In a rapidly changing world, a sinister game of life-or-death brutally culls Japan's fading warrior class. Who is rounding up the few who still cling to their swords and is forcing them to fight? And who will be the last samurai standing?

It is the 11th year of the Meiji era in Japan, and more than a decade since the samurai were stripped of their privileges, with swords outlawed on public streets. A mysterious poster appears in all corners of the land, luring those skilled in martial arts to Kyoto with the promise of riches beyond common imagination. As warriors deprived of purpose flock to the appointed place at the appointed time, what awaits them is no ordinary task, but an all-out war—against each other! (from Kodansha USA)
