: Warning! Reading this series might not only entertain you in many ways, but it might be somewhat educational as well! Let's start with ninja skills, samurai period drama and sexy teens. Yes, we have them all in one informative, semi-historical series from the famed creators of Lone Wolf and Cub, Kazuo Koike and Goseki Kojima. It's the story of to-be shogun Ieyasu Tokugawa, in his late teens, battling and politicking his way to the leadership of Edo-era Japan. To do so, he must survive assasination attempts, political sabotage, bloody battlefields and a ferocious wife. And he does this with the help of his friend and vassal, the unstoppable ninja Hattori Hanzo. Heard these names before? That's because they're a revered part of Japan's (sometimes secret) past!
