In Neo-Japan, 2100, the Empire doesn't just rule—it manages.

To maintain absolute control over seven artificial cities, the Iron Throne utilizes two blades: the Samurai Agents who enforce the law, and the Yakuza Clans who manage the chaos. It is a fragile, bloody balance of power where "peace" is bought with shadow-tax and street-side executions.

Ichiro Yoshima is the heir to the most powerful of these sanctioned clans. His life was a pre-determined path of political chess and enforced order—until he rescued a silver-haired girl marked by Angel’s Blood. With her ability to glimpse fragments of the future, she is the ultimate "illegal variable" in a world of calculated control.

Now, Ichiro's loyalty is pushed to the brink. Alongside Akira Hayashi, the last warrior of a forgotten lineage who carries a dulled katana as a silent protest against the Empire’s chrome-plated brutality, he must navigate a treacherous path.

To protect the girl and uncover the Empire’s darkest experiments, Ichiro and Akira must do the impossible: Infiltrate the elite Samurai Agents from within.

As they climb the ranks of the very system that oppresses them, the line between "Balance" and "Rebellion" begins to blur. In a city of neon surveillance, the greatest weapon isn't a blade or a hack—it’s the truth behind the Empire's veil.
