Synopsis
After World War II, Japan was divided into east and west by the "wall of Hakone". The eastern side changed its name to the Socialist Republic of Japan, and created a one-party dictatorship, as opposed to western Japan, which had the emperor in Kyoto and actively adopted the culture of western countries. And one day, the countdown for Japan integration was approaching four years later. A girl departed from Hokkaido, which became Russian territory. Her name is Nora. She is a member of the National Liberation Army "HRA". Having no memory of her past, she heads to the capital of eastern Japan, "Tokyo Prefecture," to unravel the mystery of her birth. That was the beginning.
