Hell's Paradise: Jigokuraku manga volume 10 features story and art by Yuji Kaku.

Finally, Gabimaru’s secret origin is revealed! Plus, a group of samurai and ninja who just arrived on the island have exactly one mission—to leave no one alive. Any who would stand in opposition to the Yamada Asaemon, and therefore the shogun, must die. Any who do not fear the power of the ninja village Iwagakure must die. Gabimaru, Sagiri and the others have overcome a great deal, but this will be a struggle like they’ve never experienced before.
