A good men from «SHAFT» came to a Japanese psychiatric clinic, where the crazy creators of the anime are taked care of, and asked the patients to do a new "Madoka" movie, but not just a bonus to the BD-edition, but the continuation of a story, so that was even more wtf and omg.
At the same time, the studio did not stint on gifts and treated its to new employees by various kinds: writers were treated with the purest cocaine, and artists — a selected mushrooms with LSD.
So, «The Rebellion Story» was born.
And it's good.
