Hell's Paradise

A group searching for the secret to the elixir of immortality arrives at the fortress of the island’s monstrous rulers, the "Tensen." To survive and leave the island alive, they must work together-whether they are condemned criminals or executioners. At the same time, the shogunate sends more forces to the island of the Immortal Realm, led by Shugen Yamada Asayemon. Among them is the Ishigakure clan, who have history with Gabimaru. With time running out, Gabimaru and his allies clash with the Tensen, sparking a full-scale battle between humans and immortals as they fight for the elixir and their freedom.
