In the year 1492 of the Gregorian Calendar, in the Eastern Kingdom of Mikado... The Samurai guard the Luxurors and Casualries - the people - of Mikado. The wild Samurai Walter seeks to improve his self-taught, but unrefined skill. The Samurai Gina keeps a close, worried eye on the wild Walter. One night, the pair, while keeping watch, are suddenly transported to an unknown world... There, they see a tyrant - a demon that is far stronger than any they have encountered! As a result of the battle with the tyrant, the fate of this pair begins to shift...!

The story is set in a near-future Earth, in the aftermath of a major disaster that shifts the planet's polar axis 90 degrees, situating the poles along the equatorial line and killing everyone on Earth. A moon-based colony avoids the disaster, and begins recolonizing the depopulated Earth by establishing seven cities in strategic locations. However, to ensure the loyalty of the Earth colony, the moon establishes an orbital defense system that destroys anything that flies 500 meters in the air. When an unknown virus kills everyone on the moon, humanity becomes trapped on Earth, where the political intrigues of the seven cities continue to play out.

"He", a police officer on his shift, happened to meet "her" on the streets, by chance. Through its bold, yet delicate brushwork and elegant prose, this stylish, full-colour comic illustrates the subtle air of intimacy between these two individuals.
