The website for the original anime Gyakuten Sekai no Denchi Shōjo: Rumble Garanndoll (literally, Turnabout World’s Battery Girl) posted its first promotional video and key visual on Friday. The website and the video unveiled the anime’s main cast, story introduction, and October television premiere. (The website features the words “Rumble Garanndoll,” but it is currently unclear if that is the English title of the work, a subtitle of the Japanese title, or a tagline.)
The main cast members are:
Ai Fairouz as Rin Akagi, a fan of anime and live-action tokusatsu (special effects) works
Aina Suzuki as Yuki Aoba, an underground idol
Shiori Izawa as Misa Kuroki, a genius hacker who loves retro games
The story begins in 2019, just before the change in historical eras for Japan. A rift to another dimension suddenly opens in the skies above, revealing a “turnabout” alternate world called “Shinkoku Nippon.” This parallel version of Japan maintained its militarism and remains stuck in the Showa era. Shinkoku Nippon invades our Japan with its “Genmu” gas weapons (on which our own modern weapons have no effect) and giant humanoid “Garan” weapons. The invaders immediately take over our government and all but conquer Japan. As a result, our Japan never ushers in the Reiwa era.
A decade later, our Japan has been revamped as Genkoku Nippon, a puppet state of Shinkoku Nippon. Under harsh censorship, the once thriving manga, anime, idol, and similar sub-cultures have completely died off … or so it seemed.
