Even an invincible ninja may not be able to survive Hell's Paradise!

Gabimaru the Hollow is one of the most vicious ninja assassins ever to come out of the village of Iwagakure. He's ruthlessly efficient, but a betrayal results in him being handed a death sentence. There is only one hope: travel to a long-hidden island and recover an elixir that will make the shogun immortal and he will regain his freedom. Failure is not an option-on this island, Heaven and Hell are a hair's breadth away.

Gabimaru and Yamada Asaemon Sagiri arrive on the mysterious island on the hunt for an elixir of immortality to deliver to the shogun. They find inhuman beasts that appear like corrupted, violent versions of divine beings. This paradise sits between heaven and hell, and it's entirely possible that no one will come back alive...
