Sentai Filmworks has announced that the company has acquired the license for the AKB0048 anime series, which is inspired by and stars the all-female idol group AKB48. The company will release the 26-episode series through “select digital outlets” soon, with a home video release scheduled for later in 2013.
The show’s story is set in a post-apocalyptic, totalitarian future, when a group called AKB0048 assumes the name of a legendary idol group from the past. AKB0048 holds guerrilla concerts to combat the Super Galactic Alliance’s Entertainment Prohibition Law.
AKB0048 premiered in Japan in April 2012.
