Funimation announced on Thursday that it will stream the Rumble Garanndoll (Gyakuten Sekai no Denchi Shōjo: Rumble Garanndoll, literally, Turnabout World’s Battery Girl) anime for the fall 2021 anime season.
A decade later, our Japan has been revamped as Genkoku Nippon, a puppet state of Shinkoku Nippon.
A rift to another dimension suddenly opens in the skies above, revealing a “turnabout” alternate world called “Shinkoku Nippon.”
Shinkoku Nippon invades our Japan with its “Genmu” gas weapons (on which our own modern weapons have no effect) and giant humanoid “Garan” weapons.
