Even an invincible ninja may not be able to survive Hell’s Paradise!
Gabimaru is a ninja on death row with one chance to see his wife again—by finding the elixir of immortality on a supernatural island and delivering it to the shogun. Standing in his way are his fellow convicts and the fearsome beasts that roam the island, devouring or killing anyone they encounter.
