Synopsis
In 2019 Japan, on the cusp of a new era, a portal opens to a parallel dimension called "Shinkoku Nippon."
This alternate world, stuck in an eternal Showa era and clinging to militarism, swiftly invades the real Japan.
Using powerful humanoid robots known as "Garann" and devastating gas weapons, they overwhelm modern defenses.
Shinkoku Nippon quickly conquers Japan, imposing their rule and ushering in a forced "Reiwa" era.
The anime explores the conflict between these two worlds and the struggle for control of Japan.
