A new original anime called Gyakuten Sekai no Denchi Shoujo (The Reverse World’s Battery Girl) has been announced. A release date has not yet been revealed, but the production is underway.
The anime’s website displays the words “Rumble Garanndoll” underneath the Japanese title, but it is unknown if they serve as the English title of the anime or a subtitle.
The staff includes Masaomi Andou (Toilet-Bound Hanako-kun) as director, Maokoto Uezu (Drifting Dragons) as series composer, Akio Watanabe (22/7) as character draft designer, and Keiko Kurosawa (Astra Lost in Space) as character designer. EGG FIRM is producing the show, while Lerche is in charge of the animation production.
