Hell's Paradise

Gabimaru the Hollow, a ninja sentenced to death for his past crimes, is executed multiple times but still manages to survive. His apathy towards living is challenged by Sagiri Yamada Asaemon of the Asaemon executioner clan, who instead offers Gabimaru a chance to save his life. To achieve this, Gabimaru would need to travel to the island of Shinsekyo and retrieve the Elixir of Life, a mythical substance said to grant immortality, for the shogun.
