space Brothers) manga will end with the 46th volume, according to the wraparound band on the 45th volume on Wednesday.

Koyama began drawing the sci-fi space manga in Morning magazine in December 2007. Kodansha USA licensed the manga for digital release in English in October 2015 and published the 44th volume in December 2024. Uchuu Kyoudai has over 31 million copies of its volumes in circulation.

A-1 Pictures adapted the manga into a television anime that aired in 99 episodes from Spring 2012 to Winter 2014. Crunchyroll streamed the anime with English subtitles.

Synopsis
"A big brother must always stay ahead of his younger brother. That is my responsibility as the older sibling"—these are the words that have always motivated Mutta Nanba to try his best when it came to his younger brother, Hibito. So naturally, in the summer of 2006 when the Nanba brothers witness something strange in the night sky, Hibito declared that he would become an astronaut and travel to the Moon, while Mutta countered with the affirmation that he would go to Mars. That was the promise they made to each other.

Now in 2025, while Hibito is working with NASA and preparing to become the first Japanese to land on the moon, Mutta has been fired from his job in an automotive development company. Having difficulty finding another job, Mutta is given a lifetime opportunity when he receives a letter from JAXA—the Japan Aerospace Exploration Agency—telling him that he has been accepted to participate in the next astronaut selection. As if fate has given him a chance to fulfill the promise he made all those years ago, Mutta undertakes the difficult challenge of going to space. [Written by MAL Rewrite]

@ReaperCreeper So, essentially, they need another big season to close out the adaptation?

Looks like it if they want to do it justice.

This manga is a masterpiece. Sad to see it go, but love that it didn't try to milk itself, overstaying it's welcome. Looking forward to the artists next great work!

An ending is definitely a motivation to finally start this. Would also be cool if the anime somehow gets a sequel after all these years.

Have I got news for you.
