Jun Harukawa

A sadistic Daimyo (feudal lord) rapes a woman and murders both her and her husband, but even when one of his own vassals commits suicide to bring attention to the crime, the matter is quickly hushed up. Not only will there be no punishment, but because the Daimyo is the Shogun's younger brother, he will soon be appointed to a high political position from which he could wreak even more havoc. Convinced that the fate of the Shogunate hangs in the balance, a plot is hatched to assassinate the Daimyo. The two most brilliant strategic minds of their generation find themselves pitted against each other; one is tasked to defend a man he despises, and has a small army at his disposal. The other is given a suicide mission, and has 12 brave men. They are the 13 Assassins.

A wave of terror is threatening to unseat Shogun Yoshimune. Police stations are erupting into flames, convicts escaping from prison, houses robbed and vandalized, streets teeming with panicked citizens. Is Ijyuin Tanomo, highly-placed official of Owari clan, secretly using deadly ninja to foment riot and rebellion? Narumiya Shinbei, a lone samurai spy adept at ninjutsu must uncover the hidden hand orchestrating these shocking crimes. Shinbei enlists a small band of dedicated ninja to lay siege to the enemy’s stronghold, where his own sister works as an undercover agent. Now, ninja must fight ninja in a last desperate battle to save the shogunate.
