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. A secret society named Arahabaki (a Japanese anagram of Tokyo’s sub-culture shopping district Akihabara) rises up to resist Shinkoku with Garanndoll weapons powered by “battery girls.”
Masaomi Andō (School-Live!, Scum’s Wish, Toilet-Bound Hanako-kun, Astra Lost in Space) is directing the anime at the studio Lerche.

EGG FIRM is producing the anime. Mia REGINA is performing the anime’s opening theme song “Fever Dreamer,” while Aina Suzuki is performing the ending theme song “Reverse-Rebirth.”
The anime will also receive a manga adaptationb by Left Hand that will launch in Kadokawa‘s Comic Newtype website. The staff will reveal details of the manga’s artist and the debut date at a later time.
