Hell's Paradise: Jigokuraku

地獄楽

Gabimaru, an elite shinobi known as Gabimaru the Hollow, has been condemned to death — but no method of execution can kill him. Yamada Asaemon Sagiri, an executioner of the Yamada clan, offers him a deal: travel to Shinsenkyo, a legendary island where previous expeditions have vanished, retrieve the Elixir of Life, and the Shogunate will grant a full pardon. Gabimaru agrees for one reason — to return to his wife Yui. Ten other condemned criminals receive the same offer, each monitored by a Yamada clan member authorized to kill them at any sign of escape.
