Even an undefeated ninja may not survive the Hell's Paradise! Gabimaru is a ninja on death row who has one last chance to see his wife by searching for the elixir of immortality on a supernatural island and delivering it to the shogun. Along the way, he faces his fellow inmates and the terrifying beasts that roam the island, devouring or killing anyone they encounter. The two fiercest warriors, Gabimaru the Hollow and Aza Chobe the King of Bandits, eventually cross paths and come into conflict. These two men are evenly matched and extremely deadly… which means their duel will be one for the ages!
