Japan, 2019, just before the dawn of a new era. Suddenly, a rift to another dimension appears in the sky, revealing an alternative world "Shinkoku Nippon," with the sky and the earth upside down. This parallel world keeps their former militarism, with its era being Eternal Showa. The military invades the real Japan with giant humanoid robots called "Garann" and their gas weapons "Genmu", rendering our modern weapons ineffective. "Shinkoku Nippon" instantly seizes the government and achieves de facto conquest of Japan. The new era, "Reiwa," has now arrived for Japan.

Mixed Feelings
Saying true to yourself is never easy especially if you still confused to justify your feeling. I think this is the whole idea of 'Rumble Garanndoll'. Hosomichi have traumatic past that he don't really know how to solve it, especially in his current condition with huge debt and the changing world. We already know life must go on but it never easy to move on.

It has good idea for start an original story, but Garanndoll cannot fully used it to full potential. If they only focus on Hosomichi, Rin and Yamada it will become deeper story. Too many supporting cast in Garanndoll make the series ...
Dec 27, 2021
Over the many years of watching anime, I pretty much have a standard of knowing what to expect for shows, even more so for originals, where ideas can get so ridiculous and even thought-provoking at times if it chooses to do so. At least for Gyakuten Sekai no Denchi Shoujo a.k.a Rumble Garanndoll, I can respect the concept that came forth from this original expedition by famed studio Lerche director Masaomi Andou, but in all honestly, this was far from being original, was a chore to go through, and is pretty tame as a derivative of something that's already done the same, but superior in ...
