This year's 21st issue of Kodansha's Morning magazine is revealing on Thursday that Chūya Koyama's 29th Space Brothers ( Uchū Kyōdai ) manga volume will bundle a special edition DVD of the Uchū Kyōdai #0 anime film. The special edition DVD will contain new footage exclusive to this limited edition, and the bundle will also include a booklet of Koyama's script and storyboards. Kodansha will publish the 29th volume on September 23.

The film opened in Japan in August 2014. Koyama wrote the original scripts for the "origin story" film. A Blu-ray Disc of the film's original version (as seen in theaters) will go on sale at the same time as the special edition DVD/manga bundle.

The manga's story follows two brothers, Mutta and Hibito, who made a vow as kids to travel to space. The younger brother Hibito did become an astronaut, but not Mutta. However, Mutta's life changes one fateful day.

Koyama launched the manga in Morning magazine in 2007. Kodansha published the manga's 27th volume last November, and will publish the 28th volume on Friday. The manga won the General categories in both the 56th Shogakukan Manga Awards and the 35th Kodansha Manga Awards in 2011.

The manga not only inspired a 2012-2014 television anime series, but also a 2012 live-action film starring Shun Oguri and Masaki Okada. The live-action film earned 1.5 billion yen (about US$15 million). Crunchyroll streamed the television anime as it aired in Japan, and is also publishing new manga chapters as they are released. Sentai Filmworks licensed the television anime for North America, and is releasing the 99-episode series in eight volumes on both Blu-ray Disc and DVD.
