Gundam Sousei sure is meta. A franchise has to be established for at least as long as Gundam has been for anybody to even consider fictionalizing the story of its own creation. In the case of Gundam Sousei, it is to the story of Gundam's production what Sengoku Basara is to the Warring States period. Industry personalities who have, since this time, become legendary are recalled with the godlike awe that only thirty years of obsessive fandom could summon.
Creator Yoshiyuki Tomino is an omniscient ultra-badass who beats Amuro's voice actor up to get just the right brat line out of him ("You hit me twice! Even my old man never hit me!"). Character designer Yasuhiko Yoshikazu is the cold genius pretty boy archetype, living large off his work on Yamato at Academy Studios. At first dismssing the Gundam project as a toy commercial, he's compelled into the slums at Sunrise after seeing Tomino's ahead-of-its-time script ("Yoshiyuki Tomino, you bastard!") Char's voice actor, Shuichi Ikeda, walks into the audition puking drunk and bombs it, only falling into the role when he sees artwork of Char and realizes that he is this character.
We only have three chapters of this (courtesy of a translating group consisting of one awesome dude), but I assume the treatment for everybody who worked on Gundam will be consistent throughout. For now, grab those chapters here, here, and here, because nobody's ever going to pick up something like this in the West ever. It assumes that Gundam is popular, you see.
