The year is 2019, right before Japan changes over to a new historical era. A dimensional rift suddenly opens up in the sky and on the other side lies a topsy-turvy world with an alternate version of Japan called Shinkoku Nippon. In this parallel world, Japan has maintained its former militarism, remaining in an eternal Showa era. Shinkoku Nippon invades the Japan we know, deploying “Genmu”, gas weapons that nullify our modern day weapons, and giant humanoid weapons called “Garann”. In the blink of an eye, the invaders seize control of the government and conquer virtually all of Japan. And thus, the Reiwa era is never ushered in.

A decade later, Japan has lost its name and sovereignty—now existing as Genkoku Nippon, a vassal state of Shinkoku Nippon. Under harsh censorship, the once thriving manga, anime, idol, and other subcultures have completely died off...or so it seemed.

But otaku culture is not dead!

There exists a group of people who directly oppose Shinkoku Nippon in order to protect Japan’s subcultures. The name of this secret society is Arahabaki, and their main weapons are “Garanndolls”, powered by female warriors who have come to be called “Battery Girls”.

Akatsuki Shinonome: Takuma Terashima

A captain in the Shinchu Army, his exemplary record as a military man has earned him a position of command on Genkoku and the undying respect of his subordinates. He feels sympathy for these “weak” Japanese citizens and works tirelessly to unite both countries under one banner. While he feels a disdain for people with their heads in the clouds, he has developed the smallest of soft spots for Genkoku’s culture.

Hayate Makami: Rina Hidaka

A Shinchu Military Academy alumnus, the way of the warrior is the only path she has ever walked. However, that serious mindset sometimes leaves her vulnerable. Hayate has sworn her allegiance to Akatsuki, but her teenage mind seems to venture beyond military matters from time to time. She will follow orders when given but has a tendency to act independently and go a little too far.

Musashi Sashigami: Yukiyo Fujii

Musashi hails from nobility. Despite her pedigree and natural military savvy, there’s no hiding her sadistic nature. Even Akatsuki can’t order her around. In fact, she’s more of a berserker than a soldier.

Yakumo Kamizuru: Shino Shimoji

Yakumo is a descendant of sorcerers who works as a mechanic in the Shinchu Army. Not only does she excel at incantations and reading the energy of the land, she is head and shoulders above the rest in scientific fields as well. Yakumo is also overseeing the development of Shinchu military temples. The more provocative side of Genkoku’s culture tends to get under her skin.
