I’m up to book 5 of Kazuo Koike’s graphic novel series. Loved Lone Wolf & Cub so I tried this one out. A lot more graphic, both bloody and sexually, than Lone Wolf but not to the level of being categorized as hentai. Realizing that in Japan, Lone Wolf was probably for a more general audience than some of these other graphic novels. The artwork, by Goseki Kojima (also from Lone Wolf) is spectacularly detailed and really establishes the setting. In many instances you have page upon page of detailed artwork with no dialog or expository text.
The only gripe I have with these reprinted manga is the size. At 6 inches by 4 inches, sometimes the text puts a serious strain on the eyes.
After I’m done with this series I’m gonna try Path of the Assassin, also by Koike and Kojima.
