Mobile Suit Gundam: Iron-Blooded Orphans – Urdr Hunt Special Edition: Path of the Little Challenger Kidou Senshi Gundam: Tekketsu no Orphans - Urdr Hunt: Chiisana Chousensha no Kiseki

Year P.D. 323. Gjallarhorn’s political intervention into the Arbrau central parliament escalated into an armed conflict using mobile suits. The incident was brought to an end by Tekkadan, a group of boys who came from Mars.

News of Tekkadan’s exploits has also reached the ears of Wistario Afam, a youth born and raised at the Radonitsa Colony near Venus. Venus, which lost to Mars in the contest for development, is a remote frontier planet in which the four great economic blocs show little interest. It is now used only as a penal colony for criminals, whose inhabitants don’t even have IDs.

Then Wistario, who hopes to change the status quo of this homeland, encounters a girl who claims to be the guide to the Urdr-Hunt.
